PHS/EHD and the Central Valley Regional Water Quality Control Board <br /> (CVRWQCB) will consider sites for conditional closure with minor soil contamination. <br /> Enclosed you will find an "Addendum to Appendix A' dated October 7, 1993 which outlines <br /> the information necessary for closure evaluation. <br /> Regarding the request for recommendations for the location of soil boring, PHS/EHD has <br /> indicated in correspondence dated November 12, 1993 that at minimum two additional soil <br /> borings would be necessary to provide the vertical and horizontal extent of residual <br /> contamination. The issue of residual soil contamination arose as a result of contamination <br /> which was documented during the installation of MW2 and MW3. The work plan which is <br /> to be submitted should include a rational for the proposed locations of these soil borings <br /> incorporating the results from the tank removals, the excavation and the monitoring well <br /> installations. <br /> Quarterly Monitoring <br /> The last quarterly monitoring report which PHS/EHD received was dated April 1993 and <br /> included the results of March 1993 groundwater sampling. PHS/EHD has information which <br /> indicates that for two quarters groundwater has not been impacted by petroleum <br /> hydrocarbon contaminants. Please submit the quarterly monitoring report which includes <br /> the most recent groundwater sampling event which occurred in September 1993. If the <br /> September 1993 results are non-detect, an additional sampling event will be necessary to <br /> confirm that groundwater is no longer contaminated. <br /> A Division of San Joaquin Counry Health Fare Services <br />
