All { <br /> casing joints are threaded and no glues, chemical cements, or <br /> solvents were used in well construction. The top of the casing <br /> is covered with a slip cap and the bottom has a threaded end <br /> plug. ' <br /> The annular space of each well was backfilled with 43 Monterey <br /> sand from total depth to approximately 2 feet above the screened f <br /> _rr <br /> casing. A bentonite plug, approximately 2 fest thick, was placed <br /> abOVe the sand as a seal against cement entering the sand pack, t <br /> and the remaining annulus was backfilled with neat cement to <br /> grade.
