PUBLIC HEALTH SERVICES <br /> SAN JOAQUM COUNTY <br /> ENVIRONMENTAL HEALTH DMSION <br /> Karen Furst,M.D., M.P.H., Health Officer <br /> 304 East Weber Avenue,Third Floor- Stockton, CA 95202 <br /> 209/468-3420 <br /> PY <br /> MARLA GUENSLER C(O <br /> EXXON COMPANY USA FEB 2 7 10 <br /> PO BOX 4032 <br /> CONCORD CA 94524-4032 <br /> RE: Exxon #73708 SITE CODE: 1072 <br /> 2705 Country Club Blvd. <br /> Stockton, CA., 95204 <br /> San Joaquin County Public Health Services, Environmental Health Division <br /> (PHS-EHD) has reviewed the "Quarterly Ground Water Monitoring Report, <br /> Fourth Quarter 1997" dated January 6, 1998 as submitted by Delta <br /> Environmental to PHS-EHD on January 20, 1998 and has the following <br /> comments. <br /> Of the eight monitoring wells sampled on November 24, 1997, only MW-7 did not <br /> contain any gasoline constituents. Analysis by EPA Method 8260 indicated that <br /> all of the seven other wells contained MTBE and only MW-3 noted Benzene at <br /> 1.0 ugA (ppb). With this current low level of contaminants noted across the site, <br /> PHS-EHD is re-evaluating this site for remediation. <br /> In a phone conversation with Mr. Keoni Almeida of Delta Environmental on <br /> November 17, 1997, Mr. Michael Infuma (PHS-EHD) discussed his review of <br /> Exxon's "Pilot Testing Results and Proposed Remedial Action Plan" dated <br /> August 20, 1997 as submitted by Delta to PHS-EHD on October 27, 1997. The <br /> items discussed included the possible "source" of Benzene only contamination <br /> noted only in MW-3, the lateral limit of the groundwater plume in the down- <br /> gradient direction, and that currently no soil data exists from 20 feet below <br /> ground (the historical deepest depth to first groundwater). <br /> Mr. Infuma advised that once the site was fully assessed he would review the <br /> results of feasibility studies (including the actual cost and time breakdown) that <br /> were to be contained in a Corrective Action Plan (CAP) that is to be submitted to <br /> PHS-EHD for review. <br /> A Division of San Joaquin County Health Cue Services <br />
