sealed metal drums, properly identified, and stored on site. <br /> ' Details of lithology & other data is given on PLS. There <br /> was no evidence of contamination in the drill cuttings, core <br /> material, or groundwater. <br /> ' 2" Sch 40 flush---screw joint blank &. slotted PVC was run to 321 , <br /> and was gravel packed, sealed, & grouted to the surface as <br /> detailed on PLATE XI. <br /> ' After cementing well #42 the crew grouted the annular space in <br /> well #5 to the surface with cement. Precast boxes were installed <br /> and thoroughly grouted on both wells, and the 2" casings were <br /> ' left extended about 6" above the bottom of the boxes to allow <br /> placement of an expandable locking cap. The boxes were equipped <br /> with heavy duty traffic covers. <br /> ' All operations were supervised by Wm. Hunter, & grouting <br /> operations were witnessed by a representative of the San Joaquin <br /> ' LHD. <br /> Upon completion of activities, the preserved samples were trc-ms- <br /> ported under chain of custody to FGL laboratory with instructions <br /> to test for BTEC, (EPA 8020, ) & TPH-G, (EPA 8015N. ) ,A, copy of <br /> that custody sheet is included with the laboratory results as <br /> EXHIBIT C_ <br /> ' On September 28, 1994, both wells were developed, purged, . <br /> sampled by Deg-Tech Geotechnical Services. A copy of the report <br /> covering that work is included as EXHIBIT D. The laboratory <br /> ' sheets & custody chain are included as M1111T _ Water levels <br /> were measured for all five wells in order to determine the <br /> hydraulic gradient at the time of sampling the new resells. <br /> ' The results of the laboratory analyzes of soil samples are <br /> summarized on TABLE III, and show that all samples were below <br /> detection limits for BTEX & TPH-G. TABLE IV lists the results of <br /> ' the laboratory analyzes of the seater samples taken 9/28/1994, <br /> which shows that both wells were below detection limits. TABLE V <br /> slim mari es results of all mater samples taken to date. <br /> ' The surface elevations of the new wells were dot-ornined by <br /> Siegfried Engineering, licenced su--veyors; that data his included, <br /> ' as EXHIBIT F. <br /> Lasing the data from the 9/28/1994 water level measurements & the <br /> surveyed well elevations, a hydraulic gradient map was construct- <br />' ' ed, (P,.,ATR_ XII. ) which shows that the gradient continues to be in <br /> a northeasterly direction. There is a slight change in the <br /> direction of the contours, but this may be due to the spacing <br /> between measuring points_ <br /> 8 <br />
