aquifers are monitored at the GE well site. Well GE1 is <br />• completed in the GR aquifer. Figure 8-49 presents a fairly <br />steady plot with three outliers. Field conductivity data for <br />wells GEI and GE2 has shown little change with only a slight <br />increase in concentrations since 1985. This slight increase is <br />probably a natural variation at the GE site. Well GE3 shows some <br />of the slight increase in concentrations for the Second and Third <br />White Sandstone aquifers at the GE site since 1985, but with more <br />scatter in the data. This well is more susceptible to changes <br />because these sandstone aquifers are shallower. TDS <br />concentrations from well GE3 have varied similarly with time. <br />Changes in the field conductivities for aquifers monitored at the <br />GE site are not caused by any mining activities from Trapper <br />Mine. Mining on the west side of the Trapper Mine permit area <br />was re-started in 1988. Present Trapper mining activity is <br />approximately one mile away. <br />Twenty Mile well GF1 and U aquifer well GF2 have shown very <br />little change in field conductivity during the period presented <br />(1981 through 1988) in Figures B-52 and 8-53. Wells GF3 and GF4 <br />are completed in the KLM and I aquifers. Figures B-54 and B-55 <br />present the field conductivity versus time plots for wells GF3 <br />and GF4. Each plot shows no major trends in data to 1986 with a <br />slight rise in values since 1986. This slight rise is still <br />within natural fluctuations. <br />The backfill aquifer in the Ashmore Pit area is monitored by <br />well GFS. Figure 8-56 shows that conductivities for well GFS <br />• have been fairly stable since 1984 with one outlier in June, <br />3-12 <br />
