5 EXECUTIVE SUMMARY There re two quifer systems underlying estern Plm Bech County, the shllow Surficil Aquifer System nd the deeper Floridn Aquifer System. This ssessment focused on the Surficil Aquifer System which is widely used for irrigtion nd public wter supply in the study re. The Floridn Aquifer System, which hs generlly poorer wter qulity nd lower yields thn the Surficil Aquifer System, is infrequently used t present. Surficil Aquifer System The Surficil Aquifer System is the sole source of fresh ground wter in estern Plm Bech County. The system's most productive zone, commonly clled the Turnpike quifer, is the northern extension of the Biscyne quifer. It is composed primrily of highly solutioned, extremely productive limestone. Throughout most of the Surficil Aquifer System, the Biscyne quifer is surrounded by modertely productive intervl of sndy shell, modertely solutioned limestone, or modertely to well solutioned sndstone which is one-fifth to one-tenth s productive s the Biscyne quifer. Most ground wter in the study re is withdrwn from either the Biscyne quifer or from the modertely productive intervl; therefore, these re referred to collectively herein s the production zone. Productivity in the reminder of the Surficil Aquifer System, which is composed primrily of snds, is low. The extent of the Biscyne quifer in Plm Bech County is irregulr. It extends from the Plm Bech - Browrd County line north to pproximtely Hood Rod where it pinches out. It lso generlly pinches out before reching the cost to the est nd Wter Conservtion Are to the west. The Biscyne quifer is thickest long its centrl portion between the Florid Turnpike nd Militry Tril (SR 89) where it is typiclly 4 to ft. thick south of the M cnl. The Biscyne quifer thins to generlly less thn 4 ft. thick north of the M cnl. The production zone is most importnt in the study re north of C-5 where the Biscyne quifer is less dominnt thn in the southern re. The production zone underlies most of the northern study re nd is known to be bsent only in smll re est of Militry Tril between 45th St. nd North Lke Blvd. Its extent in the western prt of the re, from the L-8 cnl est pproximtely 4 to 6 miles, is uncertin due to lck of dt. The production zone in the northern hlf of the study re is thickest, greter thn ft., ner the Florid Turnpike nd Okeechobee Boulevrd (SR 74) just north of the C-5 cnl where the Biscyne quifer is thickest. It is lso greter thn ft. thick long north/south strip extending 3 to 6 miles west from the Florid Turnpike nd in the res between Donld Ross Rod nd PGA Boulevrd. The Ground Wter Flow Models Two three-dimensionl ground wter flow models of the Surficil Aquifer System in estern Plm Bech County were developed; one for the study re between C-5 nd the Plm Bech-Mrtin County line (north model) nd one for the re between C-5 nd the Hillsboro cnl (south model). These models were used to quntify fctors such s rechrge, evpotrnspirtion, cnl lekge, nd ground wter drwdowns under different meteorologic, hydrologic nd mngement scenrios. The vlues presented in the conclusions represent the best presently vilble estimtes of these quntities. It is possible tht certin vlues will chnge when dditionl informtion becomes vilble nd the models re further refined,

6 however, this should not chnge the reltive importnce of the fctors discussed below. Rechrge to the Surficil Aquifer System Rinfll provides pproximtely 85 percent of the totl nnul quifer rechrge in the study re under present conditions. An dditionl 3 percent of the totl nnul rechrge is provided by lekge from mintined surfce wter systems. Over hlf of this comes from the Lke Worth Dringe District (LWDD) cnl system which covers close to hlf the study re. The remining nnul quifer rechrge comes primrily from ground wter underflow into the study re from Wter Conservtion Are (WCA-). Dischrge/Wter Use from the Surficil Aquifer System The lrgest ground wter losses from the Surficil Aquifer System in the study re result from evpotrnspirtion which ccounts for pproximtely 6 percent of the verge nnul losses under present conditions. Lekge to cnls in the study re, the next most importnt dischrge from the quifer, ccounts for n dditionl percent of the losses. Close to hlf of the ground wter dischrge to cnls occurs in the LWDD system. Allocted withdrwls by ground wter users mke up nother 5 percent of the estimted nnul ground wter losses. Remining losses come primrily from lekge into the C-5 nd Hillsboro cnls long the study re boundries. Ground wter underflow out of the study re long the Intrcostl boundry is smll, less thn percent of the totl ground wter losses. Impcts of Allocted Wter Use on the Surficil Aquifer System Ground wter level drwdowns in the study re resulting from presently llocted ground wter withdrwls re gretest in res where the quifer trnsmissivity is lowest nd there is little rechrge from surfce wter systems. The lrgest simulted drwdowns in the study re, greter thn ft., occur t the Lke Worth wellfield. Substntil drwdowns lso occur t the Boynton Bech, Delry Bech, Jupiter, nd Secost wellfields which hd drwdowns greter thn 8, 4, 4 nd 4 ft., respectively. Ground wter withdrwls re significntly incresing the potentil for slt wter intrusion long the cost in portions of the study re. Withdrwls by the Boc Rton Hotel nd Ycht Club, the Royl Plm Ycht nd Country Club, Boc Rton, Highlnd Bech, the Boc Teec Corportion, Delry Bech, Boynton Bech, nd the Gulfstrem Golf Club re ll incresing the costl intrusion potentil south of C-5. North of C-5, presently llocted withdrwls hve significnt effect on slt wter intrusion potentil only in the res est of the Secost North Plm Bech, Secost Burm, nd Rivier Bech estern wellfields. Potentil environmentl impcts resulting from presently llocted withdrwls re limited primrily to the Loxhtchee Slough in the northern study re where the combined cumultive impcts of llocted withdrwls t the Jupiter nd Secost Hood Rod wellfields cuse simulted wter tble drwdowns of to 3 ft. t the estern edge of the slough.

7 Impcts of Droughts on the Surficil Aquifer System Simulted ground wter level declines fter droughts of 9 nd 8 dys durtion hve similr rel distributions lthough drwdowns re greter nd more extensive fter the 8 dy drought. Drwdowns fter 8 dy drought were lrgest (greter thn 4 ft.) in the undrined northwest portion of the study re nd in the northest re just south of the Loxhtchee River. Drwdowns during drought conditions were lso significnt in the vicinity of wellfields. Drwdowns of over ft. in the Rivier Bech, Royl Plm Bech, Lke Worth, Boynton Bech nd Secost wellfields nd over 3 ft. in the Jupiter nd Secost (Hood Rod) wellfields occurred fter 9 dy drought. Drops of over 3 nd 4 ft. occurred in the sme wellfields fter 8 dy drought. Simulted ground wter flow nd heds long the Intrcostl show high potentil for slt wter intrusion occurring in the southestern corner of the study re est of the Boc Rton Hotel nd Ycht Club nd the Royl Plm Ycht nd Country Club during 9 dy drought with llocted wter use. The intrusion potentil increses during 8 dy drought nd extends one mile further north to include the re est of the Boc Rton Est Wellfield. The simultions lso show high potentil for intrusion occurring est of the Gulfstrem Golf Course during 8 dy drought. The simultions show moderte potentil for slt wter intrusion during 9 dy drought with llocted wter use in the res est of the Boynton Bech Est, the Gulfstrem Golf Course, the Boc Rton Est, the Delry Bech South, nd the Secost North Plm Bech wellfields. The 8 dy drought simultions with llocted wter use show incresed intrusion potentil in these res nd n dditionl re of moderte potentil est of the Boc Teec Corportion, Highlnd Bech, Secost Burm nd Rivier Bech wellfields. Influence of Mintined Surfce Wter Systems on the Surficil Aquifer System Surfce wter systems with mintined wter levels rechrge the quifer system wherever ground wter levels re lower thn the surfce wter levels. Rechrge from these systems keeps ground wter levels severl feet higher thn they would be otherwise in portions of the study re. These systems become prticulrly significnt during droughts when downwrd lekge of surfce wter is the most importnt source of rechrge to the quifer if surfce wter levels cn be mintined. The surfce wter rechrge hs the gretest influence in the vicinity of lrge ground wter withdrwls. With surfce wter rechrge, ground wter levels ner the Boc Rton, Boynton Bech, nd Acme Improvement District wellfields re 3 to 4 ft. higher on verge nd 4 to 6 ft. higher during droughts. Surfce wter rechrge effects re lso notble in the vicinity of the West Plm Bech Wter Ctchment System. When surfce wter levels re mintined in this system, ground wter levels re to 3 ft. higher on verge nd to 6 ft. higher during droughts. Mintined surfce wter systems re generlly considered quite importnt in preventing slt wter intrusion. The model simultions verify tht this is true for certin portions of the study re under drought conditions, however, it is not uniformly true for the entire study re under present conditions. In the northern study re, mintined systems hve no significnt effect on the slt wter intrusion potentil.

8 In the southern study re, the LWDD cnl network does little to reduce slt wter intrusion potentil long the cost north of C-6. However, the network reduces the potentil for slt wter intrusion during the dry seson nd droughts long the cost south of C-6 where rechrge from the cnls rises ground wter levels n verge of bout.9 ft. under dry seson conditions nd bout.5 ft. under 9 dy drought conditions. These increses significntly reduce the potentil for intrusion long most of this stretch lthough there re res where intrusion potentil exists even with the cnl rechrge. Impcts of Buildout Wter Use Ground wter level drwdowns from incresed pumpge t buildout re restricted to the vicinity of the incresed withdrwls. Assuming ll dditionl withdrwls re from the Surficil Aquifer System, projected drwdowns in the study re re lrgest in the north, where the pumpge increses re gretest nd trnsmissivities re low. The lrgest simulted drwdowns, 8 ft., re t the Jupiter nd Secost Hood Rod wellfields. Firly lrge drwdowns, bout 6 ft., re lso projected t the Secost North Plm Bech, nd Burm wellfields. Smller drwdowns, to 4 ft., re projected for the Royl Plm Bech, Lke Worth, Acme, nd the Plm Bech County System wellfields (,, 3, nd 9). Environmentl impcts nd sltwter intrusion potentil were not incresed by the dditionl buildout pumpges except ner the Jupiter nd Secost wellfields. Additionl cumultive withdrwls t the Jupiter nd Secost Hood Rod wellfields cused pproximtely 3 ft. of dditionl drwdown t the northest corner of the Loxhtchee Slough nd 4 ft. of dditionl drwdown t the southest corner. These drwdowns would'be expected to hve dverse impcts on the slough. Incresed potentil for slt wter intrusion occurs est of the Secost North Plm Bech wellfield where simulted heds drop to ft. long the cost s result of the pumpge increses. These drwdowns increse the slt wter intrusion potentil in the re from moderte to probble. Fortuntely, Jupiter lredy plns to shift its dditionl buildout withdrwls to the Floridn quifer which should llow them to meet their demnd without cusing dverse impcts. It ppers tht Secost will need to seek lterntives s well if they re to meet their buildout demnds without environmentl or slt wter intrusion problems. Potentil for Additionl Ground Wter Development Four ctegories of ground wter development potentil - good, moderte, fir, nd poor - were defined bsed on quifer productivity, mbient wter qulity, potentil for wter qulity degrdtion, nd potentil for dverse environmentl impcts. Adverse impcts on existing ground wter users were not considered in defining the ctegories. The Surficil Aquifer System ws divided into res of similr development potentil bsed on these ctegories. The entire upper Floridn quifer ws clssified in the fir potentil development ctegory. The good potentil ground wter development re in estern Plm Bech County occurs entirely within the Biscyne quifer which is the most productive zone of the Surficil Aquifer System. The good re is limited to where the Biscyne is greter thn 4 ft. thick nd where ground wter withdrwls re unlikely to induce sltwter intrusion or cuse dverse environmentl impcts. This re extends north from the Plm Bech - Browrd county line to pproximtely Okeechobee Blvd. vii

9 with n irregulr est - west extent tht generlly includes the re between the Turnpike nd Militry Tril. Most of the rest of the Surficil Aquifer System hs fir or poor development potentil. Ares with moderte development potentil re limited nd occur primrily on the fringes of the good development res. The res with fir development potentil generlly hd low productivity. Further, ground wter from the fir potentil development res of the Surficil Aquifer System west of S.R. 7 nd the West Plm Bech Wter Ctchment re often requires tretment with reverse osmosis to meet potble wter qulity stndrds. Low productivity nd mbient ground wter qulity requiring reverse osmosis lso occur throughout the upper Floridn quifer, ll of which is clssified s hving fir development potentil. Plns for development of these low potentil res will hve to include suitble ground wter tretment. Ares not meeting the criteri for good, moderte or fir were defined s hving poor ground wter development potentil. Ares of the Surficil Aquifer System under the Loxhtchee Slough, the West Plm Bech Wter Ctchment Are, nd the wetlnds djcent to Wter Conservtion Are were clssified in the poor potentil group becuse of environmentl concerns. The Surficil Aquifer System long the costl mrgin is included in the poor ctegory becuse of sltwter intrusion concerns. The lower Floridn quifer is in the poor ctegory becuse it hs very poor qulity mbient ground wter. Recommendtions Additionl Surficil Aquifer System withdrwls should be denied if they re likely to decrese ground wter levels or sewrd ground wter flow long those portions of the cost where the potentil for sltwter intrusion is lredy significnt. Withdrwls which will cuse dditionl drwdowns under the Loxhtchee Slough should lso be denied if the slough is to be protected. Existing permits for ground wter use in these res should continue to be re-evluted nd djusted ccordingly through the SFWMD wter use permitting process. Wter levels in the LWDD costl bsins should continue to be mintined. When surfce wter deliveries to the LWDD system re limited, priority should be given to mintining cnl levels in the costl bsins becuse of their importnce in preventing sltwter intrusion. Additionl ground wter development of the Surficil Aquifer System should be done preferentilly ccording to potentil with res of good, moderte nd fir potentil developed in tht order. The ground wter development potentil of the Floridn Aquifer System in the study re should be explored further to determine if it is vible lterntive to the Surficil Aquifer System. The models developed in this study should continue to be used in the wter use permitting nd plnning process. They should be refined nd updted s dditionl dt become vilble with emphsis on improving confidence in the simultion results. viii

21 ABSTRACT The Surficil Aquifer System is the primry public wter supply source in Estern Plm Bech County (the study re). The extent nd composition of the Surficil Aquifer System nd two zones within it, the highly productive Biscyne quifer nd modertely productive intervl surrounding it, were defined using previously vilble nd newly collected dt. Two three-dimensionl ground wter flow models of the Surficil Aquifer System, one of the northern study re nd one of the southern study re, were developed. The models were used to simulte vriety of meteorologic nd mngement scenrios. Results showed the effects of llocted ground wter use, surfce wter rechrge, droughts nd projected buildout ground wter use on the system. Allocted wter use lowers ground wter levels nd increses the potentil for sltwter intrusion long the cost south of the C-6 cnl. Surfce wter infiltrtion is the primry source of rechrge to the quifer during droughts nd reduces the potentil for costl sltwter intrusion south of C-6 by mintining ground wter levels. However, sltwter intrusion is likely to occur long portions of the Plm Bech County cost during extended droughts. Ground wter from the Surficil Aquifer System should be vilble to meet projected buildout demnds except in the northestern study re where dditionl Surficil Aquifer System withdrwls by the Town of Jupiter nd Secost Utilities would be expected to dversely impct the Loxhtchee Slough. These users will need to seek lterntive sources. Presently llocted withdrwls long the costl mrgin where there is significnt potentil for sltwter intrusion should be reviewed nd moved inlnd where possible. Additionl development of the Surficil Aquifer System should not be permitted in these res. The best potentil for further ground wter development exists in the south centrl portion of estern Plm Bech County where the Biscyne quifer is thick nd dverse environmentl nd wter qulity impcts re not expected.

22 INTRODUCTION PURPOSE AND SCOPE This report presents the results of ground wter resources ssessment of estern Plm Bech County. The loction nd extent of the study re re shown in Figures nd. There re two quifer systems underlying the study re, the shllow Surficil Aquifer System nd the deeper Floridn Aquifer System. Most of this report focuses on the Surficil Aquifer System which is widely used for irrigtion nd public wter supply in the study re. The Floridn Aquifer System, which generlly hs poorer wter qulity nd lower yields thn the Surficil Aquifer System, is covered in less detil since it is infrequently used t present. Mjor tsks within the scope of the ssessment were to: ) Compile nd evlute existing hydrogeologic dt. ) Conduct field investigtions to collect dditionl hydrogeologic dt on the Surficil Aquifer System. 3) Define the hydrogeologic frmework of the Surficil Aquifer System. 4) Develop nd clibrte two, three-dimensionl ground wter flow models of the Surficil Aquifer System, one south nd one north of the C-5 Cnl. 5) Conduct model sensitivity nlyses to determine the reltive influence of different components of the hydrologic nd hydrogeologic regimes. 6) Mke predictive simultions with the models to ssess the potentil impcts of different climtic nd hydrologic conditions on the quifer system. DATA COLLECTION AND ANALYSIS The extent nd chrcteristics of the Surficil Aquifer System were determined bsed on extensive review nd evlution of ll vilble hydrogeologic informtion. This informtion ws obtined from the United Sttes Geologicl Survey (USGS), South Florid Wter Mngement District (SFWMD), nd privte consultnt publictions nd files. These dt were supplemented by field investigtions conducted s prt of this study t five sites in the study re. These investigtions included quifer smple collection, geophysicl logging, nd 48 to 7 hour pump tests with multi-level observtions wells. Dt from more thn 5 wells including vrious combintions of well cuttings, smple descriptions, drilling nd geophysicl logs were reviewed. These dt were rnked ccording to qulity bsed on thoroughness of smple descriptions, vilbility of geophysicl logs, nd the sensitivity of geophysicl logs to known lithologic vritions within the quifer. Low qulity dt were eliminted nd dt from 9 of the 5 wells were used to estblish the extent nd composition of the quifer. The hydrulic chrcteristics of the quifer were determined from the results of 3 pump tests. The pump test dt were reviewed nd renlyzed s necessry to

25 estimte the hydrulic conductivities of zones within the quifer. Renlyses were done with both nlyticl nd numericl techniques. Additionl pump tests in the study re were lso reviewed but were not used becuse of poor dt qulity or lck of documenttion. The Surficil Aquifer System ws divided into two hydrogeologic zones bsed on the well nd pump test dt; highly to modertely trnsmissive production zone exploited by lmost ll ground wter users in the study re, nd less trnsmissive, non-production zone. The production zone ws further divided into highly trnsmissive intervl, which is the northern extent of the Biscyne quifer, nd the remining modertely trnsmissive intervl referred to herein s the non-biscyne production zone. The extent of ech zone in the study re ws mpped by correlting specific geologic fetures observed in well dt to generl hydrulic chrcteristics. GROUND WATER FLOW MODELS (SURFICIAL AQUIFER SYSTEM) After the extent, composition nd hydrulic chrcteristics of the quifer were defined, two ground wter flow models of the Surficil Aquifer System in estern Plm Bech County were developed for the study re using the USGS Modulr Three-Dimensionl Finite-Difference Ground Wter Flow Model (MODFLOW) code. The south model is bounded by C-5 to the north, the Hillsboro cnl to the south, the Intrcostl Wterwy to the est nd Wter Conservtion Are to the west. The north model is bounded by C-5 to the south, the Plm Bech - Mrtin County line to the north, the Intrcostl Wterwy to the est nd the L-8 cnl to the west. The models were set up with uniform one hlf mile rel grids which overlp t the C-5 boundry. Both models re fully three-dimensionl with six lyers. This provides good representtion of the hydrogeologic zones within the quifer nd the prtil penetrtion of cnls nd wells. The quifer ws divided into three hydrulic conductivity zones for modeling purposes; the very high permebility Biscyne quifer, the moderte permebility non-biscyne production zone, nd the low permebility non-production zone. The thickness nd verticl extent of the lyers in ech model were vried to follow the hydrulic conductivity zones. Development of the ground wter flow models required detiled informtion on ground wter withdrwls, rinfll, lnd use nd surfce wter systems. Individul wter use permits were reviewed to determine permitted ground wter withdrwls nd well loctions. Public wter supply ground wter use ws compiled from reported pumpges. Irrigtion wter use ws estimted with the modified Blney Criddle method used in the SFWMD wter use permitting process. Rechrge to the quifer from rinfll infiltrtion ws estimted for the models bsed on observed rinfll nd lnd use dt. Rinfll dt were obtined from SFWMD publictions nd the District's DBHYDRO dtbse. Lnd use dt were provided by the SFWMD Lnd nd Wter Use Plnning Group. Surfce wter systems in the study re were represented in the models bsed on system mps, stge dt, wter level mintennce schedules nd structure control elevtions provided by system opertors, SFWMD permit files nd eril photogrphs. The models were clibrted using four sets of wter level dt collected by the USGS between October 983 nd My 985 t 74 observtion wells in the study re. A stedy stte clibrtion ws mde ginst the verge mesured wter levels in this period using verge rechrge nd dischrge vlues for the period in the models. A trnsient verifiction of the clibrtion results ws ttempted ginst chnges in mesured wter levels during the sme period using monthly time steps in the

26 models with rechrge nd dischrge vried ccordingly. Further clibrtion/verifiction of the models ws not possible due to lck of dditionl regionl wter level dt. After the models were initilly clibrted, sensitivity nlyses of the models were mde by vrying, one t time, the following model prmeters: ) quifer hydrulic conductivities b) storge coefficients c) cnl sediment hydrulic conductivities d) horizontl to verticl hydrulic conductivity nisotropy rtios e) mximum evpotrnspirtion rte f) evpotrnspirtion extinction depth g) percent of rinfll rechrging the quifer Results of the sensitivity simultions were nlyzed to determine the effects of the prmeters on simulted wter levels nd quifer inflow nd outflow. Predictive simultions were mde with the models for vriety of meteorologic nd wter use scenrios including verge nnul wether conditions, dry seson conditions, nd 9 nd 8 dy drought conditions with llocted wter use. Additionl simultions were mde to determine the impcts of llocted wter use, buildout wter use nd surfce wter systems with mintined wter levels on the underlying quifer system. Results of the simultions were evluted to determine the influence of the vrious fctors on quifer wter levels, rechrge nd dischrge nd to identify potentil sltwter intrusion nd wetlnd impct problems.

27 AQUIFER SYSTEMS INTRODUCTION There re two quifer systems underlying Estern Plm Bech County; the shllow, Surficil Aquifer System nd the deeper, Floridn Aquifer System (Plte ). These quifer systems re effectively seprted by the low permebility rocks nd sediments of the Intermedite Confining Unit. The hydrulic properties of both quifers nd the confining unit (quiclude) re dependent on the lithologic nd digenetic chrcteristics of the rock units in which they occur. SURFICIAL AQUIFER SYSTEM Introduction The Surficil Aquifer System is the principl source of potble wter in estern Plm Bech County. The system is effectively unconfined; wter levels within the quifer correspond to the elevtion of the wter tble. Rechrge occurs loclly by wter moving reltively unimpired down through the ubiquitous surfce snds to the wter tble. Severl studies hve investigted the Surficil Aquifer System in Plm Bech County. The most comprehensive work to dte hs been performed by the USGS. Erly work by Prker et l. (955), estblished the hydrogeologic foundtion of southest Florid but limited dt precluded detiled description of the quifer systems in Plm Bech County. Since 955, the USGS, Florid Bureu of Geology (FBOG), SFWMD nd mny privte consultnts hve collected nd published significnt mount of hydrogeologic dt for Plm Bech County. All vilble dt were reviewed for the development of the modeled hydrogeologic frmework of the study re. A complete bibliogrphy of the publictions nd dt sources used to determine hydrogeology is given in Appendix A. Well dt provided the bsic informtion necessry to determine the extent, composition nd hydrulic chrcteristics of the Surficil Aquifer System in the study re. Well cuttings, smple descriptions, drilling logs, geophysicl logs nd pump test dt were used in determining hydrogeology. Dt from over 5 wells were reviewed. Dt from 9 of these wells were ctully used to determine the quifer extent nd construct the hydrogeologic model. Loctions of wells used in this study re shown on Pltes nd. Dt from the remining wells were not used due to redundncy in loction, shllow completion depths, or unrelible documenttion. Dt were rnked from high of 5 to low of ccording to qulity. Qulity rnkings were bsed primrily on thoroughness of smple descriptions, vilbility of geophysicl logs, nd sensitivity of geophysicl logs to known lithologic vritions within the quifer. Well depths, loctions nd dt qulity rnkings re presented in the hydrogeologic dt in Appendix B, Tbles B- through B-7.

28 Lithology nd Strtigrphy The Surficil Aquifer System in the study re is mde up of severl different strtigrphic units (Plte ). Due to similrities in lithology nd funl ssemblges most of these units hve not been definitively correlted cross the study re. The delinetion nd correltion of these units ws beyond the scope of this study. Previous uthors (Lnd, Rodis nd Schneider, 97) hve dted the rocks nd sediments of the Surficil Aquifer System from Miocene to Pleistocene in ge. However, dt collected in this study support more restricted extent for the Surficil Aquifer System s presented by Miller (987). Miller's lithologic cross-sections throughout the county suggest tht the Surficil Aquifer System is composed of units which rnge in ge from Pliocene (Tmimi Formtion) to Pleistocene (Pmlico Formtion). As shown on Plte, the Surficil Aquifer System in the study re is comprised of prt or ll of the following formtions: Pmlico Formtion (Pleistocene), Anstsi Formtion (Pleistocene), Fort Thompson Formtion (Pleistocene), Clooshtchee Formtion (Pliocene- Pleistocene) nd the Tmimi Formtion (Pliocene). Although Miller (987) includes sediments of the Mimi Oolite (Pleistocene) into the Surficil Aquifer System in Plm Bech County, the extension of this formtion from Browrd County into southestern Plm Bech County is questionble. Investigtions of the strtigrphy of northern Browrd County (Cusrs, 985) nd the Hillsboro Cnl re of southestern Plm Bech County (McCoy nd Hrdee, 97) do not recognize Mimi Oolite sediments in the study re. Therefore, the Mimi Oolite is not included into the Surficil Aquifer System in this study. Pmlico Formtion The Pmlico Formtion in Florid ws identified by Prker nd Cooke (944) bsed on Stephenson's (9) description of the Pleistocene snds of the Pmlico type section in North Crolin. Prker nd Cook pplied the formtion nme to ll Pleistocene mrine deposits in Florid which re younger thn the Anstsi. It is probble tht these snds represent undifferentited deposits from more thn one depositionl environment nd more thn one episode of se level rise nd retret (Enos nd Perkins, 977). The upper portion of the Surficil Aquifer System is comprised primrily of qurtz snds of the Pmlico Formtion. The Pmlico occurs t or ner the surfce throughout most of the study re. Shell is often found in the Pmlico nd my occur in bedded lyers or disseminted throughout the snd. Other less common constituents include silts, clys nd orgnic debris. Recently deposited orgnic soils my cover Pmlico snds in wetlnds or in res where plnt growth hs been persistent. Anstsi Formtion The nme Anstsi Formtion ws proposed by Sellrds (9) for extensive deposits of coquin rock occurring on Anstsi Islnd, Florid nd extending long the est cost. Cook nd Mossom (99) expnded this definition to include " ll the mrine deposits of Pleistocene ge tht underlie the lowest plin (Pmlico Terrce) bordering the est cost of Florid north of the southern prt of Plm Bech County."

29 Within the study re, the Anstsi Formtion vries in composition from pure coquin to mixtures of snd, sndy limestone, sndstone, nd shell. Lterl chnges in lithology re difficult to predict while verticl chnges in lithology tend to follow downwrd progression from unconsolidted snd nd shell to clcreous sndstone to biogenic limestone nd coquin. Solution cvities re common in the limestone nd coquin-dominted intervls. These solutioned zones form some of the most productive intervls of the Surficil Aquifer System. The upper prt of the Anstsi Formtion is contemporneous with the Mimi Oolite. The contct between these two formtions is grdtionl nd occurs ner the Plm Bech/Browrd county border. The lower prt of the Anstsi is contemporneous with the Fort Thompson Formtion. This contct is lso grdtionl nd occurs in the south nd western prt of the study re. Fort Thompson Formtion The Fort Thompson ws the nme proposed by Sellrds (99) for "... deposits consisting of lternting fresh- nd brckish-wter nd mrine mrls nd limestones..." locted long the Clooshtchee River t Fort Thompson. The Fort Thompson Formtion is present in the south nd western prt of the study re. To the est, the Fort Thompson grdes lterlly into the Anstsi Formtion. In the study re Fort Thompson sediments often grde verticlly into the underlying sediments of the Tmimi or Clooshtchee formtions. Clooshtchee Formtion Dll (887) considered the lower shell beds exposed long the upper portion of the Clooshtchee River to be Pliocene in ge; he clled them the Clooshtchee beds or mrls. The formtion ws officilly nmed the Clooshtchee Mrl by Mtson nd Clp (99). DuBr (958) redefined the ge of the Clooshtchee Formtion s being Pleistocene bsed on the occurrence of certin vertebrte fossils. Creful reevlution of invertebrte funl ssemblges hs led more recent uthors (Brooks, 968; Enos nd Perkins, 977) to divide the Formtion into both Pliocene nd Pleistocene members or chronostrtigrphic zones. The Clooshtchee Formtion in the study re consists of sndy, shelly mrls with occsionl stringers of well consolidted sndy limestone. The Formtion is restricted to the western prt of the study re where it my directly underlie the Anstsi, Fort Thompson, or Pmlico formtions. Tmimi Formtion The nme Tmimi Limestone ws proposed by Mnsfield (939) for " limestone penetrted in digging shllow ditches to form the rod bed of the Tmimi Tril over distnce of bout 34 miles in Collier nd Monroe Counties, Florid...The mtrix of the limestone consists of dirty - white to grey, rther hrd, porous, nonoolitic limestone with inclusions of cler qurtz grins". Mnsfield believed the formtion ws Miocene in ge bsed on funl ssemblges. Since Mnsfield's time, mny uthors hve redescribed, recorrelted nd redted the Tmimi Formtion (Prker, 94; 95; Prker nd Cooke, 944; Brooks, 968; 98; Hunter nd Wise, 98). Only Cusrs (985) hs ttempted to correlte the Tmimi Formtion into the study re. In her comprehensive crosssections through Browrd County, Cusrs shows both shelly limestone nd

30 shelly snd fcies of the Tmimi Formtion underlying the Anstsi Formtion in the southest corner of Plm Bech County, ner the Browrd County border. The Tmimi in estern Plm Bech County my be represented by Pliocene ge ptch reef deposits which re remnnts of the northestern extension of the Floridin pseudotoll (Petuch, 986). These pleo-reef trcts nd their ssocited tlus deposits were subject to extensive solutioning during se level declines during the lte Pliocene/erly Pleistocene. The resulting permebility increses in these sediments mke them some of the more productive in the Surficil Aquifer System. Pliocene reef fossils collected from test wells drilled by Swyze nd Kne (in press) nd from wells drilled by SFWMD during the course of this study re identifible s Buckinghm fun (Petuch, 988, personl communiction). In this study, the Buckinghm is considered to be the lower limestone member of the Pliocene Tmimi Formtion, however, some debte currently exists in the literture s to whether the Buckinghm should hve formtion (Mnsfield, 939; Petuch, 986) or member (Hunter nd Wise, 98) sttus. Hydrogeology Introduction The Surficil Aquifer System is the source of most potble wter used in estern Plm Bech County. It is n unconfined quifer rechrged by rin nd lekge from surfce wter bodies with wter level elevtions higher thn the locl wter tble. The Surficil Aquifer System is comprised of the sturted rock nd sediment from the wter tble down to the reltively impermeble silts nd clys of the underlying Intermedite Confining Unit. Becuse the wter tble in Estern Plm Bech County fluctutes sesonlly nd is often t or ner lnd surfce, the vdose zone nd tension-sturted zone sediments re lso included in the quifer system in this study. The bse of the quifer system ws chosen to correspond to the first continuous occurrence of sediments hving estimted hydrulic conductivities less thn 5 feet per dy or cly nd silt constituents in concentrtions greter thn 5%. The Surficil Aquifer System underlies ll of the study re. In generl, the thickness of the system rnges from minimum of 5 feet in the west to mximum of over 4 feet in the est (Plte 3). The thickness my vry loclly s the quifer system bottom tends to reflect the Miocene erosionl surfce which mrks the top of the Hwthorn Group (Plte 4). The Surficil Aquifer System is heterogeneous. In this study the quifer system ws divided into two hydrogeologic zones; highly to modertely trnsmissive production zone exploited by lmost ll of the ground wter users in the study re, nd less trnsmissive, non-production zone. The production zone ws further divided into highly trnsmissive intervl, which is the northern extension of the Biscyne quifer, nd modertely trnsmissive intervl, herefter referred to s the non-biscyne production zone (Figure 3). Individul zones nd the Biscyne quifer were identified in wells by correlting specific digenetic fetures to generl hydrulic chrcteristics. Tops, bottoms, nd thickness of both zones nd the Biscyne quifer re listed in Appendix B, Tbles B- through B-5.

32 Dt Anlysis Hydrulic chrcteristics of the Surficil Aquifer System were determined from dt cquired from 3 quifer performnce tests (APTs). The loctions of these APTs re shown on Plte 5. Other APTs performed in the study re were nlyzed but were not used due to the poor qulity of dt or lck of documenttion. Four of the APTs used were performed by the South Florid Wter Mngement District. Fourteen others were performed by the USGS. Of these fourteen, four tests were repeted by the South Florid Wter Mngement District fter dditionl observtion wells were dded t the sites. The reminder of the APT dt ws provided by privte consultnts from tests performed in conjunction with wellfield expnsion progrms or djcent user impct studies. Results of the renlyses of dt from these tests re shown in Tbles,, nd 3. The methods used to nlyze individul test dt re noted in Tble. Trnsmissivity estimtes were commonly mde using the Jcob method (Cooper nd Jcob, 946), since the Jcob method is less subjective thn curve mtching techniques when smll fluctutions re present in the erly time recorded dt. In cses where the ssumptions of the Jcob method were not met, curve mtching techniques described by Boulton, (963), Wlton (97), Hntush (964), or Neumn (975) were used. Hydrulic conductivity vlues were estimted by dividing the clculted trnsmissivity by the thickness of the hydruliclly dominnt zone s determined from drilling logs nd smple descriptions. Conductivity estimtes were mde for the Biscyne quifer nd the non-biscyne production zone using APT dt from sites where these zones controlled locl quifer chrcteristics. Using the method described bove the verge hydrulic conductivity vlue of the Biscyne quifer, ws estimted to be 6 ft/dy while the verge hydrulic conductivity of the non-biscyne production zone ws estimted to be 5 ft/dy. Good published dt for determining the hydrulic chrcteristics of the nonproduction zone surfce snds were not vilble. Prker et l. (955) found hydrulic conductivities of snds in estern Plm Bech county to rnge from.3 to 7 ft/dy. Constnt hed permebility tests performed with K-65 permemeter on shllow sediments t the West Plm Bech Post Office exfiltrtion study site show hydrulic conductivities to be bout 5 ft/dy (Jos6 Alvrez, SFWMD, personl communiction, 3/88). This 5 ft/dy vlue is considered to be resonble estimtion of the verge hydrulic conductivity of the non-production zone sediments. The specific yield of the shllow snds of the Surficil Aquifer System hs not been relibly determined from APT dt. APTs performed in res where zones of high trnsmissivity re present must be run for extremely long periods of time before the ctul dewtering of the surfce sediments occurs. All of the APT dt used in this report yielded stortivity vlues indictive of erly time fluid depressuriztion effects. Prker et l. (955) estimted the specific yield of surfce snds in Mimi, Florid by mesuring the rise in wter levels in 9 foot deep monitor well (G-86) cused by locl rinfll. The fine to medium qurtz snds penetrted by this well re very similr to the shllow sediments in Plm Bech County. The uthors clculted

They speculted tht these vlues were probbly greter thn the specific yield since some of this wter would be retined by cpillry forces during grvity dringe. Johnson (967) compiled specific yield vlues bsed on lbortory nlyses for clstic sediments rnging from cly to corse grvel. His findings showed specific yields for fine to corse snd rnged from. to.35. The verge specific yields for the fine, medium nd corse snds described in Johnson's report were.,.6, nd.3 respectively. An verge specific yield vlue of.5 ws ssumed for the ner surfce sediments in the study re bsed on their similrities to the sediments described by Prker et l. (955) nd Johnson (967) nd on the model clibrtion results. Further discussion of the effects of specific yield on wter levels is presented in the Ground Wter Modeling section of this report. Within ech zone of the Surficil Aquifer System the rtio of verticl to horizontl conductivity (nisotropy rtio) is low. Previous uthors (Johnson nd Morris, 96; Dvis, 969; Piersol et l., 94) hve shown tht in structurlly undisturbed sedimentry formtions this rtio is typiclly less thn one. In the elstic intervls of the Surficil Aquifer System of estern Plm Bech County nisotropy vlues less thn one re expected due to the hydrulic influences of smll scle strtifying fetures such s grin shpe, orienttion, sorting, bedding contcts nd unconformities. The gross effect of this strtifiction is tht the effective verticl conductivity of section of the quifer cn be low even in zones where horizontl conductivities re high. Crbonte dominted intervls of the Surficil Aquifer System lso pper to be hydruliclly strtified. Solution cvities observed in dul tube cuttings of Biscyne strt usully hd horizontl mjor xis of solutioning which suggests tht in these zones horizontl hydrulic conductivities re much higher thn verticl hydrulic conductivities. Very low verticl to horizontl nisotropy rtios (much less thn.) in the Surficil Aquifer System in the study re re ssocited with the presence of cly or mrl lenses. These lenses cn impede the verticl movement of wter to the extent tht the system will ct s leky, semi-confined quifer. Well dt showed these lenses to be loclized fetures of limited rel extent. The Biscyne Aquifer The Biscyne quifer is the most productive intervl within the Surficil Aquifer System in Plm Bech County. The Biscyne quifer is chrcterized by highly solutioned limestones with hydrulic conductivities s high s 4, ft/dy (Tble 3). Lrge dimeter wells completed in these limestones my produce s much s, gllons per minute; consequently, the Biscyne quifer hs excellent potentil for wter supply development. The nme Biscyne quifer ws proposed by Prker (95) for the hydrogeologic unit of wter-bering rocks tht crries unconfined ground wter in southestern Florid. This definition hs been refined by subsequent uthors (Schroeder, Klein, nd Hoy, 958; Klein nd Hull, 978) to include generl hydrulic

37 properties. Fish (988) hs recently proposed definition of the Biscyne quifer in Browrd County bsed on the strtigrphy nd hydrulic conductivity of the Surficil Aquifer System there. While Fish's definition is the most detiled to dte, it is not pplicble in the study re becuse it is dependent on regionl strtigrphic correltions which hve not been done in Plm Bech County. The Biscyne quifer in estern Plm Bech County ws defined in this study s the intervl within the Surficil Aquifer System which: ) is comprised of t lest 5 percent highly permeble (estimted hydrulic conductivity t lest 5 ft./dy) strt, ) is t lest feet thick, nd 3) extends from the top of the shllowest lterlly-continuous highly permeble strt to the bse of the deepest highly permeble strt which my be included without violting criteri ). Other investigtions in the study re hve clled it the "cvity riddled zone" (Lnd, 977), the "cvity zone" (Fisher, 98) nd the "zone of secondry permebility" (Swyze nd Miller, 984). Dt from these erlier investigtions were used in conjunction with drilling nd APT dt collected during this study to correlte the Biscyne quifer in estern Plm Bech County. Mps of Biscyne quifer thickness, top elevtion nd bottom elevtion re shown on Pltes 6, 7, nd 8. Biscyne quifer strt is principlly composed of highly solutioned crbonte deposits. Mny of these deposits re biogenic in nture. Reefl fun is common suggesting tht in some res the :high degree of dissolutioning my be ssocited with the occurrence of primry porosity development in reef nd tlus deposits (Petuch 986; Miller, 988 ). The highest hydrulic conductivities occur in intervls where the gretest mount of crbonte cement nd/or llochems hve been removed. Intervls where the originl rock ws prtilly grin supported by silicious snd does not disply high hydrulic conductivities even though most or ll of the originl crbonte cement hs dissolved. Only intervls chrcterized by empty or nerly empty solution cvities were recognized s Biscyne quifer strt. The following drilling chrcteristics nd digenetic fetures displyed in well cuttings were used to determine the presence of the Biscyne quifer in res where APT dt were unvilble: ) lrge circultion losses nd/or sudden drops in the drill string during mud rotry drilling in crbonte intervls, ) the presence of crbonte cemented cuttings with interconnected vugs or cvities, 3) concretion shped cuttings in predominntly crbonte intervls, nd 4) irregulrly shped crbonte cuttings with sucrosic texture. The occurrence of clcite crystls in well cuttings ws not considered conclusive evidence of Biscyne strt s crystlline clcite ws more commonly found in modertely permeble intervls s pseudomorphs of mollusks. Production Zone Throughout most of the Surficil Aquifer System the Biscyne quifer is surrounded by modertely trnsmissive zone of sndy shell, modertely solutioned limestone or modertely to well solutioned sndstone. In this study, the Biscyne quifer nd the modertely trnsmissive zone re referred to collectively s the "production zone". Its thickness nd depth below lnd surfce in the northern prt of the study re re shown on Pltes 9,, nd. The production zone ws not mpped in the southern prt of the study re, becuse the Biscyne quifer is the dominnt ground wter bering intervl in this region. In the centrl nd northern

38 prt of the county the non-biscyne production zone sediments hve hydrulic conductivities verging pproximtely 5 ftjdy. Non-Production Zone Sediments The non-production zone sediments re composed of low to modertely permeble snds nd mrls with scttered lenses of very low permebility cly nd limonite-cemented sndstones loclly clled "hrdpn". Non-production zone sediments typiclly correspond to the snds of the Pmlico nd Anstsi formtions or the mrls of the Clooshtchee Formtion. Hydrulic chrcteristics of nonproduction zone sediments were discussed previously in the Dt Anlysis section. Thin discontinuous low permebility zones of cly or sndstone were identified in some wells. These low permebility zones were not incorported into the hydrogeologic model since their discontinuous nture precludes their hving significnt effect on regionl hydrulics. Appendix B, Tbles B-6 nd B-7 describes the depth nd occurrence of these intervls for individuls wishing to investigte specific sites in more detil. Wter Qulity Surficil Aquifer System ground wter qulity vries with loction nd depth in the study re. The wter qulity is influenced by numerous fctors including the composition nd permebility of the quifer mterils, locl hydrologic conditions, sltwter intrusion nd contmintion from mn's ctivities. In most of the study re, the ground wter either meets or cn be treted with conventionl methods to meet potble wter stndrds. Exceptions occur primrily where sltwter intrusion hs occurred long the cost nd where residul connte wter occurs in the west. Wter qulity trends in the Surficil Aquifer System follow the physiogrphic trends in the study re. The three physiogrphic regions of estern Plm Bech County, the costl ridge, the sndy fltlnds, nd the Evergldes, (Prker nd Cooke, 944) re shown in Figure 4. Ground wter qulity is generlly good in the costl ridge, good to poor in the sndy fltlnds, nd poor in the Evergldes. Ground wter qulity in the study re is best in the costl ridge nd djcent sndy fltlnds where the Biscyne quifer is present. The high permebilities of the Biscyne strt in these res hve fcilitted the flushing of residul sewter by better qulity rinfll nd cnl infiltrtion rechrge wter. Wter qulity in the Biscyne quifer is of the clcium bicrbonte type s result of limestone dissolution. The mbient ground wter is potble with respect to chlorides nd totl dissolved solids except where sltwter intrusion hs occurred long the costl mrgins. In the western sndy fltlnds nd Evergldes, where quifer permebilities re low, flushing of residul sewter is incomplete nd the ground wter qulity is poor. Ground wter qulity in these res deteriortes with depth s result of even poorer flushing due to lower permebilities towrd the bse of the quifer. Chloride nd totl dissolved solids concentrtions in these res often exceed potble stndrds. Chloride nd specific conductnce dt collected in 987 for the Surficil Aquifer System re given in Appendix D. These prmeters re indictive of the degree of ground wter minerliztion nd the mbient wter qulity of the quifer

Loctions of wter qulity wells re plotted on Plte nd verge mesured chloride vlues in 987 re plotted on Plte 3. Sltwter intrusion hs occurred long much of the costl mrgin of the Surficil Aquifer System. The intrusion results from combintion of fctors. Lrge scle withdrwls from the Surficil Aquifer System, extensive dringe systems nd incresed impervious re hve reduced rechrge, lowered wter levels, nd diminished the originl sewrd hydrulic grdient in some res. In ddition, numerous smll cnls without slinity control structures hve been dredged into the Intrcostl Wterwy creting inlnd fingers of brckish wter. Sltwter intrusion ner or into costl wellfields due to lrge ground wter withdrwls hs cused severl mjor public wter supply opertors to chnge their wellfield operting procedures. Highlnd Bech, Boc Rton, Delry Bech nd Boynton Bech wter supply systems hve ll limited or eliminted pumping from their esternmost wells due to incresing chloride concentrtions. Jupiter nd Tequest hve both begun to rely on ground wter withdrwls from Jupiter's newer, inlnd wells due to sltwter intrusion from the Atlntic Ocen, the Intrcostl Wterwy nd the brckish reches of the Loxhtchee River. The SFWMD oversees the SALT (Slt Wter Trcking) network of public, USGS nd privte wells. District stff require the implementtion of SALT progrm in wter use res where historiclly high chloride concentrtions exist. Dt from SALT wells re used by the District in both plnning nd regulting wter use with the objective of verting or minimizing sltwter intrusion into the Surficil Aquifer System. INTERMEDIATE CONFINING UNIT Introduction The Intermedite Confining Unit in the study re is comprised of the reltively impermeble sequence of clys, silts nd limestones of the Hwthorn Group. The Hwthorn Group described in this study includes n upper Miocene fine clstic fcies which my be time equivlent to the Tmimi Formtion s described by Mnsfield (939). Within the study re this confining unit vries in thickness from over 5 feet to over 7 feet nd effectively restricts verticl movement of wter between the confined Floridn Aquifer System nd the Surficil Aquifer System. The top of this unit occurs t depths below -5 feet NGVD in the western prt of the study re nd dips towrd the cost. In the southestern prt of the county, the top of the unit occurs t depths below -4 feet NGVD. Lithology nd Strtigrphy Tmimi Formtion As discussed previously, no definitive correltion of the Tmimi Formtion hs been mde through estern Plm Bech County. Beds of clcreous sndstone nd sndy limestone which occur beneth the Anstsi Formtion in the southern prt of the study re (Cusrs, 985) my be time equivlent to the Buckinghm Member of the Tmimi Formtion. Buckinghm strt is included in the Surficil Aquifer System.

41 This study follows Scott's (988) proposl tht siliciclstic sediments previously ssigned to the lower Tmimi Formtion be ressigned to his newly proposed Pece River Formtion of the Hwthorn Group. Cusrs (985), identified these sediments in south Plm Bech County s undifferentited Tmimi nd Hwthorn. These sediments re reltively impermeble in the study re, nd their occurrence typiclly mrks the top of the Intermedite Confining Unit. Hwthorn Group Phosphtic sediments qurried t the Simmons pits ner the town of Hwthorn, Alchu County, Florid, were given the nme "Hwthorn Beds" by Dll nd Hrris (89). Mtson nd Clp (99) gve the unit formtion sttus bsed on descriptions by Dll nd Hrris (89) nd Johnson (888). Puri nd Vernon (964) designted the Devil's Mill Hopper nd Brooks Sink exposures s the type loctions for the Hwthorn Formtion. Scott (988) formlly elevted the formtion to Group sttus nd proposed tht the Hwthorn # core W-486, drilled in the vicinity of the now inccessible Simmons pit, be designted s the neostrtotype or replcement type section for the Hwthorn Group. A comprehensive tretise of the lithostrtigrphy of the Hwthorn Group including review of previous investigtions is presented by Scott (988). Only the upper sediments of the Hwthorn Group were encountered in the test wells drilled in this study. Descriptions of the deeper Hwthorn sediments were compiled from consultnt reports documenting the drilling nd construction of the wells shown on Plte 4 which penetrte through the Hwthorn Group. In the study re, sediments of the upper Hwthorn Group re sndy, clyey, clcreous, phosphtic, very fine to fine grined nd poorly indurted. Scott (988) plces these sediments into his newly proposed Pece River Formtion. The cly content of these sediments typiclly increse with depth until the unit becomes dominted by sndy, plstic, olive gry cly. Thin beds of silty snd nd shell re lso found in this clyey intervl. Smples from wells in estern Plm Bech County show rpid chnge from cly to mrl nd limestone dominted, Miocene strt underlying the Pece River Formtion. Previous studies hve identified this crbonte intervl s the Tmp Formtion (Gerghty & Miller, 986, 987, 987b; CHM Hill, 986). Bsed on King (979) nd King nd Wright's (979) redesigntion of the Tmp type section, Scott (988) mpped the top of the thickness of Tmp sediments nd showed their occurrence is restricted to west-centrl Florid. Scott (988) proposed tht the Tmp Formtion be downgrded to member sttus due to its limited occurrence. He further proposed tht ll the Miocene crbonte section underlying the Pece River Formtion in south Florid be ssigned to the newly nmed Arcdi Formtion of the Hwthorn Group. Hydrogeology The reltively impermeble clys nd fine clstic sediments of the Pece River Formtion nd the clys nd limestones of the underlying Arcdi Formtion prevent movement of wter between the Surficil Aquifer System nd the Floridn Aquifer System. A producing zone my be present in the bsl limestones of the Arcdi Formtion (identified s Tmp Formtion by Gerghty nd Miller, 988).

42 Hydrulic chrcteristics of this zone nd its degree of connection with the upper producing zones of the Floridn Aquifer System hve not been determined. FLORIDAN AQUIFER SYSTEM Introduction The Floridn Aquifer System is composed of thick sequence of limestones nd dolomites. The system is confined bove by the Intermedite Confining Unit nd below by the thick nhydrite sequences of the Sub-Floridn Confining Unit (Plte ). Good producing zones occur in both the upper nd lower portions of the Floridn Aquifer System. The producing zones of the upper prt of the system re seprted from those of the lower prt of the system by thick intr-quifer confining unit of dense limestone nd dolomite. The well-confined nture of Floridn strt in the study re precludes the possibility of wter either entering or leving the system except through wells or lterl ground wter flow. Geologicl nd hydrulic dt on the Floridn Aquifer System in Plm Bech County is limited nd detiled mps of the system re not vilble. Informtion on the Floridn Aquifer System presented in this study comes from work performed by the USGS, FBOG, SFWMD, nd from consultnt reports documenting the construction of the injection nd reverse osmosis wells shown on Plte 4. The correltion nd mpping of the system ws beyond the scope of this study. Floridn Aquifer System wter in the study re is non-potble without tretment. Wter qulity generlly becomes poorer with depth. In the northern prt of the study re wter from the upper zones of the Floridn Aquifer System is of sufficient qulity to mke desliniztion for wter supply vible. In contrst, dissolved solids concentrtions in wter in the lower producing zones of the system re so high tht it cnnot presently be economiclly treted to meet potble wter stndrds. Lithology nd Strtigrghy Erly work by Prker (955) describes the "Floridn quifer" s the hydrologic unit including "prts or ll of the middle Eocene (Avon Prk nd Lke City limestones), upper Eocene (Ocl Limestone), Oligocene (Suwnnee Limestone), nd Miocene (Tmp Limestone), nd permeble prts of the Hwthorn formtion tht re in hydrologic contct with the rest of the quifer". In 986, the Florid Geologicl Survey Comminuttee on Florid Hydrostrtigrphic Unit Definition elected to replce the term "Floridn quifer" with "Floridn quifer system" in recognition of the mny producing zones within this hydrogeologic unit (Florid Bureu of Geology, 986). In ddition, the committee formlized the inclusion of the Oldsmr Formtion (Eocene) nd prts of the Cedr Keys Formtion (Pleocene) into the totl hydrogeologic frmework of the Floridn Aquifer System. Rock units which mke up the system in the study re re the Suwnnee Formtion, the Ocl Group, the Avon Prk Formtion, the Lke City Formtion, the Oldsmr Formtion, nd the upper prt of the Cedr Keys Formtion (Plte ). Suwnnee Limestone Applin nd Applin (944) show undifferentited Oligocene beds extending throughout Plm Bech County. While ttempts hve been mde to correlte the

43 Suwnnee cross the estern prt of the county (CHM Hill, 987), problems verifying the occurrence of this formtion still exist due to the lck of good index fossil smples nd the inconsistent lithology of the rocks nd sediments directly overlying the Ocl. The Suwnnee Limestone is often good producing zone in res where it overlies the Ocl. In the study re, Oligocene ge rocks nd sediments, which some uthors hve clled the Suwnnee Formtion, re high in their elstic composition. This clstic constituent of the formtion hs inhibited solutioning of the strt, resulting in only modertely good production from this prt of the Floridn Aquifer System. Ocl Group Nomenclture of the upper Eocene limestones in Florid hs evolved with the work of severl uthors (Cook, 945; Applin nd Applin, 944; Vernon, 95). Puri (957) proposed tht these limestones; the Crystl River, Williston nd Inglis Formtions; be recognized collectively s the Ocl Group. Becuse lterl grdtions in lithology often mke differentition between these formtions difficult they re commonly referred to collectively by their group nme, the Ocl. In estern Plm Bech County the Ocl Group is composed of very ple ornge to yellowish gry, highly fossiliferous, sprry limestone. The limestone is vuggy in some intervls indicting solutioning. The top of the Ocl is n erosionl surfce nd occurs between -9 nd - ft. NGVD where the Ocl is present. Smples from Acme nd Plm Bech County System 9 injection wells show the Ocl hs been completely eroded nd is not present in these res. In most res of the Stte, the Ocl Group is the principl producing unit of the Floridn Aquifer System. However, testing performed t the Jupiter RO- production well shows tht Ocl strt contributes only one qurter of the nturlly flowing wter from the upper prt of the system. Further evlution of this unit in other prts of the study re will hve to be performed before its regionl production potentil cn be determined. Avon Prk Limestone The nme Avon Prk Limestone ws proposed by Applin nd Applin (944) for n Eocene limestone encountered in well t the Avon Prk Bombing Rnge in Polk County, Florid. Surfce exposures of the Avon Prk occur in Citrus nd Levy Counties nd in severl loclities long the defunct Cross Stte Florid Brge Cnl. The Avon Prk is composed of yellowish gry to drk gry, fossiliferous, grnulr to chlky limestone with occsionl dolomitic intervls. In the study re the top of the Avon Prk occurs t depths rnging from - NGVD to greter thn -4 NGVD. Thicknesses of the Avon Prk vry from 5 to over 7 feet. Locl trends in dip re difficult to determine becuse of problems in differentiting the limestones of the Avon Prk from the limestones of overlying formtions. Smple logs of injection wells indicte the presence of severl permeble zones within the Avon Prk. There is insufficient dt vilble to correlte nd mp these zones t present.

44 Lke City Limestone The Lke City Limestone ws described by Applin nd Applin (944) s n Eocene ge, chlky fossiliferous limestone with beds of drk brown dolomite occurring between -49 nd - feet in well t Lke City, Columbi County, Florid. In the study re the top of this formtion occurs from bout -35 to greter thn -9 feet NGVD. The Lke City ppers to dip nd thicken to the est. Totl thickness my exceed 5 feet ner the cost. The lithology of the Lke City in the study re is similr to tht described by Applin nd Applin (944). The limestones nd dolomites of the Lke City re dense nd reltively impermeble. These crbontes mke up the mjor intr-quifer confining zone within the Floridn Aquifer System. Smples nd cores from deep Floridn wells indicte tht within the study re Lke City strt effectively prevents the mixing of wters from the upper nd lower producing zones of the Floridn Aquifer System. Oldsmr Limestone The Oldsmr Limestone ws the nme proposed by Applin nd Applin (944) for n erly Eocene limestone in n oil test well ner Oldsmr, Hillsborough County, Florid. In the study re the top of the Oldsmr rnges from less then - feet NGVD in Southern Sttes No. to greter thn -9 feet NGVD in the Plm Bech County System 9 injection well. The Oldsmr ppers to hve locl dip to the est-southest. The Oldsmr grdes upwrd from yellowish brown, crystlline, mssive frctured nd solutioned dolomite to pinkish gry / very ple ornge, sprry, biogenic, limestone. The dolomites in the lower section re often highly cvernous due to dissolutioning. Drillers in south Florid hve unofficilly nmed these solutioned dolomites of the Oldsmr nd Upper Cedr Keys formtions the " Boulder Zone " (Plte ) due to the wy the drilling of this intervl resembles drilling lyer of loose, boulder size rocks. In Plm Bech County, these solutioned zones often hve extremely high hydrulic conductivities. This intervl occurs loclly between -7 nd -3 feet NGVD nd is currently exploited by ll of the eight ctive Clss I injection wells in the study re. Cedr Keys Limestone '"The nme Cedr Keys Formtion ws proposed by Cole (944) for limestone of Pleocene ge in deep oil test t Cedr Keys, Florid.", (Stringfield, 966). The top of the Formtion probbly occurs t bout -3 ft NGVD in the deep oil explortion well Southern Sttes No.. The Formtion dips to the southest nd probbly occurs t depths greter thn -36 ft NGVD ner the cost. The lithology of the Cedr Keys Limestone rnges from white cremy limestone to frctured nd cvernous gry to brown dolomite. Evporites re common in the lower prt of the Cedr Keys. Becuse the incresing presence of these continuous, unsolutioned evporite lyers indictes the bsence of ctive wter movement, the beginning of this evporite sequence hs been designted the top of the sub-floridn Confining Unit (FBOG, 986).

45 The upper section of the Cedr Keys Limestone is often frctured nd cvernous. It usully hs good hydrulic connection with the overlying Oldsmr Limestone. In other res of the stte this upper section is exploited s n injection zone for liquid wste disposl due to its poor qulity wter nd very high hydrulic conductivity. Hydrogeology The Floridn Aquifer System is confined rtesin system. Potentiometric surfces of the system in estern Plm Bech County my exceed ground level by s much s 3 ft. (Gerghty nd Miller, 988). Wells completed in the Floridn Aquifer System will flow unided t lnd surfce. Hydrulic properties of the Floridn Aquifer System vry both verticlly nd horizontlly. Good producing zones exist in both the upper nd lower portions of the system where post-depositionl processes such s frcturing, solutioning nd dolomitiztion hve enhnced permebility. The intermedite section of the system is reltively impermeble nd cts s n intr-quifer confining unit. Throughout the Stte the permeble zones in the upper prt of the Floridn Aquifer System occur where solutioning hs been gretest. Solutioning occurs where slightly cidic rechrge wter comes into contct with the crbontes of the system. Frctures in upper Floridn Aquifer System strt fcilitte solutioning by exposing more crbonte surfce re to cidic wters nd providing pssgewys for wter movement. Formtion contcts in the upper prt of the system re lso typiclly sites of solutioning. Severl producing zones hve been correlted in the upper prt of the Floridn Aquifer System in counties djcent to nd north of the study re (Shw nd Trost, 984) nd (Brown nd Reese, 979). Although individul zones pper to hve unique potentiometric surfces (Brown nd Reese, 979) some of these zones my be hydruliclly connected. The producing zones mpped by Brown nd Reese hve not been correlted through Plm Bech County, nd the current pucity of dt precludes their delinetion in this study. Shw nd Trost (984) show tht trnsmissivities in the upper producing zones of the Floridn Aquifer System decrese southwrd nd estwrd of Polk County. The upper producing zones of the Floridn in north Plm Bech County re only modertely solutioned nd hve trnsmissivities of less thn, ft. /dy (Gerghty nd Miller, 988). Wter in the upper producing zones of the Floridn Aquifer System in the study re comes from two sources, wter flowing in from rechrge res outside the study re nd relict se wter. Inflowing wter is the most significnt source of rechrge to these upper zones. The process of inflow into the upper producing zones is ultimtely driven by rinfll in Floridn rechrge res in northern Polk County where the Intermedite Confining Unit is thin or bsent (Stringfield, 936; Stewrt, 98). Rinfll in these res percoltes down into the upper prt of the system, then flows lterlly in ll directions. As it moves, the fresh wter rects with the minerls in the strt nd mixes with relict sewter not yet flushed from the mrine limestone producing zones. By the time it reches Plm Bech County, dissolved solid nd chloride

46 concentrtions in the wter exceed potble stndrds. From Plm Bech County, flow in the upper Floridn continues to move south nd est until it is dischrged through wells or nturl spring in the ocen floor. In the lower zones of the Floridn Aquifer System, post-depositionl porosity development due to frcturing nd solutioning is gretly enhnced by dolomitiztion. Dolomitiztion occurs when the clcium in limestone undergoes mole-by-mole replcement with mgnesium from either relict or recent se wter moving through the quifer system. The resulting minerl, dolomite (C, Mg (CO3)), hs crystl structure tht is 3% smller thn clcite (CCO3). Initil losses in quifer mteril due to dolomitiztion my result in quifer compction without significnt increses in porosity. However, once dolomite hs replced pproximtely 7% of the clcite in the limestone, the dolomite crystls re numerous enough to support the quifer strt (Weyl, 96). Further dolomitiztion will result in rpid increses in porosity until the replcement is 8% to 9% complete (Murry, 96). The combintion of frcturing, solutioning nd dolomitiztion hs resulted in the formtion of highly trnsmissive cvity zones in the lower Floridn Aquifer System. In southest Florid, these zones occur exclusively in dolomite dominted strt (Puri nd Winston, 974). These zones pper to be present throughout the study re (CHM Hill, 986, 987; Gerghty nd Miller, 986, 987, 987b) nd re exploited for disposl of secondry treted effluent by ll of the ctive Clss I injection wells. Their highly trnsmissive nd well confined nture combined with their poor qulity mbient wter mke these zones suitble for disposl of secondrily treted wste wter. The origin of wter in the high trnsmissivity, lower producing zones of the Floridn Aquifer System in the study re is not fully understood. Kohout et l. (988) suggest tht the originl se wter present in these lower zones in south Florid hs been mixed with recent se wter which hs migrted lndwrd under hydrothermlly induced grdients. Their studies trce the degree of mixing of relect nd recent se wter in these zones using crbon 4 isotope rtios s mesured in wter smples tken from deep injection wells locted outside the study re. Some of the wter in the lower producing zones of the system comes from mn. In 985, injection wells operting long the southest cost of Florid were injecting pproximtely million gllons per dy of industril nd municipl wste wter into these high trnsmissivity zones (Meyer, 985). The regionl effects of this type of rechrge on ground wter flow ptterns nd hydrotherml grdients in the system hs yet to be determined. Wter Qulity Wter qulity in the Floridn Aquifer System in the study re is poor due to the incomplete flushing of relict sewter by fresh rechrge wter. Flushing occurs primrily in the uppermost producing zones; consequently, wter qulity in the Floridn Aquifer System declines with incresing depth. Chloride concentrtions in the upper producing zones present in Jupiter reverse osmosis well RO- rnged from 85 mg/ t 35 ft below lnd surfce to 9 mg/ t 5 ft below lnd surfce (Gerghty nd Miller, 988). In res such s Jupiter, where there is insufficient Surficil Aquifer System wter vilble to meet demnds, wter from the upper producing zones of the Floridn Aquifer System cn be economiclly treted to potble stndrds using existing reverse osmosis technology.

47 In the deeper, highly-trnsmissive producing zones of the Floridn Aquifer System, where the effects of fresh wter rechrge re negligible, wter qulity is extremely poor; totl dissolved solid (TDS) concentrtions in these wters exceed, mg/. Wter in these zones is of such poor qulity tht the Environmentl Protection Agency (EPA) hs determined this wter does not wrrnt protection from further degrdtion nd injection of industril nd domestic wstes into these zones is llowed throughout the study re.

49 HYDROLOGY GROUND WATER / SURFACE WATER INTERACTIONS Becuse the Surficil Aquifer System is unconfined, surfce wter systems in the study re ffect ground wter levels by rechrging the quifer system when surfce wter levels exceed ground wter levels nd, conversely, drining the quifer system when surfce wter levels re lower thn ground wter levels. The flow rte between the systems is proportionl to the hed differences nd the degree of hydrulic connection between the systems. The degree of hydrulic connection depends on the "wetted" surfce re of the wter body in contct with the quifer, the thickness of bottom sediments in the surfce wter body, nd the hydrulic conductivities of both the quifer nd the sediments. There is little informtion on thickness nd hydrulic conductivity of bottom sediments in the study re (refer to the modeling section for further discussion). However, reltionships between observed surfce nd ground wter levels in the county suggest significnt degree of connection exists between surfce wter systems nd the underlying quifer. Surfce wter systems in or djcent to the study re re so extensive tht they control ground wter levels to lrge degree. These systems (shown on Plte 5) include the Intrcostl Wterwy, Wter Conservtion Are I (WCA-), the West Plm Bech Wter Ctchment Are, the Hillsboro cnl, C-5, C-5, C-6, the L-4 cnl, the L-8 cnl, C-7, C-8, the M cnl, Cler Lke, Lke Mngoni, nd numerous surfce wter mngement systems operted by independent dringe nd wter control districts. Surfce wter systems in the study re my be divided into three groups in terms of their influence on the Surficil Aquifer System: * Mintined systems, chrcterized by wter levels rtificilly mintined t predetermined levels, which rechrge or drin the quifer depending on the hed grdients. * Weir nd structure controlled systems which drin the quifer whenever ground wter levels re bove weir elevtions nd which hve little influence otherwise. * Wter ctchment nd retention systems, tht ctch nd hold excess surfce wter, which provide rechrge to the quifer s long s system wter levels exceed ground wter levels nd which hve little influence otherwise. SURFACE WATER SYSTEMS Surfce Wter System Dt Dt on the surfce wter systems were collected from vriety of sources including system opertors, SFWMD permit files, eril photogrphs, rel estte mps, nd USGS topogrphic qud sheets. Cnl loctions nd system boundries were digitized by SFWMD stff nd incorported into the District's Geogrphic Science dt bse. The informtion herein is s ccurte s possible given the number of sources used nd the limited time for gthering dt.

50 Mintined Surfce Wter Systems Surfce wter systems in or djcent to the study re with mintined wter levels include the Lke Worth Dringe District (LWDD), the Acme Improvement District, the Loxhtchee Groves Wter Control District, the SFWMD C-5 nd Hillsboro cnls, nd WCA- (loctions shown on Plte 5). These systems provide both dringe nd wter supply to the res they serve. All mintined systems re subject to fluctutions depending on the dischrge of excess wter nd the vilbility of outside wter to supplement system wter levels. Subsequent discussions of system opertions re bsed on norml conditions when wter level fluctutions re smll. They do not ddress specil opertions during extreme flood or drought conditions. The Lke Worth Dringe District opertes nd mintins the lrgest nd oldest cnl system in the county. The system serves pproximtely 35 squre miles nd s shown on Plte 5, covers most of the study re south of C-5. Wter levels in the cnls re mintined t specific elevtions rnging from ft. NGVD to tide level vi series of pumps nd control structures. The system is permitted to withdrw billion gllons of wter per yer from WCA-, C-5, C-6 nd the Hillsboro cnl using pumps nd grvity flow to mintin the specified wter levels. Wter is distributed through the system vi four lrge equlizing cnls running north nd south, nd over 5 smller lterl cnls running est nd west. The lrge cnls re generlly 6 to ft. deep nd pproximtely 5 ft. wide while the smller cnls re bout 3 ft. deep nd ft. wide. Loctions of the cnls, pumps, nd control sttions re shown on Plte 6. The system my be subdivided into wter level bsins ccording to cnl wter level mintennce elevtions. The highest wter levels re mintined t ft. NGVD in the centrl bsin with peripherl bsins mintined t progressively lower elevtions s shown on Plte 6. The Acme Improvement District covers pproximtely 7 squre miles west of the LWDD between WCA nd C-5 s shown on Plte 5. Loctions of the Acme cnls, lkes, nd pumping fcilities re shown on Plte 7. From December through June, wter levels in the cnls re mintined t ft. NGVD north of cnl C-3 nd 3.5 ft. NGVD south of it. From July to November, levels re mintined one foot lower throughout the system. Acme is permitted to withdrw wter from C-5 nd WCA- to mintin these levels. Acme's cnls re uniformly constructed with 6 foot bottom widths nd side slopes of : from the bottom to ft. NGVD nd greter thn 4: from ft. NGVD to the surfce. Cnl bottom elevtions rnge from to 6 ft. NGVD. The Loxhtchee Groves Wter Control District serves pproximtely 8 cres djcent to nd north of the C-5 cnl s shown on Plte 5. Mjor cnls in the district re shown on the sme plte. Wter levels in the system re mintined t 6.5 ft. NGVD during the wet seson nd ft. NGVD during the dry seson. The district withdrws wter from C-5 to mintin these levels. The SFWMD Hillsboro nd C-5 cnls re both mintined t control levels. In the study re, C-5 is held t.5 ft. NGVD west of the G-94 nd t 8.5 ft. NGVD from G-94 to the S-55 slinity control structure under norml conditions. The Hillsboro cnl is held t 7.5 ft. NGVD from S-39 to the Deerfield locks. It is tidl est of the Deerfield locks.

51 Weir nd Structure Controlled Surfce Wter Systems Surfce wter mngement systems in the study re whose wter levels re not mintined by pumping include: ) the Indin Trils Wter Control District, ) the Seminole Wter Control District, 3) the South Indin River Wter Control District, 4) the North Plm Bech County Wter Control District (NPBWCD), 5) Prtt nd Whitney, nd 6) the North Plm Bech Heights Wter Control District. The loctions of these systems re shown on Plte 5. Cnl wter levels in these systems re controlled primrily by weirs nd culverts. These systems function primrily s drins nd ffect the quifer only when ground wter levels re bove the cnl levels. Their dringe effects re limited by cnl weir nd culvert elevtions. When cnl levels fll below these elevtions, the systems cese to function s drins. The weir control elevtions for these systems re listed in Tble 4. There re lso severl SFWMD cnls - C-8, C-7, nd L-8 - in the study re where wter levels re not mintined. These cnls re shown on Plte 5. The C-8 cnl is controlled by the C-8 weir just est of S.R. 7 which hs crest elevtion of 7.6 ft. nd by the S-46 gted spillwy which is normlly operted to mintin hedwter stges ner 4.5 ft. NGVD. C-8 is tidl est of Wter levels in the C-7 cnl re controlled by S-44, gted spillwy operted to mintin hedwter stge of 6.6 ft. NGVD during the wet seson nd 7. ft. NGVD during the dry seson. C-7 is tidl est of This informtion ws tken from Cooper nd Lne (988), which lso contins more detiled informtion on the opertion of most SFWMD cnls in the study re. The L-8 cnl functions primrily s wter conduit whose elevtion is dictted by wter vilbility from, nd the wter needs of Lke Okeechobee, WCA-, the L-8 bsin nd the S-5A bsin. Under norml conditions, the SFWMD mintins the southest portion of the L-8 cnl t bout ft. NGVD by pumping wter in from C-5 or by llowing wter to flow in through culvert -A from Lke Okeechobee. Mintining the cnl t this elevtion mkes it possible for the City of West Plm Bech to withdrw wter for rechrge to their wter ctchment system vi pumps locted t the conjunction of the M-cnl nd the L-8 extension. Under drought conditions, the elevtions of the L-8 cnl re mintined only s long s excess wter is vilble from the contributing bsins. Wter Ctchment nd Retention Systems The City of West Plm Bech opertes the lrgest wter ctchment system in the study re. It consists of the M cnl, the Wter Ctchment Are, the crege surrounding the estern leg of the M cnl, nd the crege surrounding nd including Lke Mngoni nd Cler Lke s shown on Plte 5. Wter from this system provides the public wter supply for the City of West Plm Bech. Depending on existing hydrologic conditions, the ctchment system my receive wter from rin, locl surfce wter runoff, or from severl regionl bsins vi the L-8 nd M cnl networks. The regionl bsins which cn supply wter include Lke Okeechobee, WCA-, the L-8 cnl bsin, nd the S-5A bsin. Wter from these res cn be routed through the L-8 cnl to the M cnl intersection. The city is llowed to pump vilble wter from L-8 into the M cnl through which it grvity flows into the wter ctchment re nd the two lkes.

53 On smller scle, there re numerous storm wter retention nd percoltion ponds throughout the study re. These lso hold excess surfce wter nd rechrge the quifer loclly. Wter Conservtion Are (WCA-), which forms the southwest border of the study re, ws constructed by the U. S. Army Corps of Engineers s prt of the originl flood control system in south Florid. Wter level schedules in the re re set by the Corps nd mintined by the SFWMD. Figures 5 nd 6 show the mintennce schedule nd historicl wter levels respectively for the conservtion re. In ddition to direct rinfll, WCA- receives wter primrily from Lke Okeechobee nd the bsins surrounding C-5 nd L-8. GROUND WATER LEVELS Ground Wter Level Dt Regionl ground wter level dt in estern Plm Bech County re limited. The most extensive dt consists of four sets of mesurements tken by the USGS t 74 observtion wells during the periods from /7/83 to /4/83; from 4/6/84 to 4/5/84; from /9/84 to //84; nd from 5/6/85 to 5/8/85. The USGS lso collects dt continuously on recorder equipped wells in the study re. Other wter level dt vilble in the county include mesurements mde by permitted wter users s prt of their slt wter intrusion or wellfield monitoring progrms. While these dt re quite useful in monitoring locl conditions round wellfields, their usefulness in developing regionl mps is extremely limited since dt collection is not coordinted regionlly nd ll mesurements re not referenced to NGVD. Furthermore, wter levels in these wells often reflect chnges in locl pumping rtes or well opertion rottions rther thn regionl trends. Loctions of the USGS wells used in the 983 to 985 smplings re shown on Plte 8. Well informtion nd mesured wter levels re given in Tble 5. Well coverge of estern Plm Bech County is firly good, however, not ll of these wells were mesured for wter levels during ech time period. The ccurcy of the mesured wter levels reltive to NGVD is dependent on the ccurcy of the top of csing elevtion in NGVD. Prior to 988, elevtions of bout hlf of the wter level wells hd been surveyed, while the other hlf hd elevtions estimted bsed on USGS :4 topogrphic qud sheets. In 988, verticl control of 8 previously unsurveyed wells (ll tht could be found) ws estblished. The verge bsolute vlue of the differences between the estimted nd surveyed elevtions ws.45 ft. with ctul differences rnging from.9 ft. to -3.4 ft. Wter levels from the remining unsurveyed wells probbly hve similr rnge of errors. Six previously surveyed wells were resurveyed in 988. Two of these hd pproximtely the sme elevtions in ech survey, but the four others showed differences of -.54,.64,.9 nd 5.46 ft. This smple is bised since severl of these wells were resurveyed becuse the mesured wter levels seemed nomlous. However, wter levels from wells surveyed prior to 988 re used with cution since the potentil for significnt errors in the dt pprently exists. Unfortuntely, the problem ws not identified in time to resurvey the wells for this study. Those wells tht will continue to be prt of the wter level network re being resurveyed.

59 Regionl Levels nd Fluctutions Regionl wter tble mps for April 4-6 nd November 9-4, 984 were developed by Miller (985, 985b) using the vilble ground wter level dt in conjunction with selected surfce wter level dt. The wter tble elevtions shown on these mps re erroneous where they were bsed on dt from wells with inccurte csing elevtions (see discussion in preceding section). However, these mps were used to determine wter level chnges between April nd November since the errors hd equl effects on both mps. To determine the generl flow ptterns nd wter tble elevtion, the November mp ws modified using revised wter levels bsed on the 988 well surveying nd using dditionl surfce wter level dt. The modified mp is presented on Plte 9. Modifiction of one mp ws considered sufficient for these purposes since wter level chnges between April nd November were generlly smll nd did not significntly ffect the regionl flow pttern. Differences between the November nd April wter levels rnged from.5 to -.5 ft. Typiclly, wter levels re expected to be higher during the wet seson thn during the dry seson. However, the period preceding the November (wet seson) 984 wter level mesurements ws dryer thn norml nd the period preceding the April (dry seson) 984 mesurements ws wetter thn norml. As result, the November wter levels were slightly lower (. ft. on verge) thn the April wter levels. The highest wter levels in the study re exceed 4 ft. in lrge mound in the northwest where surfce wter dringe is miniml. Wter levels decrese shrply to the southwest of the mound to the level of the L-8 cnl, which is pproximtely ft. NGVD. Southest of the mound, there is wter level plteu bove 8 ft.

Wter levels to the south of the plteu decline grdully towrds C-5 which forms north/south ground wter divide in the study re with its control elevtion of.5 to 8 ft. NGVD. Wter levels to the est of both the mound nd plteu lso decline grdully reching se level t the cost. Although C-5 nd the ocen determine the net chnge in wter levels south nd est of the mound, wter levels nd grdients in this re re strongly influenced by the numerous surfce wter systems present. In most of the study re south of C-5, wter tble elevtions re controlled by the regulted surfce wter levels of the LWDD cnls. Ground wter levels re highest in the LWDD centrl bsin nd decline outwrd s surfce wter control elevtions decline in the surrounding bsins. Ground wter levels outside the LWDD, in the tringle djcent to C-5 nd WCA- nd west of SR 44, re lrgely controlled by C-5, WCA-, nd the Acme Improvement District cnls. Ground wter levels in this re re lso influenced by the Pine Tree Wter Control District dringe cnls. Chnges in the wter tble elevtion in the study re typiclly follow sesonl rinfll trends with ground wter levels generlly higher during the wet summer months thn during the dryer winter months. The direct correltion between ground wter levels nd rinfll is clerly pprent in Figure 7 which shows historic wter levels in well PB-73 s compred to rinfll t the nerest rinfll sttion, MRF-, in the sme period.

Levels in PB-9 which is only ft. from controlled cnl in the LWDD show only slight response to rinfll s compred to the response in well PB-73 which is pproximtely one qurter mile from the nerest cnl. The loctions of the wells nd rinfll sttions re shown on Plte 8 nd Figure 9, respectively. Ground Wter Flow Ground wter moves from res with high wter levels (hydrulic heds) to res of lower wter levels t rte proportionl to the hydrulic grdient (difference in heds over distnce) nd the hydrulic conductivity of the quifer. Regionl ground wter flow directions re, in generl, perpendiculr to the wter tble contours (equipotentil lines) shown on Plte 9. In the northern prt of the county, the primry flow is rdilly outwrd from the ground wter mound towrd three mjor dischrge res; est to the Intrcostl Wterwy nd Atlntic Ocen; south nd southest to C-5; nd southwest to the L-8 cnl. There ppers to be little flow to the north. In the southern prt of the study re, ground wter generlly flows estwrd from WCA- nd outwrd in ll directions from the LWDD upper cnl bsin system which prllels the Florid Turnpike. Most of the flow from the upper LWDD bsin is directed est to the Intrcostl Wterwy nd north to C-5. Some of the upper bsin flow is lso directed southwest towrd the LWDD bsin bordering WCA-, which lso receives ground wter flow from WCA- due to its low mintennce elevtion. Ground wter flows out of this bsin into the Hillsboro Cnl. Locl ground wter flow my vry from regionl flow ptterns in response to locl hydrulic grdients. This occurs most commonly in the vicinity of production wells which crete locl flow grdients towrd themselves. Locl surfce wter fetures my lso influence ground wter flow. RAINFALL Rinfll rechrges the Surficil Aquifer System over its entire re. Averge nnul rinfll rnges from 56 to 6 inches in the study re (McVicr, 983). Most of this rin, 4 to 46 inches on verge, flls during the wet seson from My through October. Averge rinfll during the dry seson, November through April, is pproximtely 4 to 7 inches. Wet nd dry seson durtions my vry from yer to yer. Rinfll in south Florid is often loclized phenomenon, prticulrly during the wet seson when convective thunderstorms re common. Frequently, these events re very intense nd of short durtion. Conversely, rinfll from frontl systems is more widespred but occurs less frequently. Given the vrible nture of the rinfll ptterns, lrge number of well distributed guging sttions re needed to relibly determine the rinfll frequency nd mgnitude in the study re. Monthly rinfll distribution ptterns in the study re from October 983 to My 985 were mpped bsed-on dt from over 4 rinfll sttions in nd ner the boundries of the study re. Figure 9 shows the sttions used in the study re. The mpping ws done using kriging interpoltion nd contouring progrm (Surfer, Golden Softwre). Kriging interpoltion techniques were used bsed on study by Tbios nd Sls (985) which concluded tht kriging ws one of the best methods for

64 sptil interpoltion of precipittion. Results of the mpping, presented in Appendix D, confirm the lrge sptil vrition in rinfll. Some rinfll does not rech the wter tble to rechrge the quifer but goes insted to interception, surfce wter runoff, evpotrnspirtion, or unsturted soil storge. The percentge of rinfll reching the wter tble to rechrge the quifer is dependent on numerous fctors including the wter tble depth, soil type, vegettion, surficil dringe systems, nd reltive permebility of the surfce. An in-depth investigtion of the percentge of rinfll reching the wter tble ws beyond the scope of this study. However, for development of the ground wter flow models presented in lter sections of this report, the percentge ws ssumed to vry between 5 nd percent depending on the degree of culturl development inferred from county lnd use mps. For further discussion, see the rechrge portion of the ground wter modeling section. EVAPOTRANSPIRATION Evpotrnspirtion (ET), wter loss through evportion nd plnt trnspirtion, is the lrgest source of ground wter loss from the system. ET is complicted process controlled primrily by wether, vegettion, soils, nd wter vilbility. Meteorologic fctors including net solr rdition, ir reltive humidity, temperture, nd wind speed nd durtion re dominnt in controlling potentil ET, the ET rte when not limited by deficiencies in vilble wter (Dunne nd Leopold, 978). Vegettion nd soil fctors, such s vegettion type, soil type, nd soil wter vilbility, become significnt in determining ctul ET, the ET rte when wter supply is limited. The combined effects of ll these fctors mke it difficult to ccurtely estimte ET. There re numerous methods using different combintions of fctors vilble to estimte ET. Two methods, the Penmn Method nd the modified Blney-Criddle Method, were used in this study. The Penmn formul, used in this study to determine potentil ET, is bsed on four mjor climtic fctors, net rdition, ir temperture, wind speed nd sturtion vpor pressure deficit (dryness of the ir). Jones et l., 984, considered this the most relible method for estimting ET from croplnd nd used it to clculte potentil ET for severl loctions in Florid, including Hileh, Florid. Since Hileh nd most of the study re hve similr climtologicl chrcteristics (they re in the sme climtologicl division, lower est cost, s defined by the Ntionl Climtic Center), the Hileh results were used to estimte mximum potentil ET nd the monthly distribution of ET in the study re. Tble 6 shows the Hileh dt nd monthly percentges of nnul ET. The Blney-Criddle formul incorportes crop type, men temperture nd percentge of nnul dylight hours during the month to predict potentil ET. The modified formul, used by the Wter Use Division of the SFWMD, includes coefficients reflecting the growth stge of the crop nd correction for men ir temperture. In contrst to the Penmn method, the Blney-Criddle formul overpredicts ET for the summer months in Florid, by not ccounting for the high percentge of summertime cloud cover (Jones, Allen et l., 984). This method ws used in this study to predict ground wter usge for irrigtion s function of crop consumptive wter use (s described lter in the Clibrtion Period Wter Use section).

67 GROUND WATER MODELING (Surficil Aquifer System) INTRODUCTION The Surficil Aquifer System in estern Plm Bech County ws modeled using the USGS three-dimensionl finite-difference ground wter flow model code, MODFLOW (McDonld nd Hrbugh, 984). MODFLOW is fully three-dimensionl model with modulr code pckges to simulte rivers, rechrge, wells, drins, nd evpotrnspirtion. No-flow boundries re implicit round the edges of the model, nd within the model no-flow or constnt hed boundries my be set. Sources of wter externl to the model cn be represented using the generl hed boundry pckge. There re three itertive solution schemes which my be used in the model, the strongly implicit procedure, the slice-successive overrelxtion technique, nd the preconditioned conjugte grdient method (Kuiper, 987). The vrious MODFLOW pckges with their functions nd use in the Plm Bech models re shown in Tble 7. The study re ws modeled in two prts, north nd south, split t the C-5 cnl s shown in Figure. This llowed finer rel discretiztion thn would hve been prcticl in single model. However, the north nd south discretiztions re comptible so tht the two models my be combined if desired. The north model extends from C-5 north to the Plm Bech - Mrtin County line nd from the Intrcostl Wterwy west to pproximtely the L-8 cnl. The south model extends from C-5 south to the Hillsboro cnl nd from the Intrcostl Wterwy west to Wter Conservtion Are I. GENERAL APPROACH Discretiztion Both models were set up with uniform one hlf mile rel grids, s shown in Figures nd. They shre common cells long the C-5 boundry. Ech model ws verticlly discretized into six lyers so tht vritions in the quifer's hydrulic conductivity nd thickness could be represented. The verticl lyering lso llowed good representtion of both cnl nd well prtil penetrtion effects. The thickness nd verticl extent of lyers in ech model were vried to follow the hydrulic conductivity zones. Detils of the verticl discretiztion for ech model re described in the north nd south county lyering sections lter in this report. Boundry Conditions Both models use combintion of no-flow, constnt hed, nd generl hed boundry conditions. Boundry conditions treted similrly in the two models re discussed below; those specific to ech model re discussed lter in the individul modeling sections. The estern boundry in ech model is the Intrcostl Wterwy where the freshwter/sltwter interfce is ssumed to occur. The interfce is represented in the models by constnt hed cells in the first lyer underlin by no-flow cells in the lower lyers. This is intended to pproximte wedge shped interfce with the freshwter flow forced upwrd by the sltwter wedge to n outflow point bove the sltwter. However, the no-flow cells re not stggered to represent n ctul wedge shpe since the model cells re one hlf mile wide nd the interfce is ssumed to

72 extend over lesser re bsed on vilble costl profiles (Scott, 977). The constnt hed cells were set to.6 ft. NGVD bsed on the verge wter levels observed in the Intrcostl Wterwy in Plm Bech County by Schneider (973). The C-5 nd Hillsboro cnls re ssumed to ct s ground wter divides nd re therefore used s boundries in the models. In the strict sense, these cnls re not true divides since they verticlly penetrte only smll prt of the quifer. However, observed wter levels indicte tht the cnls re cting s divides under present conditions, primrily becuse the cnl wter levels re being mintined below mbient ground wter levels. Significnt stress on the quifer ner the C-5 nd Hillsboro cnls could cuse flow under the cnls; the model's boundries should be djusted ccordingly if such stresses occur or must be simulted. The C-5 nd Hillsboro cnls re represented in the models by generl hed boundries in the first lyer (neither of the cnls penetrtes beneth this lyer). The generl hed boundries ct s constnt hed sources outside the model with conductnce to the model cell they re locted in. Flow between the boundries nd the cells contining them is proportionl to the conductnce which is bsed on the length, width, sediment thickness, nd sediment hydrulic conductivity of the cnl reches represented by the boundries. The direction nd mgnitude of flow is determined by the difference between the heds specified for the boundries nd those simulted for the model cells, thus the boundries represent the cnls cting s either sources to or sinks from the quifer depending on the cnl/quifer hed grdients. The ground wter divide under the cnls is represented by no-flow conditions long the outer edges of the cells contining the cnls nd ll the cells underlying them. The underlying cells were left ctive to llow upwrd flow in the model to represent upwrd lekge into the cnls. Hydrulic Chrcteristics The Surficil Aquifer System is heterogeneous nd nisotropic s result of its widely vried composition. The system is generlly composed of snd or snd/shell lyer overlying limestone/sndstone with selective secondry solutioning. Hydrulic conductivities in the system estimted from pump tests vry over two orders of mgnitude with minimum of 4 nd mximum of 4, ft./dy. The hydrulics of the system re further complicted by the presence of verticlly nd relly discontinuous cly zones. The Surficil Aquifer System ws divided into three hydrulic conductivity zones for modeling purposes; zone of very high permebility representing the Biscyne quifer (zone ); zone of intermedite permebility representing the production zone tpped by most non-biscyne wells in the north county re (zone ); nd zone of low permebility representing the reminder of the system (zone 3). Horizontl hydrulic conductivities of 6, 5, nd 5 ftdy were used for zones, nd 3 respectively. There is little informtion on the verticl hydrulic conductivity of the Surficil Aquifer System in the study re. For the Plm Bech models, verticl to horizontl nisotropy rtio of. ws ssumed for ll zones of the quifer. Only two of the zones, nd 3, were used in the south county model. The production zone, zone, ws neglected since most south county pumpge is from zone, the Biscyne quifer, which extends over the bulk of the modeled re nd is

73 expected to dominte the flow ptterns with its highly trnsmissive nture. All three zones were used in the north county model where the limited extent of the Biscyne mkes permebility differences in the other two zones more significnt. Cly lenses, which re present but not well defined in the quifer, were not represented explicitly in the models since their discontinuous nture gives them locl rther thn regionl influence. Rechrge Rechrge to the quifer from precipittion is simulted by the rechrge pckge in MODFLOW. The pckge, s used in the Plm Bech models, specifies the mount of rechrge pplied to ech ctive cell in the top lyer of ech model. The rechrge my be pplied uniformly or vried relly over the modeled res. Rechrge in the Plm Bech models ws bsed on precipittion nd vried relly using rechrge fctors of (%),.75 (75%), nd.5 (5%) relted to lnd use by the following simplifying ssumptions: ) % of the precipittion reches the wter tble in res composed of predominntly of wetlnds such s the West Plm Bech Wter Ctchment Are nd the Corbett Wildlife Refuge. (Note: there were no such res in the ctive portion of the south county model). ) 75% of the precipittion reches the wter tble in res where the predominnt lnd use types re griculturl, undeveloped, vcnt, golf courses, recretion, very low residentil, low residentil, or medium residentil. 3) 5% of the precipittion reches the wter tble in developed res where the lnd use type is predominntly high residentil or commercil/industril. The resulting distribution of rechrge in the north nd south county models is shown in Figures 3 nd 4. The lnd use mps used to determine the rechrge distribution were developed by the SFWMD Resource Plnning Deprtment (Lshu, written correspondence) nd re shown in Appendix E. Rechrge during the stedy stte phse of model clibrtion ws bsed on n verge rinfll of 6 injyer. Rechrge during the trnsient clibrtion period ws vried monthly nd distributed relly bsed on precipittion dt collected t 3 rinfll sttions in or ner the modeled res (refer to Figure 9). The rechrge estimtes for the predictive runs were bsed on long term rinfll verges (McVicr, 983) of 6 in. per yer, 45 in. per wet seson nd 7 in. per dry seson. Evpotrnspirtion Loss of ground wter to evpotrnspirtion (ET) ws represented in the models with the ET pckge. As the pckge ws used, the modeled ET rte hs mximum when the wter tble is t lnd surfce nd declines linerly with depth to designted extinction depth below which there is no ET. Thus, the ctul rte vries relly throughout the model nd temporlly, from time step to time step, s function of quifer heds reltive to lnd surfce. Mximum ET rtes in the model were bsed on clcultions of free wter evportion by Jones et l. (984) using the

Averge dry seson (November through April) ET ws 3.5 inches. The extinction depth used in the modelling ws set to 7.5 ft. below lnd surfce, the vlue used by Lnd (975) in modeling southest Plm Bech County. Cnls/Lkes Cnls nd lkes were represented in the models using either the drin, river, or generl hed boundry pckges. The generl hed boundry pckge ws used to represent cnls with controlled heds long the model boundries, s previously discussed in the boundry condition section. It ws lso used to represent the West Plm Bech Wter Ctchment Are, the M cnl, Cler Lke, nd Lke Mngoni in the north county model. The river pckge ws used to represent ll other controlled cnls in the models while the drin pckge ws used to represent ll cnls with uncontrolled wter levels. The river pckge functions similrly to the generl hed boundry pckge. It represents ech cnl rech s source of wter outside the quifer with conductnce to the quifer bsed on the cnl length, width or wetted perimeter, sediment thickness, nd sediment hydrulic conductivity within ech model cell. Flow between the cnl nd the quifer is determined by the hed difference existing between the cnl rech nd the model cell contining it nd is proportionl to the conductnce. Heds in the river reches re set to the cnls' control elevtions. Flow direction my be either from the river reches to the quifer or vice vers depending on the direction of the hed grdient. Thus, river nodes my serve s either source or sink of wter with respect to the quifer with both flow volume nd direction vrying ccording to the hed grdients. The drin pckge is similr to the generl hed boundry nd river pckges except tht the drin pckge simultes flow in one direction only, from the quifer to the drin, while the other two pckges simulte flow either into or out of the quifer. The drin conductnces re nlogous to the river nd generl hed boundry conductnces. Flow into the drins occurs when the simulted quifer hed is greter thn the specified drin elevtion. The flow is proportionl to the conductnce nd the difference between the quifer hed nd the drin elevtion. When the elevtion of the drin is greter thn the quifer hed, no flow occurs. Drins were used in the models to represent cnls where wter levels re not mintined t specified heds but re controlled by weirs or structures. The drin elevtions were set to the cnl weir or structure elevtions. SOUTH COUNTY MODEL South Model Verticl Discretiztion The model ws divided into six lyers of vrible thickness. Figures 5 nd 6 illustrte the verticl discretiztion scheme nd resulting model lyering for severl conceptul quifer cross sections. The discretiztion ws designed to chieve lyering such tht:. Lyer contins ll river, drin, rechrge nd evpotrnspirtion cells. Further, it is thick enough so tht the simulted wter tble declines likely to occur in the modeling will not cuse the cells to become excessively thin or dry out.

79 . The upper prt of the quifer, where most of the flow is expected to occur, is represented in the model (lyers to 4) with finer discretiztion thn the lower prt of the quifer (lyers 5 nd 6). Thus, lyers,, 3, nd 4, (where the cnls, rechrge, evpotrnspirtion, nd most of wells re represented) re generlly thinner thn lyers 5 nd 6 (except where the quifer itself thins out in lyer 5 or 6). 3. Any cell in the model represents mteril from only one hydrulic conductivity zone. Lyer extends from the wter tble to - ft. NGVD nd is composed entirely of zone 3. The bottom of lyer nd the tops nd bottoms of lyers 3, 4, 5 nd 6 do not correspond to ny prticulr depths since they were djusted to best represent the quifer's hydrulic conductivity zones nd bottom slope. The discretiztion scheme for these lyers is rther complicted nd follows two step process. First, rbitrry lyer limits were set to meet certin criteri. Then, if necessry, the resulting lyer tops nd/or bottoms were djusted to meet dditionl criteri. The rbitrry lyer limits were set to meet the following criteri:. The bottom of lyer 3 (top of lyer 4) is pproximtely the verge midpoint of the Biscyne zone in its thickest prts so tht the zone could be represented s model lyers (3 nd 4) where it is thickest.. The top of lyer 3 coincides with the pproximte verge top of the Biscynie zone where it is present in lyer The bottom of lyer 4 (top of lyer 5) coincides with the pproximte bottom of the Biscyne zone where it is present in lyer The bottom of lyer 5 (top of lyer 6) is the pproximte verge surficil quifer bottom in the ctive model re. Bsed on these criteri, the initil, rbitrry lyering for the south model is s follows: * Lyer extends from - to -6 ft. NGVD, * Lyer 3 extends from -6 to -9 ft. NGVD, * Lyer 4 extends from -9 to -4 ft. NGVD, * Lyer 5 extends from -4 ft. NGVD to -5 ft. NGVD or the bottom of the quifer if it occurs bove -5 ft. NGVD. * Lyer 6 extends from -5 ft. NGVD to the bottom of the quifer (note tht lyer 6 is inctive in the model where the quifer bottom occurs t depths bove -5 ft. NGVD). This lyering ws used in the model wherever the Surficil Aquifer System ws represented with only one hydrulic conductivity zone. This included res where the Biscyne zone is not present nd res where the Biscyne zone is less thn feet thick. The Biscyne zone ws not represented where it ws less thn feet

80 thick becuse its influence on regionl flow becomes insignificnt s it becomes very thin. In the rest of the model, where both the Biscyne nd non-production hydrulic conductivity zones re represented, the bottom of lyer (top of lyer 3); bottom of lyer 3 (top of lyer 4); nd bottom of lyer 4 (top of lyer 5) were modified s necessry, so tht: ) Only one hydrulic conductivity zone is represented in ech node. ) The Biscyne zone is represented only in lyers 3 nd 4. 3) The Biscyne is represented in lyer 3 or 4 only if it mkes up more thn hlf of the initil unmodified lyer. The computer progrm written nd used for the discretiztion is included in Appendix F to provide the explicit detils of the lyer djustment process. The resulting thicknesses of model lyers through 6 by cell re presented in Appendix G. The consequent distribution of the Biscyne zone (Zone ) in lyers 3 nd 4 is shown in Figures 7 nd 8. South Model Trnsmissivities Trnsmissivities in the model vry directly with chnges in lyer thickness nd hydrulic conductivity zontion. The effective trnsmissivity of lyer lso vries with sturted thickness in response to wter tble fluctutions (the wter tble never dropped below the bottom of lyer ). The MODFLOW code computes the effective trnsmissivity for lyer using its simulted wter tble elevtions nd input dt on cell hydrulic conductivity nd lyer bse elevtion. Trnsmissivities for lyers through 6 were clculted from the lyer thicknesses nd hydrulic conductivity zontion nd input to the model directly. The input dt re given in Appendix H. The composite model trnsmissivity (sum of the trnsmissivities in ll lyers) which pproximtes the totl trnsmissivity of the Surficil Aquifer system is shown contoured in Figure 9. Lyer trnsmissivities for the composite clcultion were estimted bsed on the verge wter tble level. South Model Boundries The south model's ctive re extends southwrd from C-5 to the Hillsboro Cnl nd westwrd from the Intrcostl Wterwy to Wter Conservtion Are. Boundry conditions for ech model lyer re shown in Figures to 3. The Hillsboro Cnl nd C-5 re treted s ground wter divides using generl hed boundries s discussed in the ground wter modeling introduction. The cnl widths used to clculte the boundry conductnces were estimted from eril photos. C-5 widths rnged from 9 to ft. nd the Hillsboro Cnl widths rnged from 8 to ft. Cnl sediment verticl hydrulic conductivities for the clcultions were estimted s.5 ft./dy for both cnls bsed on the model clibrtions (further discussion in Model Clibrtion section). The cnl widths nd clculted cnl conductnces re given in Appendix I, tble I-, which summrizes the generl hed boundry input dt.

88 Wter Conservtion Are ws treted s constnt hed boundry in ll lyers. Its hed ws set t 5.4 ft., the verge vlue during the clibrtion period, November 983 to My 985. Historiclly, wter levels in the conservtion re hve fluctuted severl feet, however, becuse the fluctutions re not predictble, the 5.4 ft. ssumption ws lso used for the predictive runs. Impcts of neglecting fluctutions during the clibrtion period re discussed in the clibrtion section. The Intrcostl Wterwy nd sltwter/freshwter interfce were treted s combintion constnt hed/no-flow boundry s discussed previously in the boundry condition section. South Model Cnls Cnls in the southern study re include the LWDD cnls, the Acme Improvement District cnls, nd miscellneous cnls. These cnls were represented with the river nd drin pckges in the model. All cnl sediments were ssumed to be one foot thick with hydrulic conductivity of.5 ft.idy (determined by model clibrtion). The LWDD nd Acme Improvement District cnls hve controlled wter levels nd were represented in the model using the river pckge. Becuse these cnl systems re so extensive, most cells in the first model lyer contined cnl reches represented s rivers s shown in Figure 4. Control elevtions in the Lke Worth Dringe District rnged from se level to ft. NGVD. The cnl rech conductnces for the LWDD cnls were computed ssuming widths for ft. for the lterl cnls nd 5 ft. for the equlizing cnls. Control elevtions in the Acme Improvement District were set to ft. north of the C-3 cnl nd 3.5 ft. south of it. Conductnces for Acme cnls were computed using widths of ft. Appendix I, tbles I- nd I-3 summrize the river node input dt. Most of the remining cnls in the southern study re re prt of the Pine Tree Dringe District which is locted west of the Acme Improvement District, between C-5 nd the Wter Conservtion Are. There is little specific informtion vilble on those cnls. They were ssumed to be uncontrolled nd were modeled s drins with cutoff elevtions equl to the Acme Improvement cnl control elevtions. Cnl densities nd n verge cnl width ft. were estimted from Mrk Hurd eril photogrphs. Appendix I, tble I-4 summrizes the resulting drin input dt for these cnls. NORTH COUNTY MODEL North Model Verticl Discretiztion The model ws divided into six lyers of vrible thickness. The tops nd bottoms of the model lyers do not correspond to ny prticulr quifer depths since the lyers were djusted to best mtch the quifer's hydrulic zones nd bottom. Figures 5 to 7 illustrte the verticl discretiztion scheme nd resulting model lyering for three conceptul quifer cross sections. The discretiztion ws designed to chieve lyering similr to tht in the south county model, except in the north model, cells my represent mixture of mterils from different hydrulic conductivity zones. The discretiztion scheme ws gin complicted two step process of setting rbitrry lyer limits nd then djusting them to best mtch the hydrulic conductivity zones. The rbitrry lyer limits were set identicl to those

However, the following lyer djustments were much more complicted in the north model thn in the south since n dditionl conductivity zone (the production zone) hd to be included. Adjustments in the north county model were mde to the bottom of lyer (top of lyer ); bottom of lyer (top of lyer 3); bottom of lyer 3 (top of lyer 4); nd bottom of lyer 4 (top of lyer 5) to meet the following hydrulic conductivity zone distribution criteri: ) Lyer contins only zone 3. ) Cells in lyers 3 nd 4 re composed only of zone where t lest ft. of zone ws contined in the undjusted lyers. 3) Lyers 5 nd 6 do not contin zone except where lyer 4 is composed of zone. 4) Zone, the Biscyne zone, ws represented only where it ws greter thn ft. thick. The computer progrm written nd used for the discretiztion is included in Appendix J to provide the explicit detils of the lyer djustment process. The resulting thicknesses of ech model lyer by cell re given in Appendix K. The distribution of hydrulic conductivity zones in ech lyer re shown in Figures 8, 9,, nd 3.

103 The C-5 cnl is treted s ground wter divide s previously discussed. The L-8 cnl, which forms most of the western boundry of the model's ctive re ws treted s constnt hed boundry with n elevtion of ft. NGVD for the clibrtion period (its verge vlue during tht period) nd during predictive simultions. A constnt hed boundry ws lso used in the northwest corner of the model where wter level mps show ground wter mound generlly exists. Wter levels long the boundry were vried from ft. to 4 ft. ccording to the wter level mp on Plte 9. There is little wter level dt vilble long the northern border of the modeled re. Most wter tble mps (Plte 9; Miller, 985, 985b) show equipotentil contours lmost perpendiculr to the county line implying no flow or limited flow condition. The northern boundry of the model ws therefore set to no flow boundry. North Model Cnls Cnls were represented in the model with the river pckge where cnl wter levels re mintined nd with the drin pckge where levels re not mintined. The distribution of cells contining rivers nd drins in model lyer is shown in Figure 37. The cnls do not penetrte model lyers, 3, 4, 5 or 6. Sediment in ll cnls ws ssumed to be foot thick with hydrulic conductivity of.5 ft./dy (determined by model clibrtion) for clcultion of the river nd drin conductnces. Only one of the numerous cnl systems in the north model re, the Loxhtchee Groves Wter Control District (Plte 5), hs mintined levels (refer to Tble 4). Appendix N, tble N- summrizes the widths, control elevtions, nd river pckge input dt for these cnls. The remining cnl systems re not mintined (refer to Tble 4) nd were represented with the drin pckge. Appendix N, tble N- summrizes the widths, weir elevtions nd drin pckge input for these cnls. CALIBRATION Introduction Idelly, the Plm Bech county models would hve been clibrted to stedy stte conditions using predevelopment dt nd to trnsient conditions using dt from n extended period with chnging conditions. Unfortuntely, regionl wter level dt in Plm Bech County re sprse. There re little or no dt for predevelopment conditions nd vilble county wide mesurements re limited to four sets of dt collected by the USGS between October 983 nd My 985 t 74 observtion wells (loctions shown on Plte 8). These dt sets, presented in Tble 5, were used to clibrte the Plm Bech County models. The models were clibrted with dul pproch. First, stedy stte clibrtion ws mde ginst the verge wter levels mesured from /83 to 5/85 (the clibrtion period) using verge rechrge nd dischrge vlues for the period in the model. Next, trnsient clibrtion ws mde ginst chnges in mesured wter levels during the sme period using monthly time steps in the models with rechrge nd dischrge vried ccordingly. The wter level dt were not idelly suited to either the stedy-stte or trnsient clibrtion. Wter levels were not ctully t stedy stte during ny of

105 the mesurement periods for true stedy stte clibrtion, however, chnges in mesured levels were generlly smll nd the totl mesurement period is quite short for trnsient clibrtion. Some of the dt re further limited becuse the observtion well elevtions were never surveyed or becuse the relibility of the surveying is questionble (see previous discussion in Hydrology Section). The sensitivity of the mesured wter levels to rinfll nd chnges in surfce wter levels further complictes the clibrtion. The wter tble responds lmost immeditely to rinfll s previously discussed. Thus, locl rinstorm during ny of the mesuring periods could result in wter level increses in selected wells reflecting locl phenomen rther thn regionl trend. Temporry chnges in cnl levels would hve similr effect on locl wter levels. Clibrtion Period Wter Use Individul wter use permits were used s the bsis for estimting the mgnitude nd loction of ground wter pumpge during the clibrtion period. Well loctions nd depths re given in the permit stff reports. Monthly public wter supply pumpge for the clibrtion period ws obtined directly from reports submitted to the District s prt of the permit limiting conditions. Pumpge by other users ws estimted bsed on crop wter requirements determined by modified Blney-Criddle method less the effective monthly rinfll (explined below). Wter use by generl permit holders ws not modeled becuse the quntities were not significnt compred to individul permit use. Reported public wter supply pumpge in the study re during the 8 month clibrtion period ws billions gllons (n verge of 8.4 mgd). Sixty-eight percent of this ws from the south study re with the reminder from the north study re. Averge monthly pumpges for the period by utility nd wellfield re given in Tble 8. Wellfield loctions re shown on Plte. Model node loctions nd pumpge by month for ech utility re given in Appendix O. Almost ll non-public wter supply consumptive ground wter use in the study re ws for irrigtion. Irrigtion wter use my be divided into two ctegories. Agriculturl wter use, primrily for smll vegetbles nd nursery plnts, nd nongriculturl wter use, primrily for golf course nd lndscping irrigtion. All of the griculturl crege, 3,78 cres, irrigted during the clibrtion period ws in the southern modeled re. The totl non-griculturl crege irrigted in the sme period ws 6,44 cres with 4,69 cres (73% of the totl) in the southern study re nd the reminder in the northern re. Non-griculturl nd griculturl wter use estimtes were mde bsed on the modified Blney-Criddle formul for determining evpotrnspirtion used by the SFWMD in the wter use permitting process. The Blney-Criddle formul ws used to mintin consistency between permitted nd modeled wter use. The modified Blney-Criddle formul (s described in SFWMD Permit Informtion Mnul, Volume 3) ws used to determine monthly evpotrnspirtion of the irrigted vegettion on permit by permit bsis. Mesured rinfll ws then subtrcted from the clculted ET to determine the supplementl wter requirement for ech permittee for ech month in the clibrtion period. The supplementl wter requirement corrected for irrigtion efficiency is the estimted wter use. Irrigtion efficiencies of 75 nd 5 percent were used for spry nd flood irrigtion, respectively. Some permits were for combined ground nd surfce wter use with no specified

The loctions of permitted griculturl nd non-griculturl wells used in the model clibrtion re shown on Plte. Permit informtion, well loctions in the models, nd monthly wter use estimtes for the clibrtion period re given in Appendix O. Stedy Stte Clibrtion Approch The stedy stte clibrtions were bsed on the ssumption tht ground wter levels during the clibrtion period were fluctuting round stedy stte condition s result of sesonl vritions in rinfll, pumpge, evpotrnspirtion nd cnl levels. Further, the verge mesured ground wter levels during the period were ssumed to pproximte stedy stte levels under verge nnul conditions. Thus, the stedy stte clibrtions were mde bsed on comprison of simulted wter levels under typicl nnul rechrge/dischrge conditions versus the verge mesured wter levels in surveyed wells during the clibrtion period. Dt from ll surveyed wells were used in the clibrtions to provide sufficient distribution of clibrtion points. The model clibrtions re not unique since there re numerous input prmeters which cn be djusted in vrious combintions to give equivlent mtches between the simulted nd sprse mesured heds. Input prmeters initilly vried in the clibrtion runs included rechrge, evpotrnspirtion, cnl conductnces, quifer hydrulic conductivities, nd the horizontl to verticl hydrulic conductivity nisotropy rtio. The quifer hydrulic conductivities nd nisotropy were returned to their originl vlues fter severl clibrtion runs when the model proved much more sensitive to the other fctors. Thus, rechrge, evpotrnspirtion, nd cnl conductnces were the only prmeters chnged s result of the clibrtions. Fctors not vried in the clibrtion runs were well dischrges nd boundry conditions. Boundry conditions were set s previously described nd well dischrges were set t verges for the clibrtion period computed s described in the wter use section. The rechrge nd evpotrnspirtion rtes in the models were initilly combined into one net rechrge term to simplify the modeling. However, this pproch proved unsuccessful in the northwest portion of the north model where the modeled heds mounded to levels well bove lnd surfce. Wter mounded in tht prticulr re of the model becuse there re no cnls for surfce wter dringe of excess wter nd the low trnsmissivities of the quifer prevents rpid dringe through ground wter underflow. In ctulity, tht re is mrshy nd does flood during the wet seson; however, the model does not hndle flow or ponding bove lnd surfce well, which results in simultion of n extreme unrelistic mound. Further exmintion of rinfll nd precipittion rtes showed tht potentil nnul free wter surfce evportion exceeds verge nnul rinfll. When evpotrnspirtion nd rinfll were seprted nd set ccordingly in the models, the problem ws resolved. The north nd south models were clibrted concurrently to mintin consistency between models. The clibrted cnl sediment conductivities, the hydrulic conductivities of quifer zones,, nd 3, the mximum rechrge, nd the evpotrnspirtion prmeters were the sme for both models. Clibrted stedy stte model prmeters re shown in Tble 9. Unique spects of ech model

109 clibrtion nd comprisons of the mesured nd simulted wter levels for ech model re described in seprte north nd south clibrtion sections. Trnsient Approch The trnsient clibrtion runs were mde to determine the best specific yield vlue for the models bsed on comprison of simulted chnges in ground wter levels versus mesured chnges during the clibrtion period. The trnsient clibrtion runs simulted conditions from October 983 to My 985 using 5 dy time steps. Well pumpges, rinfll, nd evpotrnspirtion were vried monthly. Cnl levels were not vried. The simulted heds from the clibrted stedy stte runs for verge nnul conditions were used s initil heds in the trnsient runs. Since these heds re not representtive of the trnsient conditions existing in the quifer system in October 983, model results from the first six months of the simultions were not used for clibrtion. Sensitivity runs with the strting heds incresed nd decresed twenty-five percent showed tht the strting heds hd little influence on the modeled results fter this period. The trnsient clibrtions were hindered by the smll chnges in mesured ground wter levels. Mesured levels in the north nd south county modeled res chnged n verge of only.48 ft nd.56 ft respectively from April to October 984 nd.75 ft nd.5 ft respectively from October 984 to My 985. Unfortuntely, hed chnges of these mgnitudes cn be ttributble to severl fctors not fully represented in the models. The most importnt of these in the Plm Bech models re surfce wter levels nd loclized rinfll. As previously discussed, quifer heds re extremely sensitive to cnl levels. Although mintined cnl levels re reltively stble in the long term, there is some vribility in levels on monthly bsis. Cnl levels were not vried monthly in the model during the clibrtion period both becuse of dt deficiencies nd becuse of the complexity of generting the model dt sets. Therefore, chnges in ground wter levels resulting from chnges in cnl levels re not represented in the models. Precipittion rechrge ws vried monthly nd relly ccording to mesured rinfll during the clibrtion period. However, locl rinfll is not necessrily well represented in the model in res without rinfll sttions. Further, the rechrge is pplied in the models evenly over the monthly stress periods, while ctul quifer rechrge is occurring spordiclly over the month. Due to the limittions discussed, which resulted in mrginl greement between simulted nd mesured wter level chnges (discussed in the Clibrtion Results below), the trnsient runs were used only to estimte specific yield nd to double check the model clibrtion. The models were run with specific yields vrying from.3 to. nd the specific storge coefficient for the lower lyers fixed t x -6. A specific yield of.5 ws selected bsed on the trnsient clibrtion results which re described in the following north nd south model clibrtion sections. North County Model Clibrtion Results Clibrted stedy stte heds in model lyer representing verge nnul conditions in the quifer during the clibrtion period re shown in Figure 38. Simulted heds in other lyers re not shown since differences between lyers re slight.

111 shown in Figure 39. Differences between the verge mesured levels nd minimum nd mximum mesured levels re shown in the sme figure. The simulted stedy stte wter levels mtch the verge mesured wter levels firly well. The shpe of the simulted wter tble (Figure 38) ppers resonble with no pprent rel trend in differences from the verge mesured wter levels. Almost hlf of the simulted observtion well wter levels were within the rnge of mesured wter levels (Figure 39). The remining simulted well levels were within bout one foot of the mesured rnge in most cses with exceptions t wells PB-687, PB-9-A, PB-75, PB-845 nd PB-789. The worst mtch between simulted nd mesured observtion well wter levels occurred t well PB-687. Its elevtion ws resurveyed so the well hed elevtion should be ccurte. This well is locted t the edge of the South Indin River Wter Control District which ws represented in the model using drin nodes with control elevtions from.5 to 3 feet. The stedy stte simulted levels in this re reflect these control elevtions. PB-687 is one qurter mile from the nerest dringe cnl, but it is locted in drin cell in the model. This discretiztion results in simulted levels lower thn ctul levels, lthough difference of over four feet is extreme. Apprently either the re is not well drined (mesured wter levels re only -3 feet below lnd surfce) s result of low hydrulic conductivity zones not represented in the model or there re errors in the reported mesurements. PB-9 nd PB-75 re prt of nested well cluster t the western end of C-8. Simulted levels for both, which re significntly lower thn mesured levels, re lrgely controlled by the drin cells representing C-8. The mesured levels seem nomlously high given the wells' close proximity to C-8 where the surfce wter levels re generlly 3 to 4 ft. lower thn the mesured well levels. C-8 does drin the quifer in tht re, nd it is possible tht there is high ground wter to surfce wter hed grdient in the re resulting from some locl, low permebility quifer mteril not represented in the model. Such grdient ws not mesured within the nested well depths, so the low permebility zone would be expected to occur t less thn 35 ft (the depth of the shllowest well) if it is present. These wells were not resurveyed during this study, so it is lso possible tht the well elevtions re erroneous. Trnsient clibrtion runs were mde for specific yields of.,. nd.3. Agreement between simulted nd mesured wter level chnges (s determined by the sum of squres of the residuls) ws significntly better for the. nd.3 specific yield runs thn for the. runs. However, the sum of squres of the residuls were not significntly different for the. nd.3 runs. Therefore, specific yield of.5 ws chosen for the reminder of the modeling. The differences between simulted nd mesured wter level chnges from the end of April 984 to the beginning of November 984 nd from the beginning of November 984 to the beginning of My 985 for the selected specific yield of.5 re shown in Figures 4 nd 4. Agreement between simulted nd mesured chnges is mrginl becuse the model is not well suited to simulte the smll chnges tht occurred during these periods s previously discussed.

Differences between simulted stedy stte wter levels nd verge mesured wter levels t ech observtion well re shown in Figure 43. Differences between the verge mesured levels nd minimum nd mximum mesured levels re shown in the sme figure. The simulted stedy stte wter levels mtch the verge mesured wter levels well. The shpe of the simulted wter tble (Figure 4) is consistent with the verge mesured levels with no pprent rel trend in discrepncies between the two. Simulted wter levels re within the rnge of mesured wter levels for hlf of the observtion wells (Figure 43) nd re within hlf foot of the mesured rnge for most of the remining wells with the exception of PB-55 which is within foot nd PB-445 which is off by bout two feet. It is possible tht the mesured wter level in PB-445 is erroneous since its elevtion ws not resurveyed. The differences between simulted nd mesured wter level chnges in observtion wells from the end of April 984 to the beginning of November 984 nd from the beginning of November 984 to the beginning of My 985 for specific yield of.5 re shown in Figures 44 nd 45. Agreement between the simulted nd observed chnges is mrginl s it ws in the north county model. However, in the south county model, chnges in specific yield hd little effect on the simulted chnges nd did not significntly ffect the mtch between simulted nd mesured levels s determined by the sum of squre of the residuls. A specific yield of.5 ws used in the reminder of the modeling to mintin consistency with the north model. SENSITIVITY ANALYSIS Approch Sensitivity nlyses were conducted on both models by vrying the quifer hydrulic conductivities, nisotropy rtio, cnl sediment hydrulic conductivity, evpotrnspirtion prmeters, nd rechrge fctors. The effects of the prmeter chnges under stedy stte conditions were determined by compring simulted heds nd mss blnces from the sensitivity runs to those from n unchnged bse run. The bse run prmeters were s follows: ) For the north nd south model rechrge fctor runs - bse run prmeters were equl to their finl clibrted vlues. ) For ll other south model runs - bse run prmeters were equl to their finl clibrted vlues except for cnl sediment hydrulic conductivity which ws double ( ft/dy) its finl clibrtion vlue. 3) For ll other north model runs - bse run prmeters were equl to their finl clibrted vlues except for cnl sediment hydrulic conductivity nd non- Biscyne production zone hydrulic conductivity, which were both double ( ft/dy nd ft/dy respectively) their finl clibrtion vlues. 4) For ll north model runs - the bse runs were mde with North Plm Bech County Wter Control District Units nd 4 misrepresented s rivers. These units re represented s drins ( more pproprite representtion for regionl flow) in the clibrtion nd predictive runs.

120 Differences between bse run prmeters nd the finl clibrted prmeters re due to clibrtion djustments mde fter the sensitivity runs were complete. Results The north county model sensitivity runs nd their results re summrized in Tble. The resulting hed chnges re'shown in Figures P- to P- in Appendix P. Mss blnce summries re shown in Figures 46 to 5. The south county model sensitivity runs nd their results re summrized in Tble. The wter level chnges resulting from the vrious prmeter chnges re shown in Appendix P, Figures P- to P-4. Mss blnce summries for the sensitivity runs re shown in Figures 5 to 57. The sensitivity of simulted wter levels to prmeter chnges vried throughout the models primrily s function of surfce wter systems nd wellfield influences. Prmeter chnges hd different effects in model res with cnls thn in res without them nd, further, hd different effects in res where cnls wter levels re mintined thn in res where they re not. Wter Levels Modeled ground wter levels in the study re were lest sensitive to prmeter chnges in the vicinity of the West Plm Bech Wter Ctchment Are where no significnt wter level chnges were observed during the sensitivity runs. This is the result of the strong influence of the ctchment re on ground wter levels in the underlying quifer combined with the lck of stress on the quifer under the re. Simulted ground wter levels in res with cnl systems with mintined wter levels were firly insensitive to most prmeter chnges. Chnges in cnl sediment hydrulic conductivity hd the gretest influence in these res. Decresed sediment conductivity which retrded the quifer-cnl connection resulted in decresed ground wter levels where the cnls re rechrging the quifer nd incresed ground wter levels where they re drining it. Both effects re evident in the southestern study re where levels drop in the south end of the LWDD's ft bsin but rise in the djcent 4.5 ft. bsin. Incresing the cnl sediment hydrulic conductivity hd the opposite effect. Ground wter levels in res where cnl levels re not mintined were lso primrily sensitive to chnges in cnl sediment hydrulic conductivities. Decresed hydrulic conductivity cused ground wter level increses s the cnls becme less effective drins. Similrly, hydrulic conductivity increses cused ground wter level decreses but to lesser extent. Ground wter levels in model res with no cnls were influenced minly by chnges in the evpotrnspirtion prmeters. This ws prticulrly evident in the northwest corner of the model where the ground wter mound incresed up to feet when mximum evpotrnspirtion ws reduced 5%, nd precipittion in the re exceeded evpotrnspirtion. These increses re unrelistic since such wter levels re bove lnd surfce. However, they demonstrte both the importnce of evpotrnspirtion in mintining relistic wter levels in tht re nd the limittions of modeling only the ground wter component in res which flood nd experience overlnd flow. In such res, coupled-ground wter/surfce wter flow model would provide -better representtion of the physicl system. Wter levels in undrined res were lso sensitive to the evpotrnspirtion extinction depth; when

137 the depth ws decresed, wter levels incresed. Agin, this demonstrtes the importnce of evpotrnspirtion in undrined res. Ground wter levels in the vicinity of-wellfields Were sensitive to chnges in quifer horizontl nd verticl conductivity, nd tr-chnges in the verticl- to horizontl nisotropy rtio. Ground wter levels in the northest corner of the model were extremely sensitive to chnges in quifer hydrulic conductivities, the horizontl to verticl nisotropy rtio, nd cnl sediment conductivities. This is due primrily to the effects of the Jupiter Wellfield in combintion with the no flow nd constnt hed boundries in the re, the C-8 cnl nd the North Plm Bech Wter Control District Unit 3. Mss Blnce The influence of prmeter chnges on the vrious components of model inflow nd outflow my be observed by compring mss blnces from the sensitivity runs. Chnges in cnl sediment hydrulic conductivity nd in ET prmeters cused the lrgest chnges in the flow components. Inflow nd outflow from drin nodes, river nodes nd generl hed boundry nodes were influenced directly by chnges in cnl sediment hydrulic conductivity. Increses in sediment conductivity incresed conductnce from these nodes to the quifer thereby incresing both inflow nd outflow through the nodes. Decreses in cnl sediment hydrulic conductivity hd the opposite effect. The chnges re nonliner. ET ws ffected indirectly by chnges in cnl sediment hydrulic conductivity s result of ground wter level chnges. Where ground wter levels were incresed by the chnges, ET rtes incresed (recll tht the ET rte is function of depth to wter); similrly where ground wter levels decresed, ET rtes decresed. The net effect, in the north model, ws n increse in ET rtes with decresed cnl sediment hydrulic conductivity nd vice vers. Chnges in ET prmeters ffected ET outflow directly nd drin outflow indirectly. Obviously, decresing either the mximum ET rte or the ET extinction decresed the ET outflow. However, the sme chnges lso incresed drin outflow indirectly by incresing ground wter levels. The opposite would be expected if the ET prmeters were incresed. 5.

139 PREDICTIVE SIMULATIONS INTRODUCTION Predictive simultions of vriety of meteorologic nd mngement scenrios were run with the clibrted north nd south county models. The scenrios were designed to: ) evlute Surficil Aquifer System conditions nd identify potentil problem res under the different scenrios, nd b) determine the impcts of severl fctors including wter use, surfce wter system mngement, dry seson conditions nd drought conditions on the quifer system. Identifiction of problem res focused primrily on the potentil for sltwter intrusion long the cost. Intrusion potentil from estwrd migrtion of connte brckish wter in the western portion of the study re is not ddressed since the loction nd extent of the connte wter is not well defined regionlly. The models re not well suited for determining the ctul occurrence of sltwter intrusion. Approximting the fresh wter zone t the sltwter/freshwter interfce in the models s being bounded by verticl no flow line topped by constnt hed node ws felt to be sufficient for simulting regionl flow. However, the pproximtion is crude when compred to models tht ctully clculte the position of the sltwter/freshwter wedge. Without using vrible density solute trnsport model or shrp interfce model, sltwter intrusion cnnot be considered quntittively. However, flow direction, flow mgnitude, nd costl wter levels simulted by the flow models cn be used s indictors of where potentil for intrusion exists. Further, these indictors cn be used to compre the reltive potentil for intrusion under different conditions. Simulted flow direction, flow mgnitude, nd wter levels in the model nodes djcent to the constnt hed nodes representing the Intrcostl Wterwy were used s sltwter intrusion indictors s follows: ) Potentil for intrusion ws considered high where simulted flow is from the constnt hed nodes into the modeled re. As the models re set up, this implies sltwter flow into the system. This potentil is ssumed to increse directly with the mgnitude of westwrd flow. b) Potentil for intrusion ws considered moderte where simulted wter levels in the nodes djcent to the constnt hed nodes re less thn 4 ft. NGVD. Selection of the 4 ft. criteri is empiricl, bsed on dt from sltwter intrusion monitoring progrms t Lntn nd Lke Worth which show sltwter intrusion occurrnng with costl heds of 4 ft. or less. This potentil is ssumed to increse with declines in simulted costl heds. c) Potentil for intrusion ws considered low where simulted heds djcent to the constnt hed nodes were greter thn 4 ft. NGVD. The potentil is ssumed to decrese with increses in simulted costl heds. Selection of the 4 ft. NGVD criteri is not intended to imply tht intrusion will necessrily occur when costl heds re less thn 4 ft. or tht it will not occur when they re greter. There re numerous other fctors which combine with the costl heds in determining the occurrence nd extent of sltwter intrusion.

140 The models were lso used to identify res where wter tble drwdowns resulting from withdrwls re likely to hve dverse environmentl impcts on wetlnds. Numerous wetlnds exist in the study re, prticulrly in the northwest. A regionlized mp of wetlnds in the study re developed from informtion provided by the District's Resource Control Deprtment is shown in Figure 58. Ground wter withdrwls were considered likely to cuse dverse environmentl impcts on these wetlnds where simulted wter level drwdowns resulting from the withdrwls extend under the mpped wetlnd res. The-likelihood nd probble extent of dverse impcts is ssumed to increse proportionlly with the mount of drwdown. Two levels of ground wter use, llocted nd buildout, were considered in the simultions. Allocted wter use simultions represent ll present ground wter users with individul wter use permits pumping t their totl lloctions. Buildout wter use simultions represent projected future public wter supply use for one possible buildout development scheme. The llocted wter use runs re intended to provide insight into quifer conditions nd potentil problems likely to exist presently or in the ner future. The buildout wter use runs re intended to provide insight into the sme issues in the long term. Both llocted nd buildout wter use runs were mde for the following scenrios: verge nnul conditions; simulted by stedy stte model runs with verge nnul rechrge, verge nnul evpotrnspirtion, nd existing surfce wter system mngement. verge dry seson conditions; simulted by six month trnsient model runs with verge dry seson rechrge, verge dry seson evpotrnspirtion, nd existing surfce wter mngement. 9 nd 8 dy droughts; simulted by 9 nd 8 dy trnsient model runs with no rinfll rechrge, verge evpotrnspirtion, nd existing surfce wter system mngement. Additionl simultions were mde to determine the impcts of wter use nd the impcts of mintined surfce wter systems. Allocted wter use impcts were determined by compring the results of simultions with no wter use to simultions with llocted wter use. Impcts from incresing wter use to buildout levels were determined by compring simultions with buildout wter use to those with llocted wter use. The impcts of mintined surfce wter systems re determined in similr mnner by compring the results of llocted wter use simultions with mintined surfce wter systems (represented using the river pckge) to simultions with the sme systems unmintined (represented using the drin pckge). ALLOCATED WATER USE It is useful in permitting dditionl wter use to know the theoreticl stress on the quifer from lredy permitted use. Wter use permits in Plm Bech County re typiclly vlid for period of up to ten yers from the dte of issunce. The llocted quntity when the-permit is issued is intended to meet the permittee's mximum need during the. period. Since permit-expirtion dtes re stggered, ctul wter use t ny given time is not necessrily representtive of llocted wter use. 9

142 The llocted wter use for the simultions represents most individul wter use permit lloctions s of Februry 989 for public wter supply use nd July 988 for other uses. Industril nd dewtering ground wter uses, which typiclly hve onsite retention or djcent reinjection of wter, were not considered in the llocted wter use. Generl permit wter use ws not included in the models becuse records suggest tht totl generl permit lloctions re smll compred to individul permit lloctions. For discussion purposes herein, llocted ground wter use hs been subdivided into three use types: public wter supply, griculturl, nd non-griculturl. The first two re self-explntory; the third, non-griculturl use, includes ll other uses, but consists predominntly of golf course nd lndscpe irrigtion. Public wter supply comprises the lrgest clss of consumptive ground wter use in estern Plm Bech County, with permitted lloctions from the Surficil Aquifer System totling 68. billion gllons per yer s of Februry 989. Thirty permitted users presently operte 53 wellfields in the study re. Current lloctions for these public wter supplies re given in Tble. Other permit informtion nd model cell loctions for ech utility re given in Appendix Q, Tbles Q- nd Q-. Totl public wter supply lloctions for ground wter from the south study re (45.68 billion gllons per yer) re bout twice those from the north re (.53 billion gllons per yer). The difference between the north nd south ground wter lloctions is due to severl fctors; greter popultion density nd higher per cpit demnd in the south, nd use of surfce wter rther thn ground wter by the City of West Plm Bech in the north. There re 45 individul permits for griculturl ground wter use in the study re, mostly for smll vegetble nd nursery plnt irrigtion, s described in Appendix Q. About hlf of these permits re for ground wter use lone, the other hlf re for combintion of ground wter nd surfce wter use. The totl wter use lloction for these permits is 8.85 billion gllons per yer, ninety-nine percent of which is permitted in the south county re. Since most permits for combined ground wter/surfce wter use do not specify n lloction brekdown between the two, percentge of the lloction, equl to the ground wter percent of totl permitted surfce nd ground wter withdrwl cpcities, ws rbitrrily used in the ground wter modeling. Individul non-griculturl wter use permits for ground wter in the study re re summrized in Appendix Q. Sixty-three percent of these permits re for ground wter use lone, the rest re for combined ground wter/surfce wter use. The totl non-griculturl lloction in the study in 988 ws 9.6 billion gllons per yer; 3.39 bgy in the south nd 5. bgy in the north. AVERAGE ANNUAL CONDITIONS (Allocted Wter Use) Averge nnul conditions in the Surficil quifer were pproximted by stedy stte model simultions using estimtes of verge nnul rechrge nd evpotrnspirtion (refer to previous discussions in Ground Wter Modeling, Introduction, Rechrge nd Evpotrnspirtion). Simulted wter levels in lyer under these conditions re shown in Figures 59 nd 6. Levels in other lyers were similr nd re therefore notshown. The mss blnces with the modeled inflow nd outflow components regiven in Tble 3. The simulted ground wter levels re generlly similr to the wter levels generted in the stedy stte clibrtion runs.

147 southern study re reflect the mintined surfce wter system elevtions, s do those in the vicinity of the West Plm Bech Wter Ctchment System in the northern study re. Drwdowns re pprent round mny. mjor wellfields including Jupiter, Secost nd Rivier Bech in the 'northern -re nd Lke Worth, Boynton Bech, Acme, nd Delry Bech in-the southern re. There is little noticeble effect from severl other lrge wellfields, including Boc Rton nd the Plm Bech County Systems, which re locted in more trnsmissive portions of the quifer nd within the Lke Worth Dringe District where rechrge from mintined cnls keeps ground wter drwdowns smll. The opposite effect of dringe cnls is evident in the ground wter level depressions in the vicinity of the South Indin River Wter Control District nd North Plm Bech Wter Control District Unit where cnl levels re not mintined. The mss blnces show tht precipittion is by fr the most importnt source of rechrge to the quifer under verge conditions. Rechrge from the Lke Worth Dringe District nd the West Plm Bech Wter Ctchment System re lso significnt. Evpotrnspirtion ccounts for the lrgest loss of ground wter from the study re. It is more significnt in the northern study re, where ground wter levels in undeveloped re re close to lnd surfce, thn in the southern re which is lrgely developed. Well withdrwls re significnt in both the north nd south, lthough more so in the south where withdrwls re greter. Ground wter dringe to cnls is lso significnt. In prticulr, dringe to mintined cnls under verge nnul conditions exceeds rechrge from them over the study re. This does not negte the importnce of these cnls in rechrging the quifer nd mintining ground wter levels in portions of the study re, however, their effect s drins in other res should not be overlooked. Simulted flow nd wter levels indicte low potentil for sltwter intrusion in most of the study re with two exceptions. Simulted wter levels in the southest corner djcent to the Intrcostl rnge from 3.9 to.4 ft NGVD, indicting moderte potentil for sltwter intrusion. Permitted users in this re include the City of Boc Rton (est wellfield), the Boc Rton Hotel nd Club, nd the Royl Plm Ycht nd Country Club. In the northern study re, moderte potentil for intrusion exists ner the Secost North Plm Bech wellfield where simulted wter levels between the wellfield nd the Intrcostl re. ft NGVD. DRY SEASON CONDITIONS (Allocted Wter Use) Conditions in the quifer system t the end of n verge dry seson were pproximted by trnsient, 8 dy simultions using verge dry seson rechrge nd evpotrnspirtion. The simulted heds for verge nnul conditions were used s initil heds for the trnsient runs. The simulted wter levels in lyer under verge dry seson conditions re shown in Figures 6 nd 6. The difference between these wter levels nd those simulted for verge nnul conditions re shown in Figures 63 nd 64. Results for the other lyers re similr nd re therefore not shown. The mss blnces with the modeled inflow nd outflow components t the end of the simultions re given in Tble 4. Simulted declines in ground wter levels during the dry seson re generlly smll, less thn one foot. In portions of the study re where mintined surfce wter systems provide rechrge to the quifer (i.e. the Lke Worth Dringe District, ACME Improvement District, re of the West Plm Bech Ctchment System), ground wter level drops were insignificnt (less thn.5 feet).

153 were gretest, to feet, in the vicinity of severl lrge wellfields, Jupiter, Secost, Lke Worth nd Boynton Bech, where there is no surfce wter rechrge. The mss blnces show totl rechrge nd dischrge decreses during the dry seson. Rinfll is still the most importnt source of rechrge to the quifer system, lthough it mkes up smller percentge of totl rechrge thn it does under verge conditions. Rechrge from mintined surfce wter systems incresed both in terms of totl rechrge volume nd percent of totl rechrge. There ws little chnge in the reltive importnce of the vrious outflows from the quifer. The res with potentil for sltwter intrusion indicted by the simulted ground wter flow nd wter levels re similr to but more extensive thn the res under verge nnul conditions. The re with heds less thn 4 ft. in the southest extends mile further north nd the potentil for intrusion within the re increses with the minimum simulted hed dropping.6 ft. to.9 ft. NGVD. Simulted heds drop.7 ft. to.5 ft. NGVD est of the Secost North Plm Bech wellfield indicting incresed potentil for intrusion there. Further, simulted heds est of the Boynton Bech est wellfield nd the Gulfstrem Golf Club drop to 3.9 nd.6 ft. NGVD respectively indicting moderte potentil for intrusion. 9 AND 8 DAY DROUGHTS (Allocted Wter Use) Trnsient simultions with no precipittion rechrge were used to pproximte severe droughts of 9 nd 8 dys durtion. The runs used verge dry seson ET nd were strted from the hed distribution simulted for verge nnul conditions. The simulted declines in wter levels in lyer resulting from the 9 dy drought re shown in Figures 65 nd 66. Those resulting from the 8 dy drought re shown in Figures 67 nd 68. The mss blnces with the modeled inflow nd outflow components t the end of the simultions re given in Tbles 5 nd 6. The rel distribution of simulted ground wter level declines during droughts with no rinfll rechrge ws similr to the distribution of declines in the dry seson. However, the wter tble drops were greter fter the 9 dy drought thn t the end of the dry seson, nd they becme greter still fter 8 dy drought. Drwdowns during drought conditions becme incresingly significnt in the vicinity of wellfields. Simulted ground wter drwdowns fter 8 dy drought were lrgest (greter thn 6 feet) in the vicinity of the Jupiter nd Secost (Hood Rod) wellfields. There were lso extensive drwdowns (greter thn 4 feet) in the undrined northwest portion of the study re nd in the northest re just south of the Loxhtchee River. The greter decline in these res is probbly cused by two fctors. The res re undrined nd, therefore, hve wter levels closer to lnd surfce thn most of the remining re. Thus evpotrnspirtion, which is function of depth to wter, continues longer nd t higher rte in the undrined res during drought which results in greter wter level declines. Drwdowns of over feet in the Rivier Bech, Royl Plm Bech, Lke Worth, Boynton Bech nd Secost wellfields nd over 3 feet in the Jupiter nd Secost (Hood Rod) wellfields occurred fter 9 dy drought. Drops of over 3 nd 6 feet occurred in the sme wellfields fter 8 dy drought. Ground wter level declines lso occurred in portions of the Lke Worth Dringe District, generlly in the vicinity of chnges in cnl control elevtions. Apprently, cnl rechrge lone is not sufficient to keep up with ground wter underflow from bsins with 3n

160 higher control elevtions to bsins with lower control elevtions under drought conditions. The mss blnces show tht leknce from mintined cnls increses to become the most importnt source of rechrge to the quifer during droughts. In the southern study re, this rechrge is lmost enough to mtch outflow from the quifer system in most res. Relese of wter from quifer storge, primrily through dewtering t the wter tble, mkes up the remining outflow. Wter relesed from storge is more significnt in the northern study re where the mintined surfce wter systems re not s extensive. Evpotrnspirtion nd losses to dringe cnls decrese throughout the study re s result of hed declines. Well withdrwls become more significnt reltive to totl outflow from the quifer, prticulrly in the southern study re where llocted withdrwl rtes pproch evpotrnspirtion rtes. Simulted ground wter flow nd heds long the Intrcostl show high slt wter intrusion potentil in the southestern corner of the study re est of the Boc Rton Hotel nd Ycht Club nd the Royl Plm Ycht nd Country Club during 9 dy drought with llocted wter use. The intrusion potentil becomes higher during 8 dy drought nd the re ffected extends one mile further north to include the re est of the Boc Rton Est Wellfield, The simultions lso show high intrusion potentil est of the Gulf Strem Golf Course wellfield nd during 8 dy drought. The simultions show moderte potentil for slt wter intrusion during 9 dy drought with llocted wter use in the res est of the Boynton Bech Est Wellfield, the Gulf Strem Golf Course, the Boc Rton Est Wellfield, the Delry Bech South Wellfield, nd the Secost North Plm Bech Wellfield. The 8 dy drought simultions with llocted wter use show incresed intrusion potentil in these res nd n dditionl re of moderte potentil est of the Boc Teec Corportion, Highlnd Bech, Secost Burm nd Rivier Bech wellfields. IMPACTS OF ALLOCATED WATER USE The impcts of llocted ground wter withdrwls on the Surficil Aguifer System under verge nnul, verge dry seson nd 9 dy drought conditions were determined by compring the results of simultions with the withdrwls to equivlent simultions without the withdrwls. The simulted drwdowns in model lyer cused by llocted wter use under verge nnul conditions re shown in Figures 69 nd 7. Drwdowns under verge dry seson nd 9 dy drought conditions re similr s re drwdowns in the lower model lyers. The lrgest simulted drwdowns in the study re, greter thn feet, occur t the Lke Worth wellfield. Substntil drwdowns lso occurred t the Boynton Bech, Delry Bech, Jupiter, nd Secost wellfields which hd drwdowns greter thn 8, 4, 4 nd 4 feet respectively. Wellfield drwdowns were smller in the more trnsmissive res of the quifer nd in res with surfce wter rechrge to the quifer. These res re lrgely concurrent in the southern study re where the Lke Worth Dringe District overlies the Biscyne quifer. However, drwdowns still exceed feet t the Boc Rton, Boynton #6 nd Plm Bech County System wellfields in these re. Comprison of the mss blnce results (Tbles 3 nd 7) showed tht the ground wter withdrwls cuse decrese in outflow from evpotrnspirtion nd 39

Ground wter withdrwls re significntly incresing the potentil for slt wter intrusion long the cost in much of the study re south of C-5. Simulted costl drwdowns south of Highlnd Bech re typiclly to ft. s result of llocted withdrwls by the Boc Rton Hotel nd Ycht Club, the Royl Plm Ycht nd Country Club, Boc Rton, Highlnd Bech, nd the Boc Teec Corportion. Drwdowns re lso to feet est of the Delry Bech wellfield nd re to 6 ft. est of the Boynton Bech nd Gulfstrem Golf Club wellfields. North of C-5, presently llocted withdrwls hve significnt effect on slt wter intrusion potentil only in the res est of the Secost North Plm Bech, Secost Burm, nd Rivier Bech estern wellfields where simulted costl drwdowns re to ft. Mny of the llocted withdrwls in these problem res re being reviewed by the SFWMD through the wter use permitting process. Simultions show tht potentil environmentl impcts on wetlnds resulting from presently llocted withdrwls re limited primrily to the est hlf of the Loxhtchee Slough in the northern study re. Simulted cumultive drwdowns from the Secost Hood Rod wellfield nd the Jupiter wellfield t the southest edge of the slough re pproximtely 3 feet under verge nnul conditions nd ner 4 feet under 9 dy drought conditions. Cumultive drwdowns under the northest corner of the slough re to ft. under the sme conditions. Simulted drwdowns of.5 ft. or more extend pproximtely one mile beyond the slough's estern boundry under verge conditions nd one nd hlf miles beyond it under drought conditions. Bsed on the regionl wetlnd mp, there re lso potentil environmentl impcts ner the Prtt Whitney wellfield. A more rigorous definition of wetlnds in tht re will be necessry to better define the impcts. EFFECTS OF MAINTAINED SURFACE WATER SYSTEMS (Allocted Wter Use) The importnce of surfce wter systems with mintined wter levels in rechrging the quifer system, diminishing ground wter drwdowns, nd preventing sltwter intrusion ws evluted by compring the results of simultions with nd without rechrge from these systems. Allocted wter use simultions without surfce wter system rechrge (except from the boundry cnls, C-5, L-8, Hillsboro, nd WCA-, since boundry conditions were not chnged) were run for verge nnul conditions, dry seson conditions, nd 9 dy drought. Since the mintined cnl systems provide dringe s well s rechrge for the quifer system, they were represented s drins (with cut-off elevtions equl to the cnl mintennce elevtions) in the no rechrge simultions. The West Plm Bech Wter Ctchment System ws not represented in the simultions since it provides little ground wter dringe. Simulted ground wter levels for verge nnul conditions with no rechrge from mintined surfce wter systems re shown in Figures 7 nd 7. In portions of the study re, these levels re significntly lower thn simulted levels for the sme conditions with surfce wter rechrge. This is cler in Figures 73 nd 74 which show the decline in wter levels under verge nnul conditions when surfce wter rechrge is eliminted. Surfce wter rechrge hs the gretest influence on ground wter levels in the vicinity of lrge ground wter withdrwls. Ground wter levels ner the Boc Rton, Boynton Bech, ACME Improvement District, nd Secost (Hood Rod) wellfields re three to four feet higher with 43

169 surfce wter rechrge thn they would be without it under verge nnul conditions. Rechrge effects re lso influentil in the vicinity of the West Plm Bech Wter Ctchment System where surfce wter rechrge elevtes ground wter levels to 3 feet under the wter ctchment re nd to feet in the vicinity of Lke Mngoni nd Cler Lke. Surfce wter rechrge to the quifer becomes even more significnt under dry seson nd drought conditions. The generl res influenced by the rechrge re the sme s under verge nnul conditions, however, the totl re ffected is lrger nd the degree of influence is greter. This is illustrted in Figures 75 nd 76 which show the dditionl simulted ground wter level declines t the end of the dry seson resulting from eliminting surfce wter system rechrge nd in Figures 77 nd 78 which show the nlogous declines fter 9 dy drought. The mss blnces for the no surfce wter rechrge simultions re given in Tbles 8, 9, nd for verge nnul conditions, dry seson conditions, nd 9 dy drought respectively. In ll the mss blnces, evpotrnspirtion nd ground wter dringe to cnls decresed when surfce wter rechrge ws eliminted. This is direct effect of the lowered wter levels discussed bove. The effect ws prticulrly pronounced in the southern study re where evpotrnspirtion decreses rnged from 3% for verge nnul conditions to 66% for the 9 dy drought nd decreses in dringe into LWDD cnls rnged from 4% for verge nnul conditions to 7% for the 9 dy drought. Mintined surfce wter systems re generlly considered quite importnt in preventing slt wter intrusion. The no surfce wter rechrge simultions verify tht this is true for certin portions of the study re under drought conditions, however, it is not uniformly true for the entire study re under present conditions. In the southern study re, the LWDD cnl network does little to reduce sltwter intrusion potentil north of C-6. However, the network does reduce the potentil for slt wter intrusion during the dry seson nd droughts long the cost south of C-6 where simulted ground wter levels without surfce wter rechrge in some res re less thn 4 ft. NGVD indicting moderte potentil for slt wter intrusion nd in other res re less thn.6 ft. NGVD indicting probble intrusion occurrence. The simultions show tht rechrge from the cnls rises ground wter levels in the re from. to.6 ft. with n verge of bout.9 ft. under dry seson conditions nd.4 to 3.7 ft. with n verge of bout.5 ft. under 9 dy drought conditions. These increses significntly reduce the potentil for intrusion long most of this stretch lthough there re res where intrusion remins probble or moderte intrusion potentil still exists even with the rechrge (see discussions under verge nnul, verge dry seson, nd 9 nd 8 dys drought sections). Cnl rechrge hs the gretest influence in the vicinity of the Boynton Bech est wellfield where it increses wter levels lmost 4 ft. under 9 dy drought conditions nd reduces the potentil for intrusion from probble to moderte. In the northern study re, mintined systems hd no significnt effect on the slt wter intrusion potentil. Cler Lke nd Lke Mngoni, the closest mintined surfce wter bodies to the ocen, do keep ground wter levels foot or so higher long the cost under drought conditions thn they would be otherwise. However, since the increse is from 9 or to or ft. NGVD, the effect on intrusion potentil is negligible. 48

This would undoubtedly hve significnt impct on the wetlnds. BUILDOUT PUBLIC WATER SUPPLY USE Buildout public wter supply use estimtes for the model simultions were mde by the SFWMD Lnd nd Wter Plnning Division (Lshu, written communiction, 988).

An verge per cpit wter use 7 gpcd ws estimted for the study re bsed on this dt fter it ws djusted for some of the very high users. The estimted totl buildout popultion in the study re is.58 million bsed on the Plm Bech County Metropolitn Plnning Orgniztion Trffic Anlysis Zones (TAZ) dt. This popultion ws distributed mong the public wter suppliers s shown in Tble using the TAZ dt nd utility service res. Tble lso gives the estimted buildout per cpit nd totl wter demnd by utility. Projected public wter supply use in the study re t buildout is 9.6 bgy. This use is firly evenly distributed between the north (5.69 bgy) nd the south (56.93 bgy) portions of the study re. Some utilities presently hve lloctions which exceed the projected buildout demnds (see Tble ). This is generlly due to differences between the per cpit demnd rtes used herein nd the rtes used when the permits were issued. In these cses, the llocted wter use ws used in the buildout simultions. IMPACTS OF BUILDOUT PUBLIC WATER SUPPLY USE The impcts of incresing public wter supply use to projected buildout levels under verge nnul, verge dry seson nd 9 dy drought conditions were determined by compring the results of simultions with llocted wter use to equivlent simultions with projected buildout public wter supply use. Surfce wter system mngement nd non-public wter supply ground wter use were not chnged for the buildout simultions. However, the rinfll rechrge fctors were djusted to reflect projected chnges in lnd use t buildout (see mps in Appendix E). Projected public wter supply pumpge ws distributed to existing nd proposed utility wellfields bsed on informtion provided by the SFWMD Resource Control Deprtment.

Simulted ground wter drwdowns (model lyer ) in the study re s result of incresing public wter supply use to projected buildout levels under 9 dy drought conditions re shown in Figures 79 nd 8. Drwdowns under other conditions nd in other lyers re similr nd re therefore not shown. Ground wter level drwdowns from incresed pumpge t buildout re restricted to the vicinity of the new wellfields or wellfields with incresed pumpge. Projected drwdowns re lrger in the north study re where the pumpge increses re greter nd trnsmissivities re lower thn in the south. The lrgest simulted drwdowns, 8 ft., re t the Jupiter nd Secost Hood Rod wellfields. Firly lrge drwdowns, bout 6 ft., re lso projected t the Secost Burm nd Secost North Plm Bech wellfields. Smller drwdowns, to 4 ft., re projected for the Royl Plm Bech, Lke Worth, Acme, nd the Plm Bech County System wellfields (,, 3, nd 9). The mss blnce results for the buildout runs, given in Tbles 3 to 5, show increses in surfce wter rechrge to the quifer, decreses in ground wter dringe to cnls, nd decreses in evpotrnspirtion when ground wter withdrwls re incresed to buildout levels. These chnges re smll reltive to the overll mss blnce components lthough they my be importnt on locl scle. The buildout increses ffected slt wter intrusion nd environmentl impct potentil only ner the Jupiter nd Secost wellfields. The increses cused pproximtely 3 feet of dditionl drwdown t the northest corner of the Loxhtchee Slough nd 4 feet of dditionl drwdown t the southest corner. These drwdowns would be expected to hve dverse impcts on the slough. Incresed potentil for slt wter intrusion occurs est of the Secost North Plm Bech wellfield where simulted heds drop to feet long the cost s result of the pumpge increses. These drwdowns increse the slt wter intrusion potentil in the re from moderte to probble. Fortuntely, Jupiter lredy plns to shift its dditionl withdrwls to the Floridn quifer which should llow them to meet their demnd without cusing dverse impcts. It ppers tht Secost Utilities will need to seek lterntives s well if they re to meet their buildout demnds without dverse environmentl impcts or slt wter intrusion problems. 59

187 GROUND WATER DEVELOPMENT POTENTIAL INTRODUCTION The development potentil of the quifer systems in the study re is determined by numerous fctors including quifer productivity, mbient wter qulity, potentil for wter qulity degrdtion, potentil for dverse impcts on existing users, nd potentil for dverse impcts on the environment. To compre the reltive development potentil in the Surficil nd Floridn Aquifer Systems in the study re, four levels of development potentil - good, moderte, fir, nd poor - hve been defined bsed on spects of ll the bove fctors except one, the potentil for dverse impcts on existing users. The definitions of potentil development re rbitrry since they re intended primrily to provide bsis of comprison of reltive development potentil. Adverse impcts on existing users were not considered since they re dependent on knowledge of pumping rtes nd exct well loctions which ws beyond the scope of this study. These impcts re best ddressed through the SFWMD wter use permitting process. Aspects of mbient wter qulity nd wter qulity degrdtion relted to lndfills were lso not ddressed since the definition of existing contminnt plumes nd their possible fte with or without remedil ction is lso beyond the scope of this study. However, the loctions of lndfills in the study re re shown with the potentil development res on Pltes nd 3. Lndfill impcts should be ddressed on n individul bsis through the wter use permitting process. The criteri for determining the development potentil for the quifers is summrized in Tble 6. Ares with good development potentil re defined s hving high productivity (t lest 4 ft. of Biscyne quifer present) nd mbient ground wter which my be treted to potble stndrds with methods conventionlly used by public wter suppliers. Additionlly, the potentil for dverse environmentl impcts or degrdtion of wter qulity s result of withdrwls in these res is considered miniml. The criteri for res with moderte development potentil differs from those for res with good potentil only in terms of quifer productivity which must be moderte (t lest ft. of Biscyne quifer or more thn ft. of production zone present) rther thn high. Ares with fir development potentil encompss ll res excluded from the good nd moderte potentil ctegories becuse of low productivity. They lso include res where the mbient ground wter hs totl dissolved solids (TDS) content of less thn, mg/ nd is tretble to potble stndrds using reverse osmosis. Ares where the potentil for dverse environmentl or wter qulity impcts s result of withdrwls is questionble t this time (i.e. res djcent to wetlnds where impcts depend hevily on withdrwl quntities) re lso included in the fir potentil ctegory. All res not meeting the criteri for good, moderte or fir development potentil becuse of likely dverse environmentl impcts or wter qulity degrdtion s result of withdrwls re grouped into the poor development potentil ctegory. SURFICIAL AQUIFER SYSTEM The ground wter development potentil of the Surficil Aquifer System s defined by the criteri described bove is shown on Plte 3. The re of good 66

189 development potentil extends north from the Plm Bech-Browrd County line to pproximtely Okeechobee Boulevrd nd covers much of the south study re. The extent of the good development re north of SR 8 is limited primrily by the extent of the thick portion of the Biscyne quifer. South of SR 8 it is generlly limited by the potentil for withdrwls resulting in dverse impcts on the wetlnds ner nd in WCA- to the west nd in incresed potentil for costl sltwter intrusion to the est. Most of the moderte development potentil re in the Surficil Aquifer System lies long the fringes of the good potentil res where the Biscyne quifer is less thn 4 but greter thn feet thick. Other res of moderte development potentil in the study re re quite limited since most of the res of the Surficil Aquifer System with greter thn ft. of production zone re under the West Plm Bech Wter Ctchment Are where wter tble drwdowns s result of ground wter development re environmentlly undesirble. Ares of fir development potentil re spred throughout the study re. One mile strips djcent to WCA- nd the WPBWCA were clssified in the fir ctegory becuse dverse environmentl impcts resulting from development in these res re dependent on the quntity nd configurtion of ground wter withdrwls nd re therefore uncertin. Ares est of the Turnpike in the north re nd djcent to the estern edge of the moderte development potentil res re in the fir ctegory due to their low productivity. Most remining fir development potentil res hve both low productivity nd mbient wter qulity which is not conventionlly tretble to potble stndrds. Reverse osmosis is required to produce potble wter in these res. However, wter qulity degrdtion s result of upconing will need to be ddressed in development of these sections since wter qulity typiclly degrdes with depth. Production wells in these res re often shllow to tke dvntge of the better wter qulity ner the surfce. However, the upconing of the deeper poorer qulity wter s result of the shllow withdrwls ultimtely degrdes the shllow wter qulity. This could probbly be prevented by using the deeper ground wter with pproprite tretment methods. The entire costl mrgin of the Surficil Aquifer System is in the poor development ctegory becuse dditionl withdrwls there re expected to significntly increse the potentil for sltwter intrusion. The other res of the Surficil quifer with poor development potentil re under wetlnds (the Corbett Wildlife Refuge, the Loxhtchee Slough, the West Plm Bech Wter Ctchment Are, the wetlnds djcent to WCA-) where the wter tble drwdowns likely to result from ground wter development re undesirble. THE FLORIDAN AQUIFER SYSTEM The upper Floridn quifer underlying the study re hs fir development potentil. Its productivity is low compred to much of the Surficil Aquifer System nd its wter is not conventionlly tretble to potble stndrds. There re two primry concerns in developing the upper Floridn Aquifer System. First, ground wter qulity is generlly better in the upper zones of the system thn in the lower ones. Thus, the potentil for wter qulity degrdtion in the upper zones s result of withdrwl induced upconing of poorer qulity wter from the lower zones will hve to be considered if the Floridn is developed. The second concern, is the potentil for dverse impcts on existing Floridn users in Mrtin County. Since these users re not permitted to instll pumps on their wells, the impcts of 68

190 drwdowns from withdrwls in the study re would be difficult to mitigte if they extend under the Plm Bech-Mrtin County line nd reduce the flow rte of Mrtin County Floridn wells. The lower Floridn quifer underlying the study re hs poor development potentil since its mbient ground wter hs totl dissolved solids content of greter thn, mg/. 69

191 RESULTS AND CONCLUSIONS. The most productive zone of the Surficil Aquifer System in estern Plm Bech County is the northern extension of the Biscyne quifer. It is composed primrily of highly solutioned limestone with n verge hydrulic conductivity of pproximtely 6 ft./dy. The extent of the Biscyne quifer in the study re is irregulr (Plte 6). It extends from the Plm Bech - Browrd county line north to pproximtely Hood Rod where it pinches out. It lso generlly pinches out before reching the cost to the est nd WCA- to the west. The Biscyne quifer is thickest long its centrl portion between the turnpike nd Militry Tril where it is 4 to ft. thick. The quifer thins to typiclly less thn 4 ft. thick north of the M cnl.. The Biscyne quifer is surrounded in most of the study re by modertely productive intervl of sndy shell, modertely solutioned limestone, nd modertely to well solutioned sndstone with n verge hydrulic conductivity of pproximtely 5 ft./dy. Most withdrwls in the study re north of C-5 re from either this modertely productive intervl or the Biscyne quifer, hence, the two re referred to collectively s the production zone. The production zone underlies most of the northern study re; it is known to be bsent only in smll re est of Militry Tril between 45th St. nd Northlke Blvd. (Plte 9). The production zone in the northern re is thickest, ft. or more, ner the turnpike nd Okeechobee Blvd. just north of C-5 (Plte 9). In the rest of the northern re, it is generlly thickest ( ft. or more) long north - south strip extending west 3 to 6 miles from the turnpike. It is lso greter thn ft. thick est of the turnpike in the re between Donld Ross Rod nd PGA Blvd. 3. The most importnt source of rechrge to the Surficil Aquifer System is rinfll. Under verge conditions, with presently llocted wter use, rinfll provides pproximtely 85% of the totl nnul quifer rechrge in the study re. About n dditionl 3% is provided by lekge from the West Plm Bech Wter Ctchment Are (3%) nd cnl systems with mintined wter levels (%). Over hlf of the totl rechrge from mintined cnl systems comes from the LWDD system which covers close to hlf the study re. The remining nnul rechrge comes primrily from inflow to the study re from WCA-. 4. The lrgest ground wter losses from the Surficil Aquifer System in the study re result from evpotrnspirtion which ccounts for pproximtely 6 percent of totl nnul losses under verge nnul conditions with llocted wter use. Lekge to cnls, the next most importnt dischrge from the quifer, ccounts for n dditionl percent of the losses. Close to hlf (4 percent) of the ground wter dischrge to cnls occurs in the LWDD system. Allocted withdrwls by ground wter users mke up nother 5 percent of the estimted verge nnul quifer losses. Remining losses come primrily from lekge in the C-5 nd Hillsboro cnls. Ground wter underflow out of the study re to the Intrcostl Wterwy is smll, less thn percent of the totl quifer losses. 5. Simulted flow nd ground wter levels indicte potentil for sltwter intrusion in severl res long the cost under typicl conditions. The gretest potentil in the study re exists long the southernmost 5 miles of 7

192 cost where simulted ground wter levels t the end of the dry seson rnge from.8 to 3.8 ft. Permitted users likely to be impcted by intrusion in this re re the City of Boc Rton, the Boc Rton Hotel nd Club, nd the Royl Plm Ycht nd Country Club. Potentil for sltwter intrusion during the dry seson lso exists est of the Secost North Plm Bech, Gulfstrem Golf Club, nd the Boynton Bech Est wellfields where simulted wter levels t the end of the dry seson re less thn 4 ft. 6. Severe droughts, when there is no rinfll rechrge reching the quifer, cuse decresed ground wter flow towrd the cost nd declines in costl ground wter levels. This mkes sltwter intrusion likely in portions of the study re during extended droughts if ground wter withdrwls re not reduced or shifted inlnd. Model simultions show high potentil for intrusion occurring long the southernmost mile nd hlf of cost in the vicinity of the Boc Rton Hotel nd Country Club nd the Royl Plm Ycht nd Country Club during 9 dy drought with llocted wter use. Intrusion potentil increses during simulted 8 dy drought nd extends one mile further north to include the re est of the Boc Rton wellfield. Intrusion is lso likely est of the Gulfstrem Golf Course wellfield during 8 dy drought. 7. Rechrge from surfce wter systems with mintined wter levels keeps ground wter levels in much of the study re significntly higher thn they would be otherwise. This rechrge hs the gretest influence on ground wter levels in the vicinity of lrge wellfields. Simulted ground wter levels ner the Boc Rton, Boynton Bech, nd Acme Improvement District wellfields re incresed 3 to 4 ft. by surfce wter rechrge under typicl conditions. Surfce wter rechrge effects re lso significnt in the vicinity of the West Plm Bech Wter Ctchment Are where the rechrge rises simulted ground wter levels to 3 ft. under the wter ctchment re nd to ft. ner Cler Lke nd Lke Mngoni under typicl conditions. Surfce wter rechrge to the quifer is even more significnt under drought conditions when little or no rinfll reches the wter tble. Under these conditions, lekge from surfce wter systems with mintined wter levels becomes the min source of rechrge to the quifer when the surfce wter levels cn be mintined. If the levels cnnot be mintined (i.e. wter from Lke Okeechobee or the Wter Conservtion Ares is not vilble), there is little quifer rechrge nd ground wter levels will decline ccordingly s wter is removed from quifer storge. Aquifer rechrge from LWDD cnls reduces the potentil for costl sltwter intrusion south of C-6 during dry seson nd drought conditions when the cnl design levels cn be mintined. Model simultions show tht rechrge from the cnls under these conditions rises costl ground wter levels in tht re from. to.6 ft. with n verge of bout.9 ft. during the dry seson nd from.4 to 3.7 ft. with n verge of.5 ft. during 9 dy drought. 8. Totl permitted ground wter withdrwls in the study re s of Februry 989 were pproximtely 97 billion gllons per yer. Two thirds of this is for public wter supply use nd the reminder is primrily for griculturl, lndscpe nd golf course irrigtion. The llocted withdrwls result in ground wter level drwdowns in the study re which re gretest in res where the quifer trnsmissivity is lowest nd where there is little rechrge

193 from surfce wter systems. The lrgest projected drwdowns in the study re, greter thn ft., occur t the Lke Worth wellfield. Substntil drwdowns re lso expected t the Boynton Bech, Delry Bech, Jupiter, nd Secost wellfields where projected drwdowns re pproximtely 8, 4, 4, nd 4 ft. respectively. Ground wter withdrwls pper to be incresing the potentil for slt wter intrusion long the cost in much of the study re south of C-5. Simulted costl drwdowns s result of withdrwls re to ft. south of Highlnd Bech nd est of the Delry Bech wellfields nd to 6 ft. ner the Boynton Bech nd Gulfstrem wellfields. North of C-5, presently llocted withdrwls pper to significntly ffect sltwter intrusion potentil in the res est of the Secost North Plm Bech, Secost Burm, nd Rivier Bech Estern wellfields where simulted costl drwdowns re to ft. It is likely tht llocted withdrwls re cusing dverse impcts in the estern portion of the Loxhtchee Slough where simulted cumultive drwdowns from llocted withdrwls t the Secost Hood Rd. wellfield nd the Jupiter wellfield re to 3 ft. under verge conditions nd 3 to 4 ft. under drought conditions. 9. Public wter suppliers in the study re south of C-5 should be ble to meet their buildout demnds with ground wter from the Surficil Aquifer System, provided wter conservtion techniques re prcticed, wellfields re properly locted, nd ground wter qulity is protected. There is lrge re with good ground wter development potentil within the Biscyne quifer in the south. Becuse the Biscyne quifer is so prolific, utilities with existing wellfields in the good development re should be ble to meet their buildout demnd. Further, utilities with wellfields thretened by sltwter intrusion should be ble to move their wellfields inlnd to the good re, if necessry, with miniml impcts on the ground wter system. In the study re north of C-5, Jupiter nd Secost re unlikely to be ble to meet their future demnds from the Surficil Aquifer System lone. Incresing withdrwls to buildout levels t their existing wellfields is expected to cuse undesirble drwdowns under wetlnds nd incresed potentil for costl sltwter intrusion. Withdrwls from lterntive loctions in the Surficil Aquifer System est of the West Plm Bech Wter Ctchment Are nd Loxhtchee Slough re limited by the sme fctors. The upper Floridn quifer is one possible lterntive source for these utilities t this time.. The best potentil ground wter development re in estern Plm Bech County occurs entirely within the Biscyne quifer nd extends north from the Plm Bech - Browrd county line to pproximtely Okeechobee Blvd. with n irregulr est - west extent tht generlly includes the re between the turnpike nd Militry Tril (Plte 3). This re is limited to where the Biscyne quifer is greter thn 4 ft. thick nd ground wter withdrwls re unlikely to induce sltwter intrusion or cuse dverse environmentl impcts. 7

194 Potentil for ground wter development of the Surficil Aquifer System is poor in severl prts of the study re. Additionl development of the quifer long the costl mrgin is undesirble due to the likelihood of incresing the potentil for sltwter intrusion there. Development djcent to WCA-, the West Plm Bech Wter Ctchment Are, or the Loxhtchee Slough is undesirble due to the thret of dverse impcts on the wetlnds. Development west of C-8 in the Corbett Wildlife Mngement Are is lso undesirble for this reson. 73

195 RECOMMENDATIONS. Additionl Surficil Aquifer System withdrwls should be denied if they re likely to decrese ground wter levels or sewrd ground wter flow long those portions of the cost where the potentil for sltwter intrusion under dry seson nd drought conditions is lredy significnt. Existing permits for ground wter use in these res should continue to be re-evluted through the SFWMD wter use permitting process nd permitted lloctions should be reduced nd/or withdrwls shifted further inlnd where possible. Stringent slt wter intrusion monitoring progrms including concurrent wter level nd chloride mesurements from t lest two sets of multi-level observtion wells instlled in line between the withdrwl fcilities nd the cost should be required of ll ground wter permittees in the costl res thretened by intrusion. This will provide wrning of intrusion before it reches the wellfields nd provide better dt on the sltwter intrusion process.. Wter levels in the LWDD costl bsins should continue to be mintined. If fesible, the control elevtion in the 4.5 ft NGVD bsin should be rised to increse the surrounding ground wter levels nd help prevent sltwter intrusion. When surfce wter deliveries to the LWDD system re limited, priority should be given to mintining cnls levels in the costl bsins becuse of their importnce in preventing sltwter intrusion. 3. If the Loxhtchee Slough is to be protected, no further withdrwls which cuse drwdowns underneth it should be permitted. Drwdowns from presently llocted withdrwls re lredy expected to extend under the slough nd even smll dditionl withdrwls will be dding to the cumultive impct potentil. 4. Secost Utilities should either seek new Surficil quifer wellfield loctions or n lterntive source to provide for ny demnds exceeding their present lloction becuse incresing withdrwls t their existing wellfields will dversely impct wetlnds nd increse the potentil for costl sltwter intrusion. Options for new Surficil quifer wellfield sites in the northern study re re quite limited since most of the re hs poor ground wter development potentil due to probble wetlnd impct nd sltwter intrusion problems. The Floridn quifer my be the best lterntive source if the Floridn withdrwls cn be locted such tht drwdown impcts on other permitted Floridn users re miniml. 5. Jupiter should continue with their plns to use the Floridn quifer for their dditionl withdrwls since this study confirms tht these demnds cnnot be met from the Surficil Aquifer System without dverse impcts. 6. The development potentil of the Floridn quifer in the study re should be explored further. Studies should emphsize determintion of the trnsmissivity of the upper Floridn quifer, the wter qulity vrition with depth within the Floridn quifer, nd the degree of connection between the different wter qulity zones. This informtion should be used to evlute likely wter qulity deteriortion nd djcent user impcts if the Floridn is developed s ground wter source. 74

196 7. Stormwter retention for infiltrtion to the quifer should be required or encourged to the gretest degree possible since rinfll is the mjor source of rechrge to the Surficil Aquifer System. Similrly, reduction of pervious re during lnd development should be minimized to the extent possible since rinfll cnnot infiltrte impervious res to rechrge the quifer. 8. The ground wter development potentil mp of the Surficil Aquifer System (Plte 3) should be used s guide in locting new wells/wellfields. Preference should be given to the good zone over the moderte zone nd to the moderte zone over the fir zone when possible. Withdrwls should not be mde from the poor development potentil zone unless they re smll enough to preclude the dverse impcts nticipted in the zone. 9. The models developed in this study should continue to be used in the wter use permitting nd plnning process for regionl problems. Where finer scle is needed, the models should be used to provide boundry conditions. The models should be refined nd updted s dditionl dt become vilble. In doing this, emphsis should be plced on improving confidence in the prmeters to which the models re most sensitive including cnl conductnce, rinfll rechrge nd evpotrnspirtion.. All ground wter level monitoring wells in the study re, including wells monitored s prt of wter use permit requirements, should be surveyed to NGVD. This will llow ccurte comprison of wter levels throughout the county. Ground wter monitoring progrms should include mesurements of key cnl wter levels since the ground wter nd surfce wter systems re so closely relted. Additionlly, regionl smpling should be coordinted with wter level nd slt wter intrusion monitoring smpling performed by wter use permittees. This is prticulrly importnt since sensitivity runs show tht the models re most sensitive to clibrtion prmeters in the vicinity of wellfields. 75
