• These assumptions, however, do not hold true for Well WW14. Prior to <br />mining in the north area (November 1992), this well was almost always <br />dry (see the 1993 AHR for a complete listing of earlier water level <br />data). Since this particular portion of the Wadge seam was dry prior to <br />mining, spoils water will now contribute 1008 of the water present. <br />- Sage Creek Overburden. This unit exits between the Wadge and Wolf <br />Creek coal seam. Well WSOV29 was drilled in August 2001 in the II-W <br />South area. <br />- Sage Creek Coal. Well WSC29 was drilled ~in August 2001 in the I.I-W <br />South area. <br />- Wolf Creek Coal. Two wells monitors this coal seam. Well WWC4 exists <br />in the II-W South Expansion area. Monitoring at this well was resumed <br />in July 1997 after being discontinued in June 1985. This well, so far, <br />has not been impacted by mining. Well WWC24 was drilled in August 2001 <br />in the II-W South area. <br />- Wolf Creek Overburden/Underburden. Wells WWCOV29 (overburden) and <br />WWCU24 (underburden) were drilled in August 2001 in the II-W South area. <br />- Trout Creek Sandstone. Well WTC201 is used as the water supply well <br />for the mine facilities. It displays an increasing TDS trend. <br />Comparison of Ground Water Qualify 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. 91, March 1999). <br />Table 6 provides a comparison of ground water quality to agricultural <br />standards. This Paradox database generated table does not include the <br />units of concentration (mg/1 or ug/1) for each parameter. The units <br />used for each parameter are the same as those listed on the standards <br />table (Table 5) and are also the same as those used in the water quality <br />reports. The frequency column on Table 6 indicates the number of <br />9 <br />
