PLATE VIII is a lithologic plot of the sediments penetrated, and PLATE IX is a schematic diagram of the well completion details. After completion of operations, a tape was lowered into the casing & located water at about 9' below grade_ I The clean backfill material was placed on the ground away from the rig; drill spoils were placed in a metal drum which was tightly sealed; it was stored near the site away from traffic. Margaret Lagorio, Sr. REHS, from the San Joaquin County EHD, was on location during the majority of the activity, which was supervised by Wm. Hunter of WJH. Upon completion of the well, the geologist transported the preserved samples to FGL Environmental laboratory under chain of custody, with instructions to test for BTEX & TPA-G using County approved detection limits. On November 21, Don Light of Del-Tech Geotechnical Support developed, purged & sampled the well. It was developed by purging with a 3' stainless bailer on a wireline bailer spool. • The bottom the well was tagged at 21 . 52' at start of operations. A total of 23 gallons of water was removed from the well during development_ Bottom was located at 23. 20 ' after purging and cleaning of the casing. After well conditions had stabilized, water samples were taken with a clean, 1 ' long stainless steel bailer; they were placed in preserved glass vials & preserved for shipment. The well was thoroughly secured after completion of the work. The water samples were delivered to FGL Environmental under chain of custody with instructions to test for BTEX & TPH-G. A copy of the field report covering this work is included as EXHIBIT Q. The results of the laboratory analyzes of soil & water samples are summarized on TABLES V & VI. It shows that both soil & water below detection limits for BTEX & TPH-G. The laboratory sheets & chains of custody are attached as EXHIBITS Q& P. On December 21 , 1994, the well was again purged & sampled by Del-Tech as detailed in EXHIBIT R, and the preserved water samples delivered to FGL for analysis. However, due to a clerical error at the lab, the samples were not analyzed as ordered. When the mistake was discovered, the holding time for the samples had expired. Rather than complete the analysis, it was decided that another sampling event would be the best way to obtain valid samples. On January 23, 1995, Del-Tech Geotechnical Support Services again 6
