Its EC plot indicates a decreasing trend. <br />The hydrology monitoring program at the Seneca II-W Mine requires a <br />spoil spring survey every year after the spring snowpack runoff. Spoil <br />Spring 1 (WSSPGI, not to be confused with WSPG1), was discovered in 1998 <br />above the NPDES 005 pond (D pit area). It exists approximately 800 feet <br />southeast of Well GW-52W-19W. This year, low flow was observed in June .. <br />and no flow in September. This is a temporary site that was regraded in <br />the winter of 2001/02. <br />Spoil Spring 2 (WSSPG2) was discovered in June 1999. It is located in <br />the main stream channel adjacent to Spring S-6. <br />Spoil Spring 3 (WSSPG3) was discovered in September 1999. It is located <br />immediately to the east of Pond 006. <br />• Comparison of Surface Water Quality to Water Use Standards. SCC has <br /> compiled a list of surface water standards for agricultural uses (Table <br /> 9). This list is composed of CDOH surface water agricultural' use <br /> standards (CDOH, Reg. 31, March 1999). <br />Table 10 provides a comparison of surface 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 9) and are also the same as those used in the water quality <br />reports. The frequency column on Table 10 indicates the number of <br />exceedences out of the total number of samples (i.e., 1/2 indicates one <br />exceedence out of two samples), Below is a summary of standards that <br />were exceeded. Given in parenthesis is the source and use of each <br />standard. Although the CDOH does not indicate between livestock and <br />irrigation uses in their surface water agricultural standards, they have <br />done so in their similar ground water agricultural standards (see Table <br />• 5). For the sake of discussion, SCC chooses to use those ground water <br />use standards classifications (livestock or irrigation) for surface <br />19 <br />
