2 2 3 Groundwater Monitoring, Samplinq and Analysis <br /> On September 7, 2000, groundwater from the three newly-installed wells was monitored and <br /> sampled Upon arrival at the site, each of the wellheads was inspected, unlocked and opened <br /> Depth-to-groundwater was measured in each of the wells using a water level indicator capable of <br /> measuring groundwater to within 0 01 foot <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 Fallowing 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 /> documentation to Kiff for analysis Kiff analyzed each of the groundwater samples for TPH-as- <br /> gasoline, BTEX, MTBE, DIPE, ETBE, TAME, TBA, 1,2-DCA, and 1,2-dibromoethane (EDB) by <br /> EPA Method 8260B <br /> 2 2 4 Waste Storage and Disposal <br /> Waste sod cuttings generated during the drilling operations were stockpiled on plastic sheeting <br /> and covered Based on the absence of gasoline constituent compounds in soil sample analyses <br /> performed during this investigation, the soil stockpile was uncovered and spread out at the site <br /> Waste liquid from equipment rinsate 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 September 7, 2000, Ramage Environmental collected a groundwater sample from the on-site <br />' water well for laboratory analysis Prior to sampling, the well was purged until the well pump was <br /> activated The groundwater samples were collected from the wellhead sampling port 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 water well sample for TPH-as- <br /> gasoline, BTEX, MTBE, DIPE, ETBE, TAME, TBA, 1,2-DCA and EDB by EPA Method 82608 <br /> 11 <br /> r <br />
