stable. Well 69, located below 46, overall displays a decreasing TDS <br />trend, although values have increased since May 2002. <br />Well 66, completed in the Bond Creek alluvium (below NPDES 008), was <br />drilled along with Well 69 (see above) in 1988. It displays a slightly <br />increasing TDS trend, <br />- Wadge Overburden. Well 42, located in the south central part of the <br />permit area, usually does not have enough water in its casing to sample, <br />as was the case this year. Milliequivalent data and the TDS plot from <br />previous samples have been included in Appendix C, <br />- Wadge Coal. Two wells are used to monitor the water quality of this <br />seam. Well 17 is located just west of NPDES 002. It displays an <br />increasing TDS trend. Well 19 is located in the southwest part of the <br />permit area. It displays a decreasing TDS trend. <br />- Wolf Creek Overburden/Wadge Underburden. Three wells are used to <br />monitor this stratum. Well 7 is located below the Wolf Creek pit. It <br />displays an increasing TDS trend, although recently it has stabilized. <br />Well BP1 is located below a reclaimed portion of the Wadge pit in the <br />southwest corner of the permit area. The TDS values for this well has <br />stabilized. Well 11 is located just west of the PeaCoCo Pond, below a <br />reclaimed portion of the Wadge pit. It displays a decreasing TDS trend. <br />- Trout Creek Sandstone. Well 5 is used as the potable water supply for <br />the Seneca II Mine. It displays a stable TDS trend. <br />- Spoils. Three wells monitor the spoils above NPDES 002. Well 25, the <br />upper well, does not display a distinct TDS trend. There was not enough <br />water in this well to sample since May 1997. Well 26, the middle well, <br />displayed an increasing TDS trend until 1990/1991, but has decreased <br />since then. Well 27, the bottom well, displays an increasing TDS trend <br />with some recent stabilization. <br />CJ <br />S <br />
