The information is arranged by source (ground or surface), category of use, and county. Water use covers all water uses from ground or surface water sources and is expressed in million gallons per day (mgd). Values are the average annual quantities withdrawn and are rounded to the nearest 1, gallons (.1 mgd). The total amount of water used in SJRWMD in 1992, including fresh and saline water, was 3, mgd. Of that total, 1, mgd, or 45 percent, was fresh water. The total surface water use for SJRWMD was 2,38.9 mgd, of which 1, mgd was saline and mgd was fresh. The total amount of ground water withdrawn in SJRWMD was 1,42.67 mgd. All ground water was fresh water. The largest use of fresh ground water was for public supply 49.8 mgd, or 39 percent of the total fresh ground water use in SJRWMD, followed closely by agricultural irrigation mgd, or 33 percent of the total. The largest use of fresh surface water was for agriculture mgd, or 6 percent of the total fresh surface water use in SJRWMD. Most surface water used was saline water, used primarily for thermoelectric power generation (1, mgd). Brevard County had the largest total water use, at 1, mgd, and Indian River County had the highest total freshwater withdrawal, at mgd. V

10 Introduction INTRODUCTION Water use data have been published annually by the St. Johns River Water Management District (SJRWMD) since This report assesses water use in SJRWMD for 1992; it presents the total quantities of water used. The information is arranged by source (ground or surface), category of use, and county. Water use covers all water uses from ground or surface water sources and is expressed in million gallons per day (mgd). Values are the average annual quantities withdrawn and are rounded to the nearest 1, gallons (.1 mgd). SJRWMD includes all or part of 19 counties in northeast Florida (Figure 1).

12 Water Use Categories WATER USE CATEGORIES PUBLIC SUPPLY Water use information is reported for seven categories of use: Domestic self-supply Commercial/industrial self-supply Agricultural irrigation Recreational irrigation Thermoelectric power generation Abandoned artesian wells The public supply category consists of water supplied by utilities to homes and industries. The reported amounts are a minimum, because some utilities report water withdrawals from the ground water system as water enters the treatment plant and others report only the amount of water delivered from the plant, which can be less than the actual withdrawals. Utilities that serve 4 or more people or that withdraw more than.1 mgd from ground or surface water sources are included in the public supply category. These data come from utility records and are estimated to the nearest.1 mgd. One hundred ninety public supply utilities served 2,785,17 people in 1992, or 84 percent of the total population in SJRWMD (Table 1 and appendix). The rest of the population is assumed to use domestic self-supplied systems. County, city, and municipal population data are estimated from Florida Bureau of Economics and Business Research figures (University of Florida 1993a, 1993b). data are estimated from the average service connections reported in the utility records multiplied by the average number of people per household (University of Florida 1991). 3

14 Water Use Categories DOMESTIC SELF-SUPPLY The domestic self-supply category includes water withdrawn by individual domestic wells or provided by utilities that serve fewer than 4 people. All domestic self-supplied water is assumed to be ground water, and it is assumed that individual wells are drilled into the easiest accessible aquifer that could produce the water. Small utilities and domestic wells are not inventoried, so water use in this category is estimated from population and per capita water use figures. Populations are based initially on the 199 census data. SJRWMD follows watershed boundaries and not county boundaries; therefore, some counties are only partially included in SJRWMD. SJRWMD population figures for these counties are based on estimated population percentages contained in Florence (1994). Domestic self-supplied water use is derived by (1) subtracting the number of people served by public supply systems from the water use population of the county, to obtain a domestic selfsupplied population, and (2) multiplying the result by the county per capita water use. Per capita water use is derived by dividing the public supply water use by the public supply population. COMMERCIAL/INDUSTRIAL SELF-SUPPLY The commercial/industrial self-supply category consists of the larger commercial and industrial users not served by public supply utilities. The commercial category includes businesses and institutions, such as government facilities, military installations, schools, prisons, hospitals, and recreational facilities. The industrial category includes mining, processing, and manufacturing facilities; it does not include water used for power generation by thermoelectric power plants. Only commercial/industrial self-supplied facilities that used more than.1 mgd of ground or surface water were inventoried. In 1992, 58 industrial users and 43 commercial users, including 41 institutions, were included in this report. Water used for 5

15 ANNUAL WATER USE SURVEY: 1992 transporting materials from the mine pit to the plant and for dewatering mining pits is considered conveyance and was not included in estimates of water use. The data for this category are based on reported water use or permitted allowances. The data were collected using information from the consumptive use permits (CUP) issued by SJRWMD to the facilities and information from monthly operating reports received by SJRWMD, the Florida Department of Environmental Protection (DEP), or the Florida Department of Health and Rehabilitative Services (HRS). Industries not reporting to DEP or SJRWMD were contacted by SJRWMD staff. AGRICULTURAL IRRIGATION The agricultural water use category consists of estimated water withdrawals from ground or surface sources for agricultural crop irrigation. Estimates of the acreage planted in various crops are multiplied by estimates of the water necessary to irrigate those crops per acre. Water use for irrigation is assessed by crop, because different crops require different amounts of irrigation (USDA 197). There are 31 categories assessed, and these are divided into five groups (Table 2): Vegetable crops Fruit crops Field crops Ornamentals and grasses Miscellaneous agricultural (includes livestock watering and lake augmentation for fish farming) The acreage data are supplied primarily by the Cooperative Extension Service of the Institute of Food and Agricultural Sciences at the University of Florida, supplemented by information from SJRWMD CUP files and the Florida Department of Agriculture and Consumer Services (FDACS 1993a, 1993b, 6

16 Water Use Categories Table 2.

The Florida Crop and Livestock Reporting Service provides counts of livestock, which are multiplied by a specified amount of water used per head (FDACS 1993d). The estimates of irrigation necessary per acre for each crop are calculated using the modified Blaney-Criddle irrigation model (USDA 197) and data from the SJRWMD Benchmark Farms irrigation monitoring program (Singleton 1993), supplemented by other information from the U.S. Department of Agriculture Soil Conservation Service (USDA 197, 1982) and the National Oceanographic and Atmospheric Administration (NOAA 1992). 7

17 ANNUAL WATER USE SURVEY: 1992 RECREATIONAL IRRIGATION The recreational irrigation category includes water used to irrigate turf grass for golf courses and other types of recreational areas, such as football and soccer fields. In previous Annual water use survey reports, turf grass irrigation was included in the agricultural water use category as turf grass (golf) and turf grass (other). All of the recreational water use was assumed to be fresh water. The acreage data are supplied primarily by the Cooperative Extension Service of the Institute of Food and Agricultural Sciences at the University of Florida, supplemented by information from SJRWMD CUP files and the Florida Department of Agriculture and Consumer Services (FDACS 1993a, 1993b, 1993c). The estimates of irrigation necessary per acre for each crop are calculated using the modified Blaney-Criddle irrigation model (USDA 197). THERMOELECTRIC POWER GENERATION The thermoelectric power generation category of water use consists of water used by power plants primarily for cooling. These figures are derived from information in the SJRWMD CUP files or from data supplied by the power companies to SJRWMD, DEP, or HRS in monthly operating reports. In 1992, water use data were collected for 12 self-supplied thermoelectric power plants. ABANDONED ARTESIAN WELLS The abandoned artesian wells category includes water flowing from abandoned artesian wells. According to available data, all abandoned artesian wells are supplied by the system. Water flowing from abandoned artesian wells is estimated based on an average of metered flow from monitored wells multiplied by an estimated number of wells. For counties where known flows exist, the average of the known flows in that

18 Water Use Categories county is used to estimate flow from the wells of unknown flow. For counties where no flows have been measured, the districtwide average for all wells of known flow is used. In 1992, the districtwide average for all wells of known flow was.142 mgd per well (Steele 1993). In previous Annual water use survey reports, the estimated amount of water flowing from abandoned artesian wells was included in the miscellaneous category of water use. Previous abandoned artesian well reports are dated by the year in which the fiscal year ends (e.g., October 1991 through September 1992 is in the 1992 report). 9

19 ANNUAL WATER USE SURVEY: WATER USE BY SOURCE TOTAL WATER USE Water can be withdrawn from surface waterbodies or from the various aquifers within SJRWMD. There are three ground water aquifer systems in SJRWMD: the surficial, the intermediate, and the Floridan. Most ground water used in SJRWMD comes from the system. For the purposes of this report, fresh water (ground or surface) is defined as any water containing 1, milligrams per liter (mg/l) or less of total dissolved solids (TDS) (see glossary). Fresh water includes both potable and nonpotable, but treatable, water. Slightly saline water is defined as water with a chloride concentration between 25 and 1, mg/l or a TDS concentration between 5 and 3, mg/l. Small amounts of slightly saline ground water are either diluted with fresh water or treated by reverse osmosis to potable standards to be used for public supply. For other uses, slightly saline water is not treated. In this report, slightly saline water that has been treated is included in the reported quantities of fresh water. In reports published before 1987, slightly saline water was reported as saline. Some of the surface water use recorded in this report is saline water. Saline water is defined as water with a TDS concentration of more than 3, mg/l. Total water use in SJRWMD in 1992 was 3, mgd, of which 1, mgd was saline surface water and 1, mgd was fresh water (Table 3). These figures do not include reused wastewater (see appendix). 1

The largest use of saline surface water was for thermoelectric power generation 1,811.81, or 98 percent of the total saline surface water use in SJRWMD. In 1992, surface water accounted for a total of 2,38.9 mgd of water use (Table 3). This included water from both fresh and saline surface water sources. Twenty percent ( mgd) of the total water used in SJRWMD came from fresh surface water 12

22 1992 Water Use by Source sources. The remaining 8 percent of surface water came from saline sources. All of the saline water discussed in this report came from surface water sources. Fresh Water The county using the most fresh surface water ( mgd) was Indian River County (Table 3). Virtually all of this water (99 percent) was for agricultural irrigation. Volusia County used mgd of fresh surface water, 97 percent of which was for thermoelectric power generation. Water use in these two counties totaled mgd, or 64 percent of the total fresh surface water use in SJRWMD in The largest category of fresh surface water use was agricultural irrigation, which accounted for mgd (Table 4), or 6 percent (Figure 2) of the total fresh surface water use in SJRWMD. The second largest category of fresh surface water use was thermoelectric power generation, which accounted for mgd, or 28 percent of the total. Commercial/industrial water use accounted for mgd, or 8 percent of the total fresh surface water use in SJRWMD. Fresh surface water withdrawn for public supply accounted for mgd, or 3 percent of the total fresh surface water used. Fresh surface water withdrawn for recreational irrigation accounted for 5.41 mgd, or 1 percent of the total fresh surface water used. Saline Water Total saline water use in SJRWMD in 1992 was 1, mgd (Tables 3 and 4). Saline surface water is primarily used in SJRWMD for thermoelectric power generation or for commercial/ industrial plant operation. Thermoelectric power plants use large amounts of saline water for cooling purposes. This is recorded as a water use in this report even though nearly all of the cooling water is returned to its original source. 13

24 1992 Water Use by Source GROUND WATER Brevard County had the highest saline surface water use 1, mgd (Table 3), for thermoelectric power generation at two plants: Florida Power and Light ( mgd) Orlando Utilities Commission ( mgd) Duval County had the next highest saline surface water use mgd (Table 3), for power generation and commercial purposes at three plants: Jacksonville Electric Authority (488.5 mgd) Eastport Power Plant (41.44 mgd) Seminole Kraft Corporation (27.78 mgd) Indian River County had a saline surface water use of mgd at the Vero Beach Municipal Power Plant, and Nassau County had saline water use of.9 mgd at the ITT Rayonier paper mill. In 1992, ground water accounted for a total of 1,42.67 mgd of water use (Table 3), or 69 percent of the total freshwater use in SJRWMD. Generally, all ground water withdrawals are from freshwater sources. The counties in SJRWMD where the most ground water was used were Brevard, Duval, Indian River, and Orange (Table 3). Each of these counties used more than 1 mgd of ground water, for a total of mgd for the four counties, or 52 percent of the total ground water use in SJRWMD in The largest category of ground water use in 1992 in SJRWMD was public supply, which accounted for about 49.8 mgd (Table 4), or 39 percent of the total ground water use (Figure 2). The second largest category of ground water use was agricultural irrigation, accounting for mgd, or 33 percent of the total ground water use. Si. ]ohns River Water Management District 15

25 ANNUAL WATER USE SURVEY: 1992 Commercial/industrial water use accounted for mgd, or 11 percent of the total ground water use in SJRWMD in 1992; domestic self-supply for mgd, or 8 percent of the total; abandoned artesian wells for mgd, or 7 percent of the total; recreational irrigation for 12.3 mgd, or 1 percent of the total; and thermoelectric power generation for 6.18 mgd, or less than 1 percent of the total ground water use. 16

26 1992 Water Use by Category 1992 WATER USE BY CATEGORY PUBLIC SUPPLY In the following five categories of water use, most or all of the water used is fresh water: Domestic self-supply Agricultural irrigation Recreational irrigation Abandoned artesian wells In the following two categories of water use, both fresh and saline water are used: Thermoelectric power generation Commercial/industrial self-supply The public supply category consists of water supplied by utilities to homes and industries. Total water use from ground and surface sources for public supply in 1992 was mgd (Tables 4 and 5). All public supply water was fresh water, and most of the water supplied in 1992 (97 percent) was ground water (Table 4). Fresh surface water (14.83 mgd) was used for public supply in Brevard County. Eighty-nine percent of the ground water used in SJRWMD for public supply was withdrawn from the system; the remaining 11 percent was withdrawn from the intermediate and surficial aquifer systems (SJRWMD 1992a). The public supply category of ground water use accounted for 39 percent of the total ground water use in SJRWMD in 1992 (Figure 2). The figures in this report for fresh ground water use include a small amount of slightly saline ground water that was treated by reverse osmosis or blended with fresh water for use as potable water.

28 1992 Water Use by Category published before 1987, this slightly saline ground water was reported as saline water. Per Capita Water Use by County DOMESTIC SELF-SUPPLY The average per capita water use in SJRWMD in 1992, based on the population served by public supply, was 152 gallons per day (Table 5). This amount includes water used for residential as well as non-residential purposes. The counties with the largest populations in SJRWMD and consequently the counties with the largest public supply water use are Duval and Orange counties (Table 5 and Figure 3). Together, these counties represent about 41 percent of the SJRWMD public supply water use population. Water use for public supply in Duval (94.8 mgd) and Orange (93.15 mgd) counties was mgd, or 44 percent of the public supply water use in SJRWMD in Orange County is split between two water management districts; 34.8 mgd of public supply water use in Orange County was used in the South Florida Water Management District and therefore is not included in the totals in this report (see appendix). Also, some of the water withdrawn in Orange County (24.85 mgd) was for the City of Cocoa public supply system in Brevard County (Table 5). The City of Jacksonville (Duval County), which has the largest public supply utility in SJRWMD, supplied its 454,355 customers with mgd of fresh ground water in 1992 (see appendix). In 1992, an estimated 528,614 people used mgd of domestic self-supplied water (Table 5), or 8 percent of the total fresh ground water use in SJRWMD (Table 4). All of the domestic selfsupplied water was assumed to be ground water. 19

30 1992 Water Use by Category Marion County had the largest self-supplied population 92,987 people (Table 5). Orange County had the second largest, with 76,871 people, followed by Duval County with 56,2 people. COMMERCIAL/INDUSTRIAL SELF-SUPPLY The total self-supplied freshwater use in the commercial/ industrial category was mgd (Tables 4 and 6), or 1 percent of the total freshwater use in SJRWMD. Of this total, mgd was ground water and mgd was fresh surface water. In addition, mgd of saline water was used in this category. Most of the water used in this category supplied the pulp and paper industries in Putnam, Nassau, and Duval counties. In 1992, water use for pulp and paper production included mgd of fresh ground water, mgd of fresh surface water, and mgd of saline surface water (see appendix). The second largest water user in this category was the mining industry, which accounted for mgd of fresh water. Together, pulp and paper production and mining accounted for mgd of fresh water, or 81 percent of the commercial/ industrial self-supply freshwater use in SJRWMD. The largest amount of fresh water used for commercial/industrial self-supply (59.33 mgd) was in Putnam County (Table 6). Nassau (36.65 mgd) and Duval (31.17 mgd) counties also had significant amounts of freshwater use in this category. Of the total fresh water used for commercial/industrial self-supply in SJRWMD, 86 percent ( mgd) was in these three counties. AGRICULTURAL IRRIGATION Almost all of the water used for agricultural irrigation in SJRWMD was fresh water. A small but undetermined amount of moderately saline water (TDS > 1, but <3, mg/l) was used for agricultural irrigation in Indian River County. Total freshwater use for agricultural irrigation was estimated at 21

32 1992 Water Use by Category mgd, or 41 percent of the total freshwater use in SJRWMD in 1992 (Tables 4 and 7). Of this total, mgd, or 55 percent of the total water used for agriculture, was ground water. It was assumed that most ground water used for agricultural irrigation came from the Lower and Upper s. Water Use by Acreage and Crop Water Use by County An estimated 925,649 acres were farmed in SJRWMD in 1992, of which 375,247 acres were irrigated (see appendix). Of the total acreage irrigated, 263,477 acres were irrigated by flood systems, 58,477 acres by low pressure/low volume systems, and 53,293 acres by sprinkler systems. The total amount of irrigated acres decreased from 376,229 acres in 1991 a net decrease of 982 acres (Florence 1994). The largest water use for a single crop type was for citrus irrigation, which accounted for mgd, or 44 percent of the total agricultural water use in SJRWMD (see Figure 4 and appendix). Irrigation of improved pasture land accounted for mgd, or 21 percent of agricultural water use. The largest water use for agriculture occurred in Indian River County mgd of fresh water (Table 7), or 41 percent of the total water use for irrigation in SJRWMD. Most of this amount, 178. mgd, was fresh surface water. The second largest water use for agriculture was in Brevard County mgd, most of which was ground water. The water use in these two counties was mgd, or 55 percent of the total agricultural irrigation water use in SJRWMD in RECREATIONAL IRRIGATION Water used in the recreational irrigation category totaled mgd, or about 1 percent of the total fresh water used in SJRWMD (Table 8). Of this amount, 12.3 mgd was ground water. The largest water user for recreational irrigation occurred in Brevard County 2.82 mgd (see appendix).

36 1992 Water Use by Category THERMOELECTRIC POWER GENERATION Total water use for the 12 self-supplied power plants accounted for 1, mgd of saline surface water, mgd of fresh surface water, and 6.18 mgd of fresh ground water (Tables 4 and 9). The largest amount of saline water used for thermoelectric power generation was in Brevard County 1, mgd. The largest amount of freshwater use was in Volusia County mgd. ABANDONED ARTESIAN WELLS Water flowing from 585 abandoned artesian wells totaled an estimated mgd in SJRWMD (Table 1). The total known flow for 66 wells was 9.38 mgd. The estimated flow from 519 wells was mgd. All water was fresh ground water. The estimated flows were calculated by county, then summed for an SJRWMD total. The calculation is performed as follows: 1. Determine county average of known flow per well. 2. Multiply result (average known flow) by the estimated number of wells of unknown flow. 3. Combine the estimated unknown flow with the known flow for a county total. For counties with no wells of known flow, the per well average of all known flows in SJRWMD (.142 mgd) was used. SJRWMD began its Abandoned Artesian Well Plugging Program in As of 1992, 1,98 abandoned artesian wells had been identified, of which 777 wells had been plugged or repaired by SJRWMD, 618 had been plugged or repaired by the well owners, and 585 are still flowing (Steele 1993). As of September 1992, an estimated mgd of fresh water had been saved. 27

39 ANNUAL WATER USE SURVEY: 1992 TRENDS 1983 TO 1992 Total freshwater use increased by 16 percent over the period 1983 through The increase has been gradual and fairly consistent over the years, but the increase has occurred at a slower rate than population growth (Figure 5 and Table 11). The estimated population increased by 34 percent between 1983 and In general, the increase in total water use has been driven by increases in public supply water use offset by the decrease in agricultural irrigation water use. While the trend for the 1-year period has been one of gradual increase, annual fluctuations in water use occur in response to climatic conditions such as amount and distribution of rainfall (Figure 6). The arithmetic mean of total freshwater use for this 1-year period is 1, mgd. The normal yearly rainfall for the period is inches (SJRWMD 1994). The highest total water use occurred in 199, at 1, mgd, 9 percent above the 1-year mean. This year was the driest year of the period, with an average of 39 inches of rainfall (SJRWMD 1992b), or 22 percent below normal. The second highest amount of water use occurred in 1992, at 1, mgd, 7 percent above the 1-year mean. The year 1992 was one of the wettest years during the period, with an average rainfall of inches (NOAA 1993), or 13 percent above normal; much of the excess rainfall occurred during the first 3 months of the year. Rainfall during months of high water use tended to be below normal. The lowest amount of water use occurred in 1983, at 1,298.8 mgd, or 14 percent below the 1992 water use amount. Because rainfall in 1983 was 2 percent above normal 64 inches (Jenab et al. 1986) and population was 25 percent below that of 1992, the low water use can be assumed to be a factor of both population and rainfall. water use has increased steadily, with some annual fluctuations. Water use for this category was highest in 199 3

43 ANNUAL WATER USE SURVEY: TO 1992 ( mgd) and lowest in 1983 ( mgd). However, per capita use has remained consistently between 152 and 167 gallons per day. The arithmetic mean for this 1-year period is mgd; water use in 1992 was 9 percent above the mean. Domestic self-supply water use has remained relatively constant, with little fluctuation over the 1-year period. Water use for this category was highest in 1989 (9.24 mgd) and lowest in 1983 (8.99 mgd). The arithmetic mean for this 1-year period was mgd; in 1992, water use was less than 1 percent above the mean. Commercial/industrial self-supply water use has remained relatively constant, with little fluctuation over the 1-year period. Water use for this category was highest in 1985 ( mgd) and lowest in 199 ( mgd). The arithmetic mean for this 1-year period is mgd; in 1992, water use was 2 percent below the mean. Agricultural and recreational (turf grass) irrigation water use has decreased over the 1-year period, with the largest amount of annual fluctuation of all categories. Water use for this category was highest in 1992 (642.4 mgd) and lowest in 1991 ( mgd). The arithmetic mean for this 1-year period is mgd; in 1992, water use was 1 percent above the mean. Thermoelectric power generation and abandoned artesian well data are either incomplete or the methods for determining water use have varied. Therefore, comparisons of data for these categories would be inappropriate. From 1991 to 1992, total freshwater use in SJRWMD increased from 1,4.63 mgd to 1, mgd, or 8 percent. Fresh ground water use increased from 1,27.22 mgd to 1,42.67 mgd or 2 percent. Fresh surface water use increased from mgd to mgd, or 26 percent. Saline surface water use increased from 1,756.2 mgd to 1, mgd, or 5 percent (Florence 1994). 34

44 Trends SEASONAL TRENDS The following five categories of freshwater use increased from 1991 to 1992: freshwater use increased 3 percent, from mgd in 1991 to mgd in This increase in water use can be attributed to population growth during the year. Domestic self-supplied freshwater use increased less than 1 percent, from mgd in 1991 to mgd in Commercial/industrial freshwater use increased 3 percent, from mgd in 1991 to mgd in However, saline surface water withdrawals decreased 38 percent, from 45.9 mgd in 1991, to mgd in Agricultural and recreational irrigation freshwater use increased 14 percent, from mgd in 1991 to mgd in Abandoned artesian well flows increased 34 percent, from mgd in 1991 to mgd in One category of freshwater use decreased slightly from 1991 to 1992: Thermoelectric power generation freshwater use decreased 3 percent, from mgd in 1991 to mgd in However, saline surface water withdrawals increased 6 percent, from 1,71.93 mgd to 1, mgd in In 1992, total freshwater use was highest in May (Figure 7). Monthly trends in total water use follow the trends in agricultural water use, which depend on rainfall and growing season. March, April, and May tend to be both Florida's dry season and peak crop irrigation months, so irrigation demand usually increases during these months (Figure 8). Because July 1992 was 35

47 ANNUAL WATER USE SURVEY: 1992 Public Supply unseasonably dry, water use for the public supply and agricultural sectors increased significantly. Demand for residential lawn irrigation also tends to increase during these months, generating an increase in public supply water use. water use in SJRWMD in 1992 fluctuated from a low of mgd in January to a high of mgd in May (Figures 7 and 9). The seasonal fluctuations were greater than in 1991, despite the higher average annual rainfall. This effect is because much of the rainfall occurred during the cool season, when little outdoor residential use takes place. Typically, water use increases during the warm season (April through October), when outdoor residential use is at a high. Commercial/Industrial Self-Supply Commercial/industrial self-supply freshwater use in SJRWMD in 1992 varied 17 percent over the year from a low of mgd in October to a high of mgd in May (Figure 1). Agricultural and Recreational Irrigation Agricultural and recreational irrigation water use in SJRWMD in 1992 had a greater seasonal fluctuation than any other water use category from a low of mgd in February to a high of 1,94.69 mgd in May (Figure 11). These fluctuations are typical of agricultural water use and are inversely correlated to rainfall. Thermoelectric Power Generation Thermoelectric power generation freshwater use in SJRWMD in 1992 fluctuated from a low of 8.57 mgd in January to a high of mgd in August (Figure 12). Fluctuations in water use are related to power plant shutdowns for maintenance or increased power demands during periods of extremely high or low temperature. 38

52 Glossary GLOSSARY Abandoned Artesian Well. An artesian well, with or without a mechanism for controlling discharge, that allows water to flow continuously at the land surface or into other aquifers through internal flow because of improper well construction or condition. Also called wild flowing well, free-flowing well, and uncontrolled artesian well. Aquifer. A reservoir of ground water. In SJRWMD, there are three major aquifer systems: the Floridan, the intermediate, and the surficial. In this report, data for the intermediate and surficial aquifers are combined. Average Annual Water Use. The total quantity of water withdrawn during the year (in gallons) divided by 365 days except in a leap year. Reported in million gallons per day. Fresh Water. Water with a total dissolved solids concentration less than or equal to 1, mg/l. The freshwater category includes both potable and nonpotable water. Per Capita Use (gross). The average amount of water used per person during a standard time period, generally per day. per capita use refers to the amount of water used (withdrawn) for all uses by public supply water, divided by the population served. Potable Water. Water that meets the public drinking water quality standards for chloride and total dissolved solids set by the Department of Environmental Protection. Potable water is considered safe for human consumption and is often referred to as drinking water. In Florida, chloride and total dissolved solids concentrations in potable water must be less than or equal to 25 mg/l and 5 mg/l, respectively. 43

53 ANNUAL WATER USE SURVEY: 1992 Reverse Osmosis. A process of desalination that removes chlorides or other dissolved solids from saline water to make it potable. Saline Water. Water with a chloride concentration greater than 1, mg/l or a total dissolved solids concentration greater than 3, mg/l. Self-Supplied Water. Water withdrawn from a ground or surface water source by a user and not obtained from a public supply. Slightly Saline Water. Water with a chloride concentration between 25 and 1, mg/l or a total dissolved solids concentration between 5 and 3, mg/l. This water is nonpotable, but treatable. Slightly saline water is either diluted with fresh water or treated by reverse osmosis to potable standards for public supply. For other uses, this water is generally not treated. In this report, treated or diluted slightly saline water is included in the reported quantities of fresh water. Water Use. The quantity of water used and the way in which the water is used in SJRWMD. In most cases, water use equals withdrawals; however, in some cases, water is withdrawn in one county for use in another county. In the latter case, notations are made; otherwise, water use equals withdrawal. Water Withdrawals. The amount of water withdrawn from a source (ground or surface, fresh or saline). Withdrawals are equivalent to intake, water diversion, or pumpage, terms commonly associated with industrial, agricultural irrigation, and public supply use, respectively. Water withdrawals are considered water use for this report. 44

58 ^ Appendix APPENDIX: 1992 WATER USE BY COUNTY This appendix presents the detailed water use data from which this report is constructed. SJRWMD totals are first presented for population, land area (University of Florida 1993b), water withdrawals by category, agricultural acreage, and water use by crop. Then, for each county, tables present population and land area totals, with water withdrawals by category; the reported water use of large, individual water users; and agricultural acreage and water use by crop. On the county water user tables, the withdrawal source is fresh water unless designated (by footnote) as saline water. Monthly freshwater use is graphed for public supply water use except for counties that have only a small area in SJRWMD (such as Okeechobee and Osceola), where the numbers are very small. Some totals may not equal 1 percent because of rounding. 49
