TDS was due to the accumulation of water in the North Angle Sump location which was <br />able to equilibrate with oxidized rock within old workings and rubbelized rock within <br />subsidence panels. The maximum concentrations of 1474 mg/I probably represents this <br />equilibrium concentration. Flow from the #1 Strip Pit spring discharge was within the <br />range observed during 1982 through 1986. Flow from this spring is influenced by both <br />snowmelt and ditch seepage associated with the 7 North Angle discharge. Flows from <br />the 5 Mine workings were, of course, notably lower than previous years. <br />i <br />w c-e,-0u ,9eaa,R Page 13 <br />
