r7 x KEI-P89-1104 .R1 January 8 , 1990 Page 3 feet. All samples were taken from bulk material excavated by backhoe, collected and handled as described above. These sample point locations are also shown on the attached Site Plan, Figure 2 . Mr. Harlin Knoll of the San Joaquin County Public Health Services was present during sampling. KEI again returned on December 7 , 1989 in order to complete sampling of the southerly half of the fuel tank pit. Two soil samples, labeled SW3 (20/13) and SW3 (20/19) , were collected from the tank pit sidewalls at depths of 13 and 19 feet, respectively. In addition, one soil sample, labeled NSW, was collected from the northerly sidewall of the new fuel tank pit at a depth of 13 . 5 feet. Again, all samples were taken from bulk material excavated by backhoe, collected and handled as previously described. Sample point locations are as shown on the attached Site Plan, Figure 2 . On December 13 , 1989, KEI completed sampling of the old fuel tank pit when three sidewall soil samples, labeled SW4 (3) SW5 and SW6, were collected from the northerly half of the old fuel tank pit at a depth of approximately 16 feet. Samples were taken from bulk material excavated by backhoe, collected and handled as described above. Sample point locations are shown on the attached Site Plan, Figure 2 . Also on December 13 , 1989, four additional samples of native soil , labeled P1 (6) , P2 (17) , P3 (5) and P4 (8) , were collected from the product pipe trenches at sample point locations P1, P2 , P3 and P4 , respectively. Sample depths ranged from 5 to 17 feet. Samples were collected from bulk material excavated by backhoe, taken and handled as previously described. Sample point loca- tions are as shown on the attached Site Plan, Figure 3 . After sampling, the product pipe trenches were excavated to the sample depths. Upon review of the laboratory analyses for these samples, a 15-inch diameter casing (14 feet deep) was installed near sample point location P2 (17) . After completion of the soil sampling on December 13 , 1989 , a water sample was taken from the on-site domestic well system after purging a minimum of three piping volumes. The sample was also taken only while the pump was operating to avoid drawing water from the holding tank. The sample was collected In six clean, glass VOA vials, with Teflon screw caps, sealed and handled as described above.
