I 'II i� collector tube . All samples were collected by Dennis Allen, CEG. The soil samples were checkedj'for ',odor and obvious signs of contamination, described, capped with Teflon tape and plastic caps, wrapped and sealed with duct tape, labeled with well number, depth and sample number and placed in a, cooler supplied by FGL, which contained blue ice . Chain-of- custody forms were used and tests specified, BTEX and TPH(G) on all samples . These tests were to be to the latest standards given in the Tri-Regional , Guidelines; copies of which were supplied to FGL for clarity. :•These standards were also attached to WJH report # 2, the work proposal . The samples were hand delivered to FGL representatives by DRA. A short summary of FGL Q/A-Q/C procedures are attached. FGL is a California Certified laboratory and their qualifications have been filed both1with the State of California and San Joaquin County. i� Water Sample Collecting: April 10, 1991 ' General Data W. J.Hunter, R. Thorpe, M. Brock (FGL) arrived on location at 10: 15 for water sample collecting and to measure water levels . H. Knoll arrived during operations at a later time . All water levels were determined using an Oil Recovery Systems-Interface Probe (IP) , capable of detecting both product top and water top, if such situation exists . The IP and line were washed and rinsed betFieen „wells All three monitor wells had been surveyed to the high side of the protruding well casing and water levels were measured from this point. The bailer used for purging the wells was washed with TSP and rinsed between uses . The bailer cord was cut and replaced for each use. Chain-of��Custody forms were used and all samples were placed in a cooler using blue ice, supplied by FGL. All samples were collected in sterile 40 ml vials supplied by FGL and delivered! to the well site in the cooler. The metal cover and sealing well cap and lock were removed from each well prior to commencing operations and they were replaced after operationsl:were finished. a Monitor Well # 3 MW # 3 was uncovered at 10: 15 AM and the tap of fluid was located at 6 ' 8” (6.671 ) below the wellhead. The measurement was made six times to verify the depth. No floating product was found. (Note : these data must be converted to feet and hundredths ofi,a foot in order to utilize them with the surveyed data, 95 . 30 ' for this well ) . When rounded off to .00 ft. and using the elevation based on an assumed 100 ' standard, the water level in this well was 88 .53 ' . See Figure 1 for plots.,on all three wells . i 7
