A for QA/QC, details, methods, procedures, abbreviations, and acronyms used in <br /> sampling and analysis <br /> Following depth to water measurements, WEGE and PWP personnel used a truck <br /> mounted vacuum lift pump and dedicated one inch diameter PVC tubing to purge each <br /> well of three volumes of water <br /> After purging, the wells were allowed to recover to at least 80% of their original well <br /> volumes A groundwater sample was then collected from each well with a polyethylene <br /> bailer and decanted with no headspace into two 40 ml VOA vials containing 0 5 ml HCL <br /> acid as a preservative <br /> The samples were delivered with accompanying chain of custody documentation to KIFF <br /> Analytical LLC (DHS certified #2236) analyzed the water samples from each monitor <br /> well for concentrations of TPH-G, BTEX and MtBE using EPA method 8260B, see <br /> Appendix C - Laboratory Report <br /> DISPOSITION OF WASTEWATER <br /> Groundwater purged during the May 22, August 12, and November 21, 2002 sampling of <br /> the monitor wells was temporarily contained on-site in labeled 55 gallon DOT approved <br /> drums <br /> RESULTS OF DUARTERLY GROUNDWATER MONITORING <br /> GROUNDWATER GRADIENT AND FLOW DIRECTION <br /> A-ZONE- 1876 AND 1856 CouNTRYCLuB BOULEVARD <br /> Figure 4A uses the new survey elevations supplied by Kjeldsen, Sinnock& Keudeck, Inc <br /> survey dated May 1, 2001 and the well locations and survey elevations associated with <br /> Country Club Food and Fuel, supplied by AGE Figure 4A shows the groundwater <br /> elevation gradient and flow direction determined from depth to water measurements at <br /> the five on-site monitor wells, the newly installed A Zone wells and the wells associated <br /> with Country Club Food and Fuel, on November 21, 2002 The groundwater elevation <br /> has decreased between 0 89 to 102 feet since the 3rd quarterly 2002 monitoring The <br /> current groundwater gradient shows an irregular contour flowing to the north northwest at <br /> a gradient of 0 0016 ft/linear ft(MWS to MW6A) <br /> 5 QM 4th 2002 <br />
