A review of the tank removal inspection report by PHS/EHD staff indicates that the <br /> sample depth in tank 1 was 15 feet for sample 1W, 15.5 feet for sample 1E and 2.5 feet for the <br /> pipeline sample. Sample depth in tank 2 was 17 feet for both the North and the South sample. <br /> Figure 2 of the workplan shows the relative locations of the two proposed borings and the <br /> location of the former waste acetone tank. The text of the workplan says CE-1 will be drilled <br /> near the east end of former product Tank 1 and CE-2 will be drilled near the north end of <br /> former waste acetone Tank 2. PHS/EHD concurs that these proposed locations will resolve the <br /> question of contamination located near T1-E taken July 18, 1989 and TI-N taken December 20, <br /> 1989. <br /> A review of the tank removal results by PHS/EHD staff indicates that contamination is also <br /> present at the west end of former product Tank 1 as indicated by the results of the analysis of <br /> T1-W taken July 19, 1989 and the pipeline between the former dispenser and the former fill end <br /> of Tank 1 as indicated by the results of the analysis of P1 taken July 19, 1989. PHS/EHD staff <br /> has determined that these areas are not addressed in this workplan. <br /> PHS/EHD has issued drilling permit #006321 to Spectrum Exploration, Inc. On site <br /> implementation of this workplan should be scheduled by _ <br /> l <br /> A Division of San Joaquin County Health Care Services <br />
