Well design and construction will be in accordance <br /> with SJCEHD and RWQCB guidelines . The top of each <br /> well shall be secured with locking caps and <br /> christy boxes finished flush with the ground <br /> surface . <br /> Task 1 . 5 : D velo-o, aample, and Survey MonitQjLlncr Wella <br /> The additional monitoring wells will be properly <br /> developed and sampled, in accordance with SJCEHD <br /> and RWQCB guidelines . Water samples will be <br /> collected from each of the wells and placed in <br /> sterile containers for transport to a <br /> state-certified laboratory for analysis . <br /> All the additional wells will be surveyed as to <br /> location and elevation in reference to an <br /> established benchmark or a common datum to within <br /> 0 . 01 foot . water level at each well will be <br /> measured as well as any free floating product . <br /> Task 1 . 6 : Analyze S9il and Ground,.,WatQr Samples <br /> Soil and ground water samples will be transported <br /> to a state certified laboratory for analysis <br /> following proper chain of custody procedures . <br /> Soil samples will be analyzed for TPH as gasoline <br /> with BTEX distinction, by EPA method 8015/8020 . <br /> Water samples will be analyzed for the same <br /> constituents as above, using EPA methods 8015/602 . <br /> All samples will be analyzed on a standard two <br /> week turnaround time. <br /> Task 1 . 7 : Analyze Data and Laboratory Results <br /> Upon completion of the sample analysis and <br /> background research, a detailed evaluation of <br /> results and available information will be <br /> conducted to determine the extent and nature of <br /> subsurface contamination following the 5-step <br /> investigative process of RWQCB. This will <br /> include : <br /> - Interpretation of geologic and hydrogeologic <br /> information and analysis of aquifer <br /> characteristics . <br /> - Preparation of ground water level contour <br /> maps, geologic cross sections, and hydrocarbon <br /> concentration maps . <br /> -- Definition of hydrocarbon contamination plume . <br /> - Assessment of the potential short- and <br /> long-term impacts of contamination on the <br /> beneficial uses of ground and surface water. <br /> 5 <br />
