i <br />- Wadge Overburden. Well YOV28 monitors overburden water quality in the <br />Annl nd Draw basin. It displayed an increasing TDS trend until 1998, but <br />nowldisplays a decreasing trend. Wells YOV29 and 30 exist in the Sage <br />I <br />Creek basin. Well YOV29, prior to 1998, never had enough water for <br />sampling. However, subsequent water levels in this well had increased, <br />and water samples were collected in 1998 and 1999. In May 2000 this <br />well went dry and continues to be dxy. Well YOV30 displays a decreasing <br />TDS. trend. <br />- Wadge Coal. Well YW28 monitors coal seam water quality in the Armand <br />Draw basin. It displays a level TDS trend. Wells YW29 and 30 exist in <br />the. Sage Creek basin. Well YW29 displays a. level TDS trend. Well YW30 <br />displays a level TDS trend. <br />- Wadge Underburden. Well YWU28 monitors Underburden water quality in <br />the Armand Draw basin. It displays a level TDS trend. Wells YWU29 and <br />30 exist in the Sage Creek basin. Well YWU29 has recently displayed a <br />slightly increasing TDS trend. Well YWU30 displays a decreasing TDS <br />trend. <br />- Wolf Creek Coal and Underburden. Well YWC31 monitors the Wolf Creek <br />coal water quality in the Sage Creek basin. This well displays a <br />decreasing TDS trend. No mining of this seam has occurred. Well YWCU31 <br />monitors the Wolf Creek underburden water quality in the Sage Creek <br />basin. This well is normally dry. <br />rison of Ground Water Ouality to Water Use Standards. SCC has <br />compiled a list of ground water standards for agricultural uses iTable <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 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 /> <br /> <br />• I <br />6 <br />
