In 1976 there were several additional samples of <br />Town water analyzed for nitrates, and the results are also included in <br />Table IV-la, Apparently, there was some dilution of the high nitrate water <br />from the shallow wells with low nitrate water from the deep well as evidenced <br />by the samples taken on the east side of Town (Mel Ko~na's house, east end <br />of Town, and the east side garage). <br />As part of this study, all past water quality data was obtained for <br />the Nunn area from larious sources including the U.S.G,S, and the State <br />Depcrtment of Health. Tables IV-la and Ib present a summary listing of the <br />data which was obtained. Figure IV-1 shows the location of the wells for <br />which water quality data is available. A sampling program was undertaken <br />during the current study to obtain additional water quality data from wells <br />in the Nunn area, p3rticularly in regard to the concentration of nitrates, <br />The results of the tests and the locations of the sampling pOints are shown <br />in Table IV-lb and Figure IV-I, respectively. The location of the sampling <br />points where the nitrate concentration was less than the mandatory limit of <br />45 mg/l (as N03-) i; shown in Figure IV-I. As can be seen, the concentration <br />of nitrates in water from the shallow wells is much lower to the east and <br />northeast of Nunn, in the Lone Tree Creek drainage area. Typically, high <br />nitrate concentrations occur in the wells located in the Spring Creek <br />drainage area, but the level decreases northward up the basin from Nunn. <br /> <br />16 <br />
