1 <br /> Following the groundwater level measurements, MW-2 and MW-3 were purged and sampled <br /> Due to the presence of free product, MW-1 was not sampled The wells were purged using a <br /> pump and dedicated disposable tubing, until at least three well casing volumes were extracted, <br /> and/or after groundwater temperature, pH and electrical conductivity values had stabilized <br /> Fallowing well purging and recharge, groundwater was sampled from the wells using dedicated <br /> disposable bailers and laboratory-suppled containers Each sample container was labeled, <br /> packaged in an iced cooler and transported with chain-of-custody documentation to Kiff for <br /> analysis Kiff analyzed each of the groundwater samples for TPH-as-gasoline, BTEX, MTBE, <br /> DIPE, ETBE, TAME, TBA, and 1,2-DCA by EPA Method 8260B <br />' 2 2 4 Waste Storage and Disposal <br /> Waste soil cuttings generated during the drilling operations were contained in three 55-gallon <br /> drums for temporary on-site storage, pending waste profiling and disposition On November 29, <br /> 2001, Ramage Environmental collected a soil sample from each of the three drums for laboratory <br /> composite and analysis Kill analyzed the composite soil sample for TPH-as-gasoline, BTEX, and <br /> MTBE by EPA Method 826013, and for total lead by EPA Method 6010 The composite soil <br /> sample did not contain detectable concentrations of gasoline compounds or hazardous <br /> concentrations of lead As such, the waste sod is currently pending on-site disposition The <br /> laboratory report is included in Appendix D <br /> Wastewater from equipment rinsate and well purging was contained in 55-gallon drums <br /> Currently, the wastewater is pending accumulation and proper disposal <br /> 2.3 Municipal Irrigation Well Sampling and Analysis <br />' On December 28, 2001, Ramage Environmental collected a groundwater sample from the off-site <br /> municipal irrigation well During the winter months, the well is inactive, and the pump could not be <br /> activated prior to sampling Instead, a sample was collected directly from the pressure tank into <br /> laboratory-supplied containers, which were labeled, packaged in an iced cooler and transported <br /> with chain-of-custody documentation to Kiff Kiff analyzed the irrigation well sample for TPH-as- <br /> gasoline, BTEX, MTBE, DIPE, ETBE, TAME, TBA and 1,2-DCA by EPA Method 8260B <br /> 1 <br /> 9 <br />
