permit area. It displays an overall stable TDS trend, although values <br />have increased since October 2003. <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 />historically displayed an increasing TDS trend (SF 0.5), although <br />recently it has stabilized. Well 8P1 is located below a reclaimed <br />portion of the Wadge pit in the southwest corner of the permit area. <br />The TDS values for this well has stabilized. Well it is located just <br />west of the PeaCoCo Pond, below a reclaimed portion of the Wadge pit. <br />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 very slightly increasing TDS trend <br />(42 mg/1 over 24 years). <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 overall increasing <br />TDS trend, however, TDS values peaked in 1998. <br />Well 61 is located in the southwest portion of the permit area. It <br />displays a decreasing TDS trend. Well 62 is located above NPDES 004. <br />It displays an increasing TDS trend. <br />Comparison of Ground Water Quality to Water Use Standards. SCC has <br />compiled a list of ground water standards for agricultural uses (Table <br />5). This list is composed of Colorado Department of Health ground water <br />standards (CDOH, Reg. 41, March 1999). <br />Table 6 provides a comparison of ground water quality data this year to <br />agricultural standards. This Paradox database generated table does not <br />include the units of concentration (mg/1 or ug/1) for each parameter, <br />The units used for each parameter are the same as those listed on the <br />8 <br />
