Well GP4 is also a flowing well that is completed in the KLM <br /> f <br />F <br />l <br />ti <br />iti <br />f <br />P4 <br /> aqui <br />er. <br />d conduc <br />v <br />or well G <br />relate very well to <br />ie <br />es <br /> the TDS data for this well. The data presents a fairly steady <br /> plot with data staying close to a value of 1200 umhos/cm (see <br /> Figure 8-63). Wells GPS and GPb are the westernmost wells of the <br /> GP well series being slightly less than one-half mile from active <br /> mining. Both wells are completed in the OR aquifer with well GP6 <br /> approximately 5000 feet upgradient of well GP5. Field <br /> conductivity plots for each well present fairly stable plots of <br /> the data with average values of 1600 umhos/cm for well GPS and <br /> 1000 umhos/cm for well GPb showing that the downgradient well is <br /> subject to higher concentrations of dissolved solids from <br /> material in the OR aquifer between the two sites. Although these <br />• wells are relatively close to active mining, changes seen in <br /> these wells are natural fluctuations. <br /> Wells GP7 and GPB are HI and KLM aquifer wells in the <br /> easternmost area of the Trapper Mine permit. Conductivity plots <br /> for each of these wells present significant scatter through 1986 <br /> (see Figures B-66 and B-67). This variation in the early data is <br /> probably due to the differences in bailed water samples and <br /> pumped samples from the September monitoring each year, The <br /> pumped sample data for each well corresponds well to the <br /> individual TDS plots showing fairly stable data during the <br /> presented period (1985 to present). <br /> The Third White Sandstone aquifer is monitored by well GP9 <br /> in the northeast portion of the Trapper permit area.
