r it <br /> ' !I <br /> Following liquid level measure ment;`'each of the wells will be purged and sampled. The wells will <br /> f J! it <br /> be purged with a pump and dedicated disposable tubing until at least three well casing volumes <br /> have been extracted and/or after groundwati r temperature, pH and electrical conductivity values <br /> have stabilized. Groundwater will be.sampled from the wells using dedicated and disposable <br /> itIWl � ;p <br /> bailers and laboratory-supplied containers. Each sample will be labeled, packaged in an iced <br /> cooler and transported with chain-of-custody documentation to a state of California-certified <br /> hazardous waste testing laboratory for analysis. All groundwater samples will be analyzed on <br /> standard turn-around for TPH-as-gasoline, BTEX, MTBE, DIPS, ETBE, TAME, TBA, 1,2-DCA <br /> and EDB by EPA Method 8260B. <br /> j <br /> �dq 11�i fi <br /> The results of the initial groundwater;;monitoting, sampling and analysis will be documented in <br /> the well installation project report. ITh results of the subsequent quarterly monitoring events will <br /> i' jli'� i.J 11 <br /> ` be documented in quarterly groundwater,monitoring reports. <br /> fi 2.3.6 Waste Storage and Disposal 1 <br /> All waste soil will be stockpiled on plastic sheeting, sampled, and covered, pending analytical <br /> results and proper disposition. Equipment rinsate and purged groundwater will be contained in <br /> 55-gallon drums for temporary on-site storage , pending proper disposition. <br /> 2.4 Environmental Site Investigation Report <br /> A project report documenting all of the;proposed work activities will be prepared and stamped by <br /> a state of California Registered Geologist and submitted to PHS/EHD and RWQCB. In addition <br /> to a standard discussion of methodp,j the re0ort will include the following: <br /> • Site location map and site plan; <br /> to i .. . E! <br /> l Tables summarizing cumulative analytical results; <br /> • Figure(s) depicting the extent of mpactel soil and groundwater; <br /> CPT and monitoring well logs and laboratory reports (Appendices) <br /> I$'L.1!; '4 - 1i <br /> • Recommendations for future environmental corrective actions. <br /> i <br /> b S <br /> I <br /> i 10 <br /> i <br /> I. <br />
