GENERAL PROJECT DESCRIPTION The Northwest Florida Water Management District (DISTRICT) is seeking bids from qualified well drilling CONTRACTOR(s) for the construction of up to four (4) Upper Floridan aquifer (UFA) long-term monitor wells, up to two (2) UFA aquifer performance test (APT) monitor wells and up to two (2) Surficial Aquifer System (SAS) monitor wells. The wells will be constructed across four sites in coastal Santa Rosa, Okaloosa, and Walton Counties as shown on Figure 1. Wellhead components and equipment will be provided under the construction contract. It is anticipated that the proposed work will take approximately ten months to complete. Depending on the bids received and budgetary constraints, the work may be divided over two fiscal years. The four (4) long-term monitor wells and the two (2) APT monitor wells will be completed in the UFA with the intent of spanning the entire thickness of the formation. The two (2) SAS monitor wells will be completed into the undifferentiated sands and clays containing the surficial aquifer. Expected casing seat and open-hole completion depths will range greatly from site to site for the UFA monitor wells. The anticipated casing and well depths are listed in Section 1007, Well Specifications. Actual casing and open-hole or screen-interval depths will vary at each well site subject to the specific subsurface conditions encountered. The DISTRICT plans to work with a separately contracted GEOLOGIST to assist in providing well construction oversight. The GEOLOGIST, in consultation with the DISTRICT, will provide the CONTRACTOR with depths for setting casing and open-hole/screened interval completion after evaluating hydrogeologic data collected during drilling and prior to those construction stages. The work scope described in these Technical Specifications involves the construction of up to eight (8) monitor wells. Representative lithologic and groundwater samples will be collected during well construction, and geophysical logging will be performed at key stages of the monitor well construction. The CONTRACTOR will also perform stepdrawdown tests on up to four (4) of the UFA long-term monitor wells. It should be noted that based on information obtained during construction and testing of the above described wells and pending budgetary constraints, the DISTRICT may opt not to perform any portion of the described work. A mandatory pre-bid conference will be held to address questions from potential bidders and discuss details of the project. Site maps are provided in this Bid Package and each bidder is urged to visit the sites in advance of the pre-bid conference to familiarize themselves with the sites and bring forward any questions or concerns.

39 SECTION 1007 WELL SPECIFICATIONS This Section describes the various components of the construction of the long-term and APT monitor wells, and is subdivided into the following main components: Part 1 Well Construction Sequence Part 2 Conditions and Hazards Part 3 Mobilization, Site Preparation, and Demobilization Part 4 Drilling Requirements Part 5 Data Acquisition Part 6 Material Specifications Part 7 Well Completion PART 1 - WELL CONSTRUCTION SEQUENCE The anticipated well casing and open-hole depths listed in the following well construction sequence are approximate. Actual depths may vary depending on the specific subsurface conditions encountered during well construction. The CONTRACTOR should also be aware that the well testing procedures described below may be changed in order of performance, or deleted, and additional work may be added at the discretion of the DISTRICT. In summary, the new wells to be constructed as part of this Project are anticipated to include the following: Well ID Well Type Aquifer Diameter (in) Cased Depth (ft) Total Depth (ft) A-2 Long-Term Monitor Well UFAS A-2a APT Monitor Well UFAS A-3 Long-Term Monitor Well UFAS A-3b SAS Monitor Well SAS A-4 Long-Term Monitor Well UFAS A-4a APT Monitor Well UFAS A-4b SAS Monitor Well SAS B-2 Long-Term Monitor Well UFAS 6 1,100 1,200 ITB 16B-007- Deep Exploratory Testing and Monitor Well Construction in the Upper Floridan Aquifer 16 Attachment B Technical Specifications

40 The construction sequence will be determined by the DISTRICT and GEOLOGIST so that hydrogeologic data can be obtained that will be used to help determine casing and open-hole depths for the wells to be drilled. Unless otherwise specified, the construction of the Long-term Monitor Well shall be followed by construction of the APT monitor well(s), if any. Subsequently, at Sites A-3 and A-4, the SAS monitor well shall be drilled after the Long-term Monitor Well and APT monitor well have been completed. The UFA Long-term and APT monitor wells will also require surface casing as part of their construction. It will be necessary to over-drill the pilot hole for the Long-term Monitor Wells to ensure the entire thickness of the UFA has been penetrated as determined by the GEOLOGIST. Pilot holes may be partially back-plugged before final completion depth of the open hole is determined by the GEOLOGIST. The CONTRACTOR shall determine at each site a suitable source water supply for well construction and drilling purposes. With DISTRICT approval, the CONTRACTOR may drill a make-up water well at site A-4 in lieu of using a source such as a hydrant. This site does not have an existing water source in proximity. The CONTRACTOR shall obtain a meter from the local municipality to monitor all water used from existing sources such as hydrants. With DISTRICT approval and availability of adequate oversite, the CONTRACTOR may be allowed to perform work at more than one site at a time provided the CONTRACTOR has sufficient equipment and personnel to successfully conduct approved work. Performance of all Items in this Bid Package by the CONTRACTOR at the request of the DISTRICT shall not be considered a cause for extending the Construction Schedule. Unless otherwise directed by the DISTIRCT, the sequence of site activities will proceed as described below.

51 PART 2 - CONDITIONS AND HAZARDS A. GENERAL The information provided regarding subsurface conditions and potential drilling hazards is intended to assist the CONTRACTOR in preparing the Bid. The DISTRICT or GEOLOGIST does not guarantee its accuracy or that it is necessarily indicative of conditions to be encountered in drilling the wells. The CONTRACTOR shall satisfy himself regarding all local conditions affecting the work by personal investigation and neither the information on local geology, nor that derived from maps or plans provided by the DISTRICT or his agents shall act to relieve the CONTRACTOR of any responsibility hereunder or from fulfilling any and all terms and requirements of the Technical Specifications. The CONTRACTOR should be aware of possible difficult drilling conditions and problems that may be encountered during the construction and testing of the wells. Typical examples include, but are not limited to, lost circulation zones, pressurized zones, and potential intervals of swelling clay and caving sand. The production casings shall seal off all formations encountered along their entire length and open borehole completions shall be free of obstructions. The drilling of straight, gauge holes and setting of all casings to specified depths is a priority requirement of these Technical Specifications. Borehole straightness, which will permit casings to be set at specified depths and facilitate achievement of proper cement seals, shall not be sacrificed for drilling speed. These and other pertinent factors shall be taken into consideration by the CONTRACTOR in planning and executing the Project. B. ANTICIPATED GEOLOGY AND POTENTIAL HAZARDS It is anticipated that the boreholes will encounter undifferentiated sand deposits of the surficial aquifer system in the upper approximately 60 feet bls. The surficial sands are expected to be underlain by the siliciclastic clayey sand and gravel deposits of the Citronelle Formation and transition into the clay, sandy-clays and shelly formations of the Intermediate System. Varying across the Project sites from east to west, the top of the UFA is anticipated at depths ranging from feet bls. The UFA in the project area is anticipated to include the Bruce Creek Limestone, and the Chickasawhay/Suwannee Limestone reaching depths of approximately feet bls from east to west. Unconsolidated sands and swelling clays may be present in the intervals to be drilled for this project. The CONTRACTOR should be prepared for such eventualities. C. HYDROLOGIC CONSIDERATIONS Regional hydrogeologic data and information obtained during site visits to the existing monitor wells indicate that potentiometric heads in the upper part of the Floridan aquifer are generally below land surface in the project area. However, it is possible that artesian heads above land surface may be encountered at Site A-4. It shall be the CONTRACTOR S responsibility to control all flow and discharge of water produced during all stages of well construction, development, and testing. This shall be ITB 16B-007- Deep Exploratory Testing and Monitor Well Construction in the Upper Floridan Aquifer 28 Attachment B Technical Specifications

52 implemented using drilling mud only as a weight material to suppress flow during mudrotary drilling and through the use of a flow preventer or other approved flow control devise during reverse-air drilling. The use of salt or others brines as a weight material shall not be allowed without prior approval of the GEOLOGIST and the DISTRICT. The flow preventer such as a Grant type rotating head rubber or other drill through rubber shall be a commercially-available, single annular type, or approved equivalent. Manufacturer s specifications pertaining to the type of preventer proposed for use by the CONTRACTOR shall be provided to the GEOLOGIST for review and approval. The wellhead shall be sealed at all times when no work is being conducted. PART 3 MOBILIZATION, SITE PREPARATION AND DEMOBILIZATION A. MOBILIZATION The CONTRACTOR shall set-up equipment necessary to achieve the quality of workmanship required by these Technical Specifications and to complete the Project on schedule. B. SITE PREPARATION 1. The District will be responsible for improving road access conditions on District property. Within the limits of the work areas, the CONTRACTOR may trim limbs and clear scrub brush only as directed and to the extent necessary to facilitate the setup and safe operation of the drilling equipment. All material and debris resulting from clearing and trimming operations shall be disposed in a manner approved by the GEOLOGIST. It shall be the responsibility of the CONTRACTOR to obtain any permits that are required for these procedures. 2. As needed, land surfaces shall be filled and graded such that runoff is directed away from the above ground well head apparatuses. 3. As needed, the CONTRACTOR shall maintain an all-weather temporary access to the wells and construction staging areas. Any turf and/or other plantings that are destroyed by the CONTRACTOR shall be replaced with like-kind. 4. The CONTRACTOR shall include the cost of this maintenance and sod and or plantings replacement in the lump sum pay item for Mobilization on the Bid Schedule Form. C. DEMOBILIZATION AND SITE RESTORATION At the completion of the Project, the CONTRACTOR shall remove all excess materials and equipment and leave the sites in a condition acceptable to the GEOLOGIST and the DISTRICT. Project areas outside of the permanent well site easement shall be restored to original contours. Drilling areas shall be clean and free of debris, holes, and/or piles of dirt, brush or other natural and synthetic materials. All drilling fluids and drill cuttings shall be removed from the work sites. ITB 16B-007- Deep Exploratory Testing and Monitor Well Construction in the Upper Floridan Aquifer 29 Attachment B Technical Specifications

53 All areas disturbed by construction shall be restored to a condition at least equal to the preconstruction condition including, but not limited to, all landscaping, driveways, roads, fences, and other improvements. Any formerly existing sod or landscape vegetation shall be replaced with vegetation equal to that destroyed or damaged. The GEOLOGIST shall maintain a photographic record of pre and post-construction conditions at the work sites to substantiate any claims for pre-existing damage and submit photographic records as a part of the completion report for each well as previously discussed in Section Reports. PART 4 - DRILLING REQUIREMENTS A. EQUIPMENT REQUIREMENTS 1. The CONTRACTOR shall provide equipment that is in good working order. The DISTRICT will not approve or pay for standby time due to delays resulting from the failure of poorly maintained equipment. The DISTRICT and GEOLOGIST shall reserve the right to inspect the equipment of bidding CONTRACTOR to assure qualifications. The CONTRACTOR shall use his own drilling equipment having the capabilities necessary to do the described work. Any unnecessary delays or work stoppages due to equipment failure shall not be considered a valid reason for extending the Construction Schedule. The CONTRACTOR shall be held responsible and payment may be withheld for damages to a well due to any cause of negligence, faulty operation, or equipment failure. 2. The CONTRACTOR shall provide and operate equipment capable of handling the largest load that will be placed upon the rigs' drilling and supporting equipment. If conditions develop in the field that prove the rig and supporting equipment supplied by the CONTRACTOR are incapable of completing a well, the CONTRACTOR will be required, at his own expense, to provide equipment with the necessary capacity. B. WATER SUPPLY Only potable water approved by the DISTRICT shall be used for makeup of drilling fluid and grout preparation. It is the CONTRACTOR S responsibility to coordinate with local utilities and supply all necessary water to the sites to complete the project. As part of the bidding process and for inclusion in the cost estimate the CONTRACTOR should evaluate the options for supplying water to each site. For the drill sites located in close proximity to a fire hydrant, The CONTRACTOR may make arrangements with the local utility to obtain water from the hydrant. The CONTRACTOR shall meter all potable water used and the cost of purchasing water should be included in the unit cost to drill. For those sites without a potable supply in proximity (particularly Site A-4) it shall be the CONTRACTOR s responsibility to provide a means of delivering the water to the work sites or, with DISTRICT approval, construct a temporary supply well at the CONTRACTOR s expense. ITB 16B-007- Deep Exploratory Testing and Monitor Well Construction in the Upper Floridan Aquifer 30 Attachment B Technical Specifications

54 C. DRILLING METHODS Surface casings can be installed by one of various methods selected by the CONTRACTOR and approved by the DISTRICT. Pilot hole drilling and reaming shall be conducted by either the mud-rotary or the reverse-air method, as specified in Part 1 of this Section. Deviation surveys of either the pilot or reamed borehole shall be conducted every 60 feet if requested by the GEOLOGIST. The reverse-air method shall be used for all open hole drilling, except where otherwise specified and in limited cases where formation yields are inadequate and an external source of potable water is required to circulate cuttings. Clear water circulation shall be used to purge casings of drilling mud and drill-out cement plugs following casing installation. The CONTRACTOR shall ensure that an adequate source of potable water or other external water supply approved by the DISTRICT is introduced into the well until sufficient formation circulation has been established in order to avoid exceeding the hydraulic collapse pressure of the casing. During reaming operations, the CONTRACTOR shall incorporate a bottom hole assembly consisting of the use of a lead bit and a staged drilling assembly with stabilizer to facilitate pilot hole tracking and plumb borehole. Drilling mud shall be conditioned using a shale shaker and de-sanders, or other approved equipment before being recirculated into the borehole. D. DRILLING FLUIDS Fluid for mud-rotary circulation shall be a mixture of potable water and high-grade bentonite unless other types of drilling fluid or fluid additives have been approved in advance by the GEOLOGIST and the DISTRICT. All drilling additives must be approved for use in public supply wells by NSF. Proper makeup and conditioning of drilling mud should be applied to maintain a fluid density ranging from 8.6 to 9.0 lbs/gallon under normal drilling conditions. The borehole should be prepared for casing installation by continuing fluid circulation until cuttings have been completely removed from the borehole and the drilling fluid is uniform. Excessive mud thickening should be corrected prior to casing installation. Care should be taken to prevent swabbing due to high mud viscosity or high gel strength when the drill string is tripped in or out of the hole. The CONTRACTOR shall provide a mud balance and weigh at least three samples of the conditioned drilling fluid during final circulation over two hours before installing production casing strings. The CONTRACTOR shall also measure Marsh funnel viscosity, which should be below 40 seconds, when circulating drilling fluid prior to cementing. Sample weight, viscosity, and collection time shall be recorded in the CONTRACTOR's Daily Log. E. LOST CIRCULATION Lost circulation conditions may be encountered while drilling with mud. The use of lost circulation materials shall be restricted to those materials approved by FDEP and NSF, ITB 16B-007- Deep Exploratory Testing and Monitor Well Construction in the Upper Floridan Aquifer 31 Attachment B Technical Specifications

55 with prior approval from the DISTRICT. Drilling without circulation is not acceptable without consent of the GEOLOGIST. F. CUTTINGS, DRILLING FLUID, AND FORMATION WATER DISPOSAL 1. Drill cuttings and fluids from mud-rotary drilling shall be removed from the construction sites and disposed at an approved location. The CONTRACTOR shall furnish to the GEOLOGIST, prior to beginning construction, the name and location of the disposal site along with documentation that the site has been approved by the appropriate regulatory agencies. Fluids displaced from the borehole during cementing operations shall be considered excess drilling fluid and shall also be disposed in an approved manner. All disposal costs shall be included in the price of the well. 2. Formation fluids from reverse-air drilling, well development and well testing shall be treated to remove suspended solids (e.g. settling tank, silt fence, hay bales, etc.) and then discharged, with DISTRICT approval, to a local storm water catch basin or on-site detention pond. In all cases, a discharge point manifold arrangement shall be emplaced in order to eliminate erosion or any other impact to soil, vegetation, wildlife or create any hazard. For purpose of the Bid, the CONTRACTOR should assume that the discharge point will be located up to 500 feet from the drill site. G. CEMENTING PROCEDURES The CONTRACTOR will prepare and submit a site-specific grouting plan that describes the approach to cementing the surface and final well casings. The grout plan will be review and approved by the DISTRICT prior to proceeding. The plan will indicate whether grouting will be performed in one single lift or in stages. Adequate details and calculations shall be included to support the grouting method and the final integrity of the well casings. Minimum set times for cement prior to drilling out the casing shall also be proposed. In particular, unless an agreeable alternative is proposed and approved, the cementing of the final well casing shall be accomplished in stages by means of a collarless tremie pipe with the exception of the first stage cement, which shall be pressure grouted. Before each cementing stage, the CONTRACTOR shall tag the top of the cement emplaced in the previous stage with a collarless tremie pipe and recondition the mud to assure proper mud displacement by the cement. Grouting shall be undertaken using ASTM Type II neat Portland cement. The neat cement may have up to 5% bentonite added. The first stage of cementing shall utilize the pressure grouting method to establish a cement seal at the base of the casing. Subsequent stages shall be performed using a collarless tremie pipe. The CONTRACTOR shall maintain the bottom of the tremie pipe within the placed cement at all times during grouting until cement stage is complete and cement in tremie tubing has been displaced. The CONTRACTOR shall take appropriate measures to avoid exceeding the allowable collapse and burst pressures of the casing during installation and cementation. ITB 16B-007- Deep Exploratory Testing and Monitor Well Construction in the Upper Floridan Aquifer 32 Attachment B Technical Specifications

56 The CONTRACTOR shall calculate total cement requirements, determine the number of stages and the volume of grout introduced during each stage, and carefully monitor work progress. The calculations shall be included in the site-specific grouting plan. Maximum cement stages shall not exceed 100 linear feet without prior approval of the GEOLOGIST. The CONTRACTOR shall pump only the theoretical amount of cement for each stage unless prior approval of the GEOLOGIST. The CONTRACTOR should exercise his own professional judgment to determine if cement stages less than the maximum values listed above should be applied. When casing is being set and cemented in place, the CONTRACTOR shall take appropriate measures to avoid exceeding the allowable collapse and burst pressures of the casing, taking into account the heat of hydration produced during grout setup. Procedures for each stage of cementing shall be continuous. If loss of circulation or no return of drilling fluid is encountered, the GEOLOGIST shall be notified immediately of what remedial measures are underway to re-establish circulation and complete the cementing program according to the Technical Specifications. It may be necessary to use gravel in sections of the borehole that exhibit high transmissivity to reduce the loss of cement to the formation. The use of gravel shall be coordinated with and approved by the DISTRICT before use. Gravel shall be paid at the same cost (per liner foot of casing installation) of cementing. Emplacement of gravel shall either be completed via gravel pump or gravity feed depending on depth, as required by the GEOLOGIST. The CONTRACTOR shall tag the top of the gravel emplaced in the previous stage with a collarless tremie pipe before any additional cement stage is performed. It may be necessary to plug back a portion of a borehole with cement. In such cases, cementing shall be done through a collarless tremie pipe positioned slightly above the bottom of the borehole or top of the previous cement stage. The CONTRACTOR shall determine the volume of cement that shall be used in each grout stage and the number of stages required to back-plug only the portion of the borehole specified by the GEOLOGIST. H. WELL DEVELOPMENT The CONTRACTOR shall utilize a combination of reverse-air circulation and/or high rate pumping to develop the wells until the discharge water is free of sediments and turbidity as determined by the GEOLOGIST. The procedures used by the CONTRACTOR to develop the wells shall be as follows: 1. Initial development shall be by reverse-air circulation. This shall be implemented by tripping tubing or drill bit in the well and varying the intake depth throughout the entire open-hole section while maintaining circulation. Prior to removing tubing or the drill string, the CONTRACTOR shall ensure that no cuttings or debris remain in the bottom of the borehole, and 2. The CONTRACTOR shall complete development by furnishing and developing the well with an electric submersible or vertical turbine test pump capable of producing a withdrawal rate of 250 to 500 gallons per minute (gpm). The well ITB 16B-007- Deep Exploratory Testing and Monitor Well Construction in the Upper Floridan Aquifer 33 Attachment B Technical Specifications

57 shall be repeatedly surged during this process. A calibrated flow meter or an orifice plate shall be installed on the discharge pipe to measure the pumping rate. While the test production wells are being developing with the test pump, the CONTRACTOR shall furnish a centrifugal sand sampler, or other approved method of quantifying sand content in the part per million range, a calibrated turbidity meter, and a silt density index (SDI) kit which the CONTRACTOR shall install on the discharge pipe. The CONTRACTOR shall periodically sample the pump discharge for turbidity, sand content, and SDI to determine when adequate development has been achieved to the satisfaction of the GEOLOGIST. The CONTRACTOR shall have mechanism set up for GEOLOGIST to measure the pumping water level and obtain water quality samples at any time during development and testing. These results shall be recorded in the CONTRACTOR s Daily Log. I. WELLHEAD SECURITY At all times during the progress of the Project, the CONTRACTOR shall use reasonable precautions to prevent either tampering with the well or the entrance of foreign material into the wells/boreholes. Site fencing shall be erected, as needed, to restrict access to the wellhead and work area. When flowing conditions may be encountered, the well shall be contained at all times to prevent uncontrolled flow. The well shall be sealed at the end of the work day to prevent any potential for entrance of wildlife or other biological entrance. J. WELL FLOW SUPPRESSION Control flow as necessary during all stages of well construction, development and testing. Implement using drilling mud only as a weight material to suppress flow during mud-rotary drilling and through the use of a blowout preventer or other flow control device during reverse-air drilling. The use of salt or other brines as a weight material will not be allowed without prior approval of the GEOLOGIST and DISTRICT. Utilize a blowout preventer of a commercially available, single annular type, or approved equivalent. Seal the wellhead at times when no work is being conducted. PART 5 - DATA ACQUISITION A. FORMATION SAMPLES One set of formation samples (drill cuttings) shall be collected at 10-foot intervals and at every formation change during the construction of each Long-term Monitoring Well. Samples shall be bagged at intervals of no greater than 10 feet in depth. Bagging over shorter intervals may be specified by the GEOLOGIST in cases where significant lithologic changes occur. Samples shall be preserved in cloth sample sacks furnished by the CONTRACTOR and plainly marked with the well identification number and depth below land surface from which they were collected. The CONTRACTOR shall obtain the samples, provide acceptable facilities for storage of samples while they remain on site, and deliver them to the GEOLOGIST. Samples shall be of such volume that they can later be divided by the GEOLOGIST into three sets (GEOLOGIST, DISTRICT, and FGS). ITB 16B-007- Deep Exploratory Testing and Monitor Well Construction in the Upper Floridan Aquifer 34 Attachment B Technical Specifications

58 B. REVERSE-AIR CIRCULATION WATER SAMPLING Prior to every rod change during reverse-air drilling (maximum interval 30 feet), the CONTRACTOR shall collect a clear water sample from the drill stem discharge after cuttings have been flushed from the well. Samples will be analyzed in the field by the GEOLOGIST for specific conductance, temperature, ph and chloride ion concentrations.
