r bottom tube was promptly preserved by covering the ends with teflon tape & plastic caps, and thoroughly sealing with duct tape . The tube was labeled, placed in a ziplok bag, and placed on ice pending transport to Sherwood labs for analysis . A water sampling tool was pushed into the satuated zone approximately 1 1/21 and the screen was extended to allow collection of a water sample . Entry was very slow, so the screen was left in the hole, and equipment was thoroughly decontaminated. The truck was moved to the location for SP-2 as shown on PLATE II . The soil probe was pushed to 261 bgl, taking soil samples at 51 intervals from 51 to 251 bgl as described above . A clean water sampling tool was then lowered into the hole and pushed to approximately 271 Water samples were obtained by use of a clean stainless steel baler, and placed in 2 VOA' s & a 1 liter bottle which had been provided by the laboratory They were labeled and stored on ice pending transport After cleaning equipment, the probe unit was mobilized on loca- tion SP-3, (see PLATE II, ) and soil samples were collected at 51 intervals from 51 bgl to 201 , they were preserved as described above . A water sampling tool was pushed to 221 and groundwater was retreived and placed in 2 VOA1s and a 1 liter bottle They r were labeled and preserved on ice After decontaminating equipment, the probe truck was moved to location SP-4, (see PLATE II for it ' s location, ) and soil samples were collected at 5 ' intervals from 51 bgl to 251 bgl using the sample field procedures described earlier. Tools were then pushed to 30 1/21 , where water samples were collected as described above . After completing the above work, a clean bailer was lowered into the screen left in SP-1 to see if there was sufficient water entry for collecting samples . Entry was slow, and with the approval of Linda Turkatte of the San Joaquin County EHD, the hole was left open with the pipe & screen, (top covered, ) until the following day Soil probe locations SP-2, SP-3 , & SP-4 were grouted from total depth to the surface with cement, and opera- tions were suspended. There were no product odors detected in any of the soil or water samples . Refer to PLATES III, IV, V, & VI for soil sample descriptions . The preserved soil & water samples were trans- ferred to an employee of Sherwood Labs and transported to that facility under chain of custody; instructions were given to test for BTEX w/MTBE distinction, TPHg, and TEPH Operations began again on April 12 under the supervision of Charles Fry, RG; a bailer was lowered into SP-1, and sufficient 2
