These lists are compoead <br />mostly of Colorado Department of Health (ODOR) standards, although other agencies' <br />stmdarda have beta used if they are more stringent or if the ODOR Las no standard for a <br />particular parameter. Sae SCC's Yoast Mine Permit Apylication, Tablas 7-21 and 7-23, for <br />e more detailed explanation of these standards. <br />Table 7 provides a comparison of ground water quality to irrigation standards. standards <br />that were exceeded during this reporting period aza iron 11 well), manganese (3 wells), <br />total dissolved solids (TDS, 1 well), and sulfates f9 wells). Ia addition, one well had a <br />cadmium value below the detection lrmrt that in turn was higher than the standard. <br />Table a provides a comparison of ground water quality to livestock standards. No <br />atandarde were exceeded during this reporting period. <br />SuIfflca Water <br />Required surface water sites are monr to red monthly (March to October) for flow and field <br />parameters (p R, temperature, and electrical conductivity [EC]). Samp'_es obtained at these <br />sites are analyzed for the surface water parameter lrst. Table 9, during April, May or <br />June, and September. A summary of surface water sites is Drovided is Table 10. The <br />current surface water and spring monitoring program is prey anted in Table 15.9 of the <br />Yoast Mine PAP. <br />All surface water date collected durino thrs reporting period are provided in Appendix D. <br />Included in this appendix and the following discussion are data from Bites no longer part <br />of the required monitoring program. Data ~yxovided for stream sites are a water quality <br />report, remarks (if present), and a surface water hydrograph (except for site Y552). Also <br />included (for al l required monitoring sites and certain nonrequized sites) are TDS plots <br />using the IAWESS method and TDS/millieyvivalent tables (see preceding Ground Water Quality <br />4 <br />
