All groundwater samples detected petroleum hydrocarbon <br /> contamination. <br /> PHS/EHD requested in correspondence dated September 15, 1992 that QA/QC data <br /> sheets be submitted with quarterly reports; however, QA/QC data sheets were not <br /> included in the above mentioned quarterly monitoring report. Please be informed that <br /> PHS/EHD has requested QA/QC information from Alpha Analytical Laboratories. <br /> QA/QC data sheets should be included in all future quarterly monitoring reports. <br /> The groundwater contamination plume has not yet been defined. <br /> PHS/EHD requested in correspondence dated September 15, 1992 that a work plan be <br /> submitted by November 16, 1992, in order to continue the groundwater investigation. To <br /> date PHS/EHD has not received the requested work plan. Please submit by February <br /> 22, 1993, a work plan to install a minimum of two additional monitoring wells. If you are <br /> unable to meet due dates, please submit a written request for a due date extension. <br /> Once soil and groundwater contamination has been defined a problem assessment report <br /> (PAR) should be prepared evaluating soil and groundwater remedial alternatives. <br /> A Division of San Jornquut Counry xeaith rare Semces <br />
