• <br />This hole was sampled during the pumping test and yielded the <br />following parameters: <br />Temperature = 13° C <br />pH = 6.5 <br />Conductivity = 950 @ 13° C <br />• <br />The sample was sent to a laboratory for analysis. <br />HOLE N0. M-4 <br />Drilling <br />Hole No. M-4 was drilled on May 7 and 8 to a total depth of 247 feet <br />and completed as shown in Figure 3. Ground water was encountered at <br />about 80 feet and between 235 and 240 feet. The upper flow was suc- <br />cessfully cased and isolated from the hole. <br />Testing and Sampling <br />Hole No. M-4 was tested by pumping for 19 hours at 30 gpm. Both <br />drawdown and recovery were measured. The drawdown and recovery por- <br />tions of the test each resulted in two slightly different transmissi- <br />vity values (Exhibit 7). <br />Drawdown <br />t = 0-70 min <br />t = 70-1140 min <br />303 gpd/ft <br />176 gpd/ft <br />Recovery <br />273 gpd/ft <br />162 gpd/ft <br />n <br />LJ <br />
