1 <br /> 1 <br /> Following the groundwater level measurements, each of the wells was purged and sampled The <br /> wells were purged using a pump and dedicated disposable tubing, until at least three well casing <br /> volumes were extracted and/or after groundwater temperature, pH and electrical conductivity <br /> values had stabilized Following well purging and recharge, groundwater was sampled from the <br /> wells using dedicated disposable bailers and laboratory-supplied containers Each sample <br /> container was labeled, packaged in an iced cooler and transported with chain-of-custody <br /> rdocumentation to Kiff for analysis Kiff analyzed each of the groundwater samples for TPH-as- <br /> gasoline, BTEX, MTBE, 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 stockpiled on-site using a base <br /> and cover of plastic sheeting Based on the absence of gasoline constituent compounds in soil <br /> sample analyses performed during this investigation, the soil stockpile was uncovered and spread <br /> out at the site <br /> Wastewater from equipment nnsate and well purging was contained in 55-gallon drums, and <br /> stored temporarily on-site pending waste profiling and proper disposition Based on the absence <br /> of gasoline constituent compounds in soil and groundwater sample analyses performed during <br /> this investigation, the wastewater was discharged on-site <br /> 2.3 Domestic Well Sampling and Analysis <br /> On December 17, 2001, Ramage Environmental also collected a groundwater sample from the <br /> on-site water well for laboratory analysis Prior to sampling, the well was purged until the well <br />' pump was activated The groundwater samples were collected from the wellhead sampling port <br /> into laboratory-supplied containers, which were labeled, packaged in an iced cooler and <br /> transported with chain-of-custody documentation to Kiff Kiff analyzed the water well sample for <br />' TPH-as-gasoline, BTEX, MTBE, DIPE, ETBE, TAME, TBA and 1,2-DCA by EPA Method 8260B <br /> 1 <br /> 1 <br /> 13 <br />
