COLLECTION AND CERTIFIED ANALYSIS OF GROUNDWATER SAMPLES <br /> WEGE and Pittman Well Purging (PWP) personnel collected quarterly groundwater <br /> samples from the eleven monitor wells at the site on August 7, 2003 See Appendix A <br /> for QA/QC, details, methods, procedures, abbreviations, and acronyms used in sampling <br /> j 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) The laboratory analyzed the water samples from <br /> each monitor well for concentrations of TPH-G, BTEX and MtBE using EPA method <br /> 8260B, see Appendix C -Laboratory Report <br /> DISPOSITION OF WASTEWATER <br /> Groundwater purged during the May 22, 2003 sampling of the monitor wells was <br /> processed through 4, in series, water carbon units, no discharge occurred from the e <br /> carbon Groundwater purged during the August 7, 2003 sampling of the monitor wells <br /> was processed through the 4, in serves, water carbon units 40 gallons of treated water <br /> was discharged from the 4h carbon unit into a 55 gallon drum This water was sampled <br /> and temporarily contained on-site to the 55 gallon DOT approved drum Sample results <br /> showed this water could be discharged to the sanitary sewer and was discharged on <br /> August 28, 2003, see August 2003 Sewer Discharge Report, Appendix D <br /> RESULTS OF QUARTERLY GROUNDWATER MONITORING <br /> GROUNDWATER GPADIENT AND FLOW DIRECTION <br /> i <br /> A-ZONE - 1876 AND 1856 COUNTRY CLUB Bor�'YARD <br /> Figure 4A uses the new survey elevations supplied by Kjeldsen, Sinnock &Keudeck, Inc <br /> survey dated May 1, 2001 Figure 4A shows the groundwater elevation gradient and flow <br /> direction determined from depth to water measurements at the four on-site monitor wells <br /> 5 QM 3"d 2003 <br />
