<br />-6- <br /> <br />Whether the wells remain in existence or were sealed upon completion of <br />testing is not addressed in the permit application. <br />Bedrock water quality is generally good upslope and degrades in a downslope <br />direction. TDS levels experience rapid rises downslope (575 mg/1 to 3,017 <br />mg/1). PBd+I explains this degradation by assuming most of the upslope water is <br />a result of recharge through deep percolation. The increased levels occur as <br />the water moves downdip through the bedrock aquifer. This drastic change is <br />not noted at other mines in the area but may be a result of extensive rock <br />fracturing related to folding in the area or to blasting as apart of previous <br />mining operations. <br />
