62-701.500(2)(1) <br />WATER QUALITY MONITORING <br />Current groundwater quality sampling consists of semi-annual sampling at 36 onsite <br />wells. These wells include wells installed as monitoring and detection wells during <br />October and November 1995. There are 12 shallow wells (less than 20 feet deep), 12 <br />intermediate wells (30 feet to 40 feet depth), and 12 deep wells (50 feet to 80 feet depth). <br />Semi-annual sampling parameters include total dissolved solids, turbidity, total organic <br />carbon, ammonia -nitrogen, nitrates, organic nitrogen, pH, chlorides, sulfur, specific <br />conductive, bicarbonate ion, color, and water level. In addition, samples are analyzed <br />for magnesium, potassium, iron, manganese, zinc, and sodium. Data is submitted on <br />standard storet code sheets to the FDEP semi-annually in accordance with the approved <br />November 1994 comprehensive water quality monitoring plan. A bi-annual report is <br />being prepared to cover the last two years. An annual groundwater and surface water <br />quality report is prepared and submitted to FDEP. The location of monitoring wells <br />and surface water sampling points is shown on Figure 3-3 of the infill segment permit <br />application. <br />Field sampling and laboratory analysis are performed by an EPA -and -HRS certified <br />analytical lab, Envirometrics, Inc. of Vero Beach, Florida. Envirometrics, Inc. has an <br />approved field sampling quality assurance plan and an approved comprehensive <br />laboratory analysis quality assurance plan for groundwater, surface water, and leachate. <br />Surface water sampling is conducted quarterly at four locations at or near the discharge <br />points from the borrow pond and the stormwater pond. The locations are at the <br />discharge point from the sedimentation ponds, on the C-6 canal, an upstream location <br />on the C-6 canal, and a downstream location approximately 1,100 feet east of the <br />sedimentation pond outfall. The fourth location is at the discharge weir for the <br />stormwater pond conveyance ditch. This location has been dry (no discharge) during <br />v <br />F-11 <br />.4• •' j:.... <br />
