. An increase in the dissolved solids in Williams Fork Alluvium Well <br />AVF-3 appears to have leveled off. The cause of this increase is <br />unknown; however, the data indicates that it is not from the mine <br />discharge or from the waste water lagoon. <br />The increased TDS in the 7 North Angle Discharge seen in 1991 <br />remained approximately the same in 1992 averaging about 1290 mg/1. <br />This increase in TDS was due to the accumulation of water in the <br />North Angle Sump location which was able to equilibrate with <br />oxidized rock within old workings and rubbelized rock within <br />subsidence panels. The maximum concentrations of 1474 mg/1 <br />represents this equilibrium concentration. Concentrations appear <br />to decrease when the pump has been running. <br />Flow from the A'1 Strip Pit spring discharge was within the range <br />observed during 1982 through 1986. Flow from this spring is <br />influenced by both snowmelt and ditch seepage associated with the <br />7 North Angle discharge. <br />• <br />• 8 <br />
