PHS/EHD has the following comments for your <br /> consideration. <br /> PHS/EHD cannot concur with the recommendation that the site be closed based on <br /> available information. Groundwater contamination continues to be evidenced, although not <br /> reported in the above mentioned report. As PHS/EHD indicated in correspondence dated <br /> June 24, 1993 and September 24, 1993, residual soil contamination remaining at the <br /> completion of the excavation attempt may require additional investigation and/or <br /> remediation. Significant contamination has been evidenced in the area of former tank #1 <br /> and #2 which requires additional investigation to determine its extent. PIease submit a work <br /> plan by May 25, 1994 to continue the soil investigation. <br /> The confirmation soil samples did not undergo EPA Method 8020 as published. Extensive <br /> modifications of the Method occurred which were not approved. <br /> PHS/EHD discovered a number of errors in the presentation of data submitted by TEG. <br /> PHS/EHD has prepared the following summary of those errors. <br /> 1. Table 1 in the above mentioned report incorrectly represented results of <br /> laboratory analysis of sample, E72N1, the lab reported 0.0380 xylene instead <br /> of 0.380 xylene as the table indicated. <br /> 2. Tank #1 area <br /> Sample, W97S, collected on October 7, 1993 at 6 feet, evidenced soil <br /> contamination; however, its location was not indicated on Figure 4. <br /> A Dkision of San Joaquin County Health Care Services <br />
