i <br /> retrieved, placed on a clean working surface on the support <br /> truck, and carefully opened by the geologist Recovery was 15" <br /> of brown to dark brown clay loam The bottom tube was promptly <br /> sealed with teflon tape & plastic end caps, securely wrapped with <br /> duct tape, labeled, & placed on ice in a sealed chest pending <br /> transport to FGL Environmental for analysis The remaining core <br /> material was described, examined for possible contamination, and <br /> disposed of in the barrels used to contain the drill cuttings <br /> While the second core barrel, (previously cleaned & filled with <br /> metal sleeves, ) was being used, the first one was decontaminated <br /> with a TSP/water solution rinsed twice with clean water, filled <br /> with new metal sleeves, and set aside until needed <br /> Additional cores were taken from 101 - 111611 , and 151 - 1616" as <br /> described above The cores were examined, logged, and preserved <br /> per standard WJH field procedures Refer to PLATE VII for a <br /> complete description of blow counts, recovery, lithology, and <br /> other pertinent details A weighted tape was lowered into the <br /> augers and found water at 1016" The augers were then advanced <br /> to 25 ' bgl for completing as a groundwater monitoring well <br /> 211 , Sch 40, flush screw-thread PVC casing was assembled and <br /> lowered into the auger flights the bottom 20 feet consisted of 3 <br /> rows of 020" horizontal machine cut slots with a sold screw-on <br /> cap on bottom; the top 5 feet was blank The casing was landed <br /> at 25 , bgl, with the top of the screened interval at 5 feet below <br /> ground level The annular space between the auger flights & <br /> casing was filled with #3 SRI graded gravel which was poured from <br /> the surface. The casing was continually vibrated during place- <br /> ment to prevent the possibility of bridging The depth of the <br /> gravel was checked with a weighted tape, as the annular space <br /> filled, auger flights were withdrawn from the hole A total of 8 <br /> sacks of sand was used to fill the annulus When the sand pack <br /> had reached 3 1/2 feet, 1/2 bag of bentonite pellets was poured <br /> down the annulus and located at 2 feet below grade It was <br /> wetted with approximately 2 gallons of water The hole was <br /> covered with a metal drum awaiting grouting at the completion of <br /> operations Refer to PLATE VILA for a schematic diagram of <br /> completion details <br /> The rig was moved to the location marked for monitoring well #3 <br /> as shown on PLATE VI After cutting through the asphalt, <br /> drilling began at 1035 hours, surface sediments consisted <br /> primarily of tan to light brown clay loam. At a depth of 5 feet, <br /> the blanking plug was retrieved, and a decontaminated core barrel <br /> filled with clean metal sleeves was lowered into the auger flight <br /> • and driven from 5 ' to 616" with the drive hammer, blow counts <br /> 5 <br /> I <br />
