Each well was Initially sounded with <br /> an electric Interface probe to determine the ground water level in the well, and <br /> l total depth of the well. A minimum difference of 2.5 feet between the bottom <br /> of the well and the ground-water level in the well was required for slug <br /> testing. This criteria was necessary in order to place the pressure transducer <br /> 5 <br /> I' In enough column of water to allow the instrument to function properly once <br /> I the slug was removed. This criteria was met in the three well,; tested (MW-22, <br /> MW-30, and MW-31). <br /> The procedure for conducting each slug test consisted of the following steps. ' <br /> x First, the ground-water level in the well and total well depth were measured, <br /> and the downhole pressure transducer was placed in the well to a depth Just <br /> s f¢ Dove wail bottom. The data collection unit was programmed to allow the <br /> ground-water level An the well to attain equilibrium following pressure <br /> transducer insertion (measured directly b the transducer).er). Next, the sluff was <br /> Inserted and the' ground-water level in the well was allowed to re-equilibrate. <br /> F <br /> The. slug was then removed while instaneously starting the data collection <br /> program. Rising ground-water levels were measured up #0 18 minutes for each <br /> test. Following each test; the transducer, cable and slug were washed In a <br /> mixture of trisodlum phosphate and distilled water, rinsed in distilled water, <br /> and allowed to air dry prior to conducting another test. <br /> Ti <br /> i <br /> -- _ 7F .. <br /> c t <br />
