Airport Way <br />Stockton CA 95206 <br />San Joaquin County Environmental Health Department (SJC/EHD) has reviewed <br />Preliminary Site Assessment Work Plan (Work Plan) dated March 15, 2007, submitted on <br />your behalf by Advanced GeoEnvironmental, Inc. (AGE) and has the following comments. <br />In the Work Plan AGE proposes to continue the investigation of the vertical extent of the <br />contamination at this site with a cone penetrometer test (CPT) boring located near the <br />east end of the former tank #2 location. The proposed depth of the boring is 100 feet <br />below surface grade (bsg), but it will be extended if obvious signs of contamination are <br />present. Soil and grab groundwater samples will be collected for analysis from <br />appropriate lithological units. Previous work at this site has documented contamination in <br />this area to 65 feet bsg in the soil (boring B-1), and to 50 feet bsg in the groundwater (B-1, <br />MW -1, MW -2 and MW -3). The vertical extent of the contamination in both soil and <br />groundwater remains undefined. <br />The lateral extent of the contamination will be investigated with the installation of three <br />shallow groundwater monitoring wells. AGE proposes to install the wells to the east, or <br />downgradient, of the existing monitoring wells. Total depth of the wells will be 50 feet bsg <br />with 20 feet of screened casing. Soil samples for analysis will be collected to total depth <br />of the borings. <br />SJC/EHD approves the proposed CPT boring and monitoring well installations and <br />locations. Please proceed with submittal of a San Joaquin County Well Permit <br />Application, required $89.00 permit fee and $285.00 permit inspection fee for each C-57 <br />licensed contractor who will perform work at the site. <br />In correspondence dated March 2, 2007 you were directed by SJC/EHD to resume routine <br />quarterly groundwater monitoring at your site. AGE has verbally confirmed that routine <br />monitoring and sampling will resume April 12, 2007. Routine quarterly groundwater <br />monitoring and sampling at this site must continue until directed otherwise by this agency. <br />You have also been directed to submit all site data and reports to Geotracker, the State <br />Water Resources Control Board database website, but none have been. Please proceed <br />with immediate submittal of all site data and reports to Geotracker. <br />
