February 13, 1988 AGS Job No. 2005-p <br /> Delta Truck Sales, Stockton, California <br /> Number 3 Monterey sand will be placed into the annular space of <br /> the well opposite the slotted interval through the hollow stem of <br /> the auger to a point approximately 5 feet above the slotted <br /> interval . A 2- to 3-foot plug consisting of bentonite pellets <br /> will be placed at the top of the gravel pack to prevent sanitary <br /> seal material from entering the sand pack, and the remaining <br /> annulus filled to just below surface grade with a bentonite- <br /> cement slurry. <br /> The well head will be fitted with a locking steel cage and a cast <br /> aluminum utility box set slightly above grade. The utility box <br /> is equipped with a watertight seal. This combination will reduce <br /> the likelihood of surface water entering the well and of <br /> unauthorized disturbance. <br /> The well will be developed by air jetting, swabbing, and pumping <br /> until clear water is obtained. After recovery to static <br /> conditions, ground-water samples will be collected after purging <br /> operations. Purging will be conducted using a submersible pump <br /> until at least two well volumes are removed and until stable pH, <br /> conductivity, and temperature readings are obtained. <br /> 14 <br /> f <br />
