1 <br /> 1 <br /> auger flights were pulled, sand depth was monitored to avoid the <br />' possibility of bridging. After verifying that the sand pack was <br /> at 521 , (three feet above the top of the perforations, ) 1 1/2 <br /> buckets of bentonite pellets were poured on top of the sand & <br /> wetted with sufficient water to expand the material. The <br /> bentonite was located at 50 ' , 2' above the sand pack_ After <br /> pulling the augers, the annular space between the 2" PVC & the <br /> open hole was filled with 12 sacks of cement which was mixed on <br /> 1 location and placed in the annulus_ The completion operations <br /> were supervised by Mr. Hunter, & witnessed by Steven Sasson of <br /> the San Joaquin EHD. Mr. Hunter left the location at 1700; Mr. <br /> Sasson remained to witness the grouting of the well. A preformed <br />' vault and traffic cover were installed on the well, and the <br /> casing was secured with an expandable locking plug. Details of <br /> the well completion are shown on PLATE IX. <br />' On October 3, Del-Tech Geotechnical developed, purged, & sampled <br /> the well as instructed by WJH. A total of 9 gallons of water was <br />' purged from the well using a 1" stainless steel bailer. Water <br /> depth was measured at 53' , about 7' higher than indicated during <br /> placement of the well. It was noted that the water was quite <br /> turbid with a brown color, a heavy gasoline odor was noted and a <br /> PID meter recorded a reading of 718 ppm when the casing was <br /> opened. Water samples were obtained by use of a clean stainless <br /> steel bailer, and were transported undr chain of custody to FGL <br />' with instructions to test for BTEX & TPH--G. Refer to EXHIBIT D <br /> for details of that work. At the request of Mr. Sasson of the <br /> San Joaquin County EHD, a test for halogenated volatile organics, <br /> ' (EPA 601, ) was added to the chain by Mr_ Hunter via telephone. <br /> RESULTS OF LABO TOEY ANAYZSES OF SO L & WATER SAMPLES: <br /> ' TABLE VIII summarizes the results of the analyzses for the soil <br /> samples taken during placement of the well. BTEX & TPH-G were <br /> ' not detected in soil samples taken at 26' & 31' , but were present <br /> in all samples from 36' to 56' ; (that analysis was not run on the <br /> samples collected at 16' & 21 ' . ) The soil sample at 60' did not <br /> reveal any contamination, even though there was a definite petro- <br /> leum odor in the core Only about 3" of material was recovered, <br /> and this small amount of sample may have prevented an accurate <br /> measurement of constituents_ <br /> ' TPH as waste oil was present in soil samples at 16' & 21' , but <br /> were below detection limits in all samples below 21 ' . <br /> ' Copies of the laboratory sheets & chain of custody are included <br /> as EXHIBIT E. <br /> TABLE IX summarizes the laboratory results of the water samples <br /> 8 <br />
