~~ <br />:~~~ <br /> <br />Tom Gillis - 3 - April 4, 1985 <br />Surface Water Data <br />Surface water quality on Ward and Williams Creek is good, with both <br />tending to be sodium-calcium bicarbonate water, with some sulfate. In <br />general, trace metals concentrations are low or below detection limits. <br />2. SP-B sample results clearly reflect the effects of the refuse pile in <br />that it is also a calcium bicarbonate-sodium sulfate water. Although, <br />it does have higher pH values and lower concentrations of major ions. <br />Trace metals, however, only appear to be occasionally high in iron and <br />manganese. <br />Mine Water <br />1. The primary concern is for UG-5 and UG-6. UG-5 is of very poor quality <br />with TDS values sometimes in excess of 12,000. This is a neutral to <br />high pH calcium bicarbonate-sodium sulfate water. Trace metals are <br />occasionally high in iron and manganese. <br />2. UG-6, the mine discharge water, is of moderate quality with an average <br />pH of 8. TDS levels are generally 1200 or less but up to 2300. This <br />is also a calcium bicarbonate-sodium sulfate water. Trace elements are <br />generally low or below detection limits. <br />If you or the operator have any questions or comments please contact me. <br />PS/ljc <br />0158E <br />
