similar sequence of soils was encountered in monitoring well 2. <br /> The soils encountered in monitoring well 3 below 11 feet were <br /> composed of clay to approxivately 24 feet underlain by silty <br /> sands to 30 feet. <br /> Groundwater was initially encountered during drilling at <br /> approximately 16 feet in monitoring wells 1 and 2, and approxi- <br /> mately 13.5 feet in monitoring well 3. Measurements taken <br /> subsequent to drilling on November 5 and 13, 198G, showed the <br /> depth to water was approximately 11 ftet i, all the wells. The <br /> closest surface water bodies are the Calaveras River approxi- <br /> mately 1 mile to the north and Smith Canal less then 1/4 mile to <br /> the south. Both the Calaveras River and Smith Canal flow into <br /> the San Joaquin River which passes within 1-1/2 miles of the site <br /> to the southwest. <br /> SOIL COYTAKIAATION <br /> duri�St.onG)hydrocarbon odors were noted by Lie project geologist <br /> g Aeilling and soil sampling and the results of laboratory <br /> analyses indicated the presence of hydrocarbon in the soils. <br /> The highest hydrocarbon concentration was 4.1 parts per million <br /> (ppm) in the sample obtained at a depth of 9 feet in monitoring <br /> well 1. The hydrocarbon concentrations in samples obtained at a <br /> depth of 10.5 feet in monitoring well 2 and 9 feet in monitoring <br /> well 3 were 3.3 and 1.5 ppm respectively. The laboratory <br /> analyses results show that the hydrocarbons encountered in <br /> monitoring wells 1 and 2 consisted of gasoline components and <br /> those present in monitoring well 3 were diesel. The laboratory <br /> analysis results are shown in Table 2 below and the laboratory <br /> report is presented in Appendix III. <br /> COPY <br />
