a 1990 to 2200 umhos/cm in 1997. Future data should be reviewed to verify whether this <br />apparent trend continues. Downstream alluvial wells do not reflect significant increases <br />in EC levels. <br />Surface water sites indicate a normal seasonal vaziation with regazd to flow. Most sites <br />indicate a flat trend with regazd to TDS or EC. However, site 1005 had 3 of 4 TDS <br />measurements return values equal to, or in excess of, 500 mg/l. Previously, all but one <br />historic measurement of TDS had been below 500 mg/l. Future monitoring should <br />determine whether this trend continues at this important site. <br />Pond and spoil spring monitoring continues and 1997 values show no indication of <br />degradation over previously reported values. <br />The mine inflow map, referred to in the text as Figure 118 was not labeled as such. Some <br />totalization of inflows should be done in future reports and compared to mine dischazge <br />or mine usage. <br />Overall, mining at the Foidel Creek mine has no impact beyond that predicted in the PHC <br />and has little effect of the surrounding hydrologic regime. <br />M:\coal\kag\tcc97atu <br />
