Center Street Stockton, CA Site Code : 505309 Owner: Roger Huckins 3501 Oak Grove Circle Stockton, CA 95209 Dear Mr. Infurna, Please find below the partial report of findings for the work completed to date under the Work Plan dated 9/28/1998 and modified 10/ 19/1998 for the subsurface investigation of the above property owned by Mr. Huckins. Due to the lack of funds, monitoring wells MW4A and M W4B have not been installed. BACKGROUND INFORMATION History Three underground tanks were removed from the above stated site by Jim Thorpe Oil on 10/26/94. At that time, ten soil samples were taken from the excavation spoil, the underground tank excavation, and the product piping area and analyzed by GeoAnalytical Labs. The samples from all three tanks showed evidence of gasoline contamination. The sample from the west end of tank number three (See attached analysis) was the most contaminated. After samples were taken, the excavations were backfilled to finish grade. Under Work Plan 1 for the site, a hollow stem auger soil boring (PB 1) was placed in the general area of Tank #one and Tank #2 to a depth of thirty feet on 4/28/98 . Samples were taken at depths of 8', 14', 25 ' and 30' and each was analyzed for BTEX, TPHg, and MTBE. All samples were contaminated with high levels of gasoline (see attached -Recap of Chemical Analysis). A hollow stem auger soil boring was also placed in the area of Tank #three to a depth of fifty feet. Samples were extracted at five foot intervals and all were analyzed for BTEX, TPHg, and MTBE . All samples were found to be contaminated with gasoline. MTBE was not found in any of the samples I
