<br />' Water Quality - The water quality data is summarized in Tables 15 to 20 for the <br />Foidel Creek wells and Tables 21 to 28 for the Fish Creek wells. The historic <br />dissolved solids concentrations for the Foidel Creek wells are plotted on Figure <br />16. The historic dissolved solids concentrations for the Fish Creek wells are <br />plotted on Figures 17 and 18. Seasonal variation is evident in only those wells <br />with relatively high dissolved solids concentration. This is due to flushing <br />' effect of the relatively low dissolved solids surface water which recharges the <br />alluvial aquifers during spring runoff. <br />The dissolved solids in the Foidel Creek alluvial well downstream of the mine <br />discharge (001-5-5) have not increased since the underground mine opened. The <br />dissolved solids in the well immediately upstream of the mine discharge (001-5-6) <br />have increased from approximately 1200mg/L to almost 2000 mg/L. Therefore no <br />' effect from the underground operation is evident. Since there are no discharges <br />from the underground mine to Fish Creek there are no impacts from the mine. The <br />water quality data on the Fish Creek alluvium is presented for baseline purposes <br />only. <br /> <br />r <br />
