sr <br />.x <br /> P <br /> Julian Munoz r <br /> 10 June 1957 7 w ISSASSOCOTES <br /> The boring permit issued by the San Joaquin Local Health District (SJLHD) <br /> requires that ground water monitoring wells will be installed if hydrocarbons <br /> are found in the subsurface. Since hydrocarbons were found in saturated soil, <br /> ground water monitoring wells will be required at the site. <br /> RECOMMENDATIONS <br /> To comply wi,:h SJLHD requirements for monitoring well installation, we <br /> recommend a Phase II investigation at the site. The objective of this phase <br /> is to determine the extent of hydrocarbons in ground water and to further <br /> define the vertical and horizontal distribution of hydrocarbons in soil. The <br /> proposed workscope for Phase II is: <br /> Task 1) Drill three borings, collect soil samples at 5-ft intervals, <br /> analyze one sample per boring and install three 4-in, diameter <br /> ground water monitoring wells in the boreholes. <br /> Task 2) Develop the three wells, collect and analyze samples of ground <br /> water and development water. <br /> f <br /> Task 3) Prepare a report that summarizes all previous work and presents <br /> the results, conclusions and recommendations. <br /> Each of these tasks is described below and a detailed cost estimate is <br /> presented in the attached budget. <br /> TASK 1 - SOIL SAMPLING AND MONITORING WELL INSTALLATION <br /> Three borings will be drilled to an anticipated depth of 40 ft. A WA <br /> field geologist will log the borings and collect soil samples every 5 ft to <br /> documenC subsurface hydrogeologic-- --conditions---and -for- -possible chemical - - <br /> analysis. All soil samples will be submitted to an analytic laboratory and <br /> - one saturated soil sample � .r boring will be analyzed by GC/FID for TFHC and <br />
