r <br /> PROPOSED MEETING AGENDA <br /> CHAPIN BROTHERS INC <br /> 1766 Monte Diablo Ave. <br /> Stockton, California <br /> Location: San Joaquin County Public Health Services - Environmental Health Services <br /> Date: 04 October 1999 <br /> Atte_ ndine: Mr. Russell Chapin - Property Owner/Responsible Party <br /> Mr. Mark List- RWQCB <br /> Mr. Harlin Knoll and Ms. Margaret Lagorio - PHS-EHD <br /> Mr. William Little and Mr. Robert Marty <br /> Advanced GeoEnvironmental, Inc. <br /> Proposed Discussion: <br /> 1. As presented in the previous quarterly report,the extent of the petroleum hydrocarbon impact <br /> to the ground water at the site has been well defined. <br /> 2. Over the monitoring period, the dissolved hydrocarbon plume has remained stable. <br /> 3. Additionally, the hydrocarbon plume concentrations, in both soil and ground water, have <br /> been considerably reduced over the site remediation period. <br /> 4. Soil gas have been reduced to concentrations below the detection limits of the soil vapor <br /> analytical method. <br /> AGE recommends the following: <br /> • Conduct a ground water monitoring. During this quarterly sampling event, collect water <br /> samples from selected wells to allow for the most representative ground water data (i.e. all <br /> vapor wells with screens in the current water table level and all ground water wells, also <br /> consider the sampling of air-sparging wells). <br /> • Prepare a request for certified site closure. <br /> • Abandon wells on and off the site. <br />
