!` <br />Conductivities presented on Figure B-3 present a fairly steady <br />plot of conductivity for well GB2. Figure B-4 presents the <br />conductivity versus time plot for well GB5. Conductivities for <br />the well GB5 during the last few years have remained fairly stable <br />although approximately 200 micromhos lower than earlier data. <br />Changes in the Third White Sandstone aquifer at this well are <br />thought to be within the range of natural fluctuation. These <br />changes in conductivity in water from well GB5 are probably <br />natural but could have been influenced some by the adjacent <br />mining. <br />Well GC1 monitors the H aquifer at the GC site on the far <br />east side of the Trapper Mine permit area at least two miles from <br />the active mining. Figure B-5 presents the conductivity data for <br />well GC1. Concentrations have been very steady from this well in <br />1989 and 1990. Well GC2 is completed in the Third White Sandstone <br />at the GC well site. Figure B-6 shows some scatter in the <br />conductivity data while an overall slight increasing trend seems to <br />be occurring. This increase in conductivity is natural. The <br />alluvial aquifer is monitored at the GC site by well GC3. Figure <br />$-7 presents the conductivity versus time plot for well GC3. A <br />fair amount of scatter is seen on the plot. but an increase in <br />values was seen from 1984 to 1986 with stable values after the <br />rise except for the 1990 value which shows a'slight increase. All <br />changes in th'e aquifers at the GC .site are natural due to -the. ' <br />distance from active mining. <br />Well GD1 is a Twenty Mile Sandstone well and is used as the <br />3-2 <br />
