location (immediately below the 005 Poad dam), moaitorinq at this aprinq hoe bean <br />voluntarily reestablished in 1992. The SC plot indicates a nearly level trend. <br />Sprlaq 5.47 was first discovered by SCC personal is 1989 and was monitored first is Juna, <br />1990. It is a developed spring existing alongside the mine anirance haul road just to the <br />west of the Seneca II-97 Meteorological Station. It is not required by the hydrological <br />moaitorinq Program, monitoring 15 voluntary. Its EC Dlot indicates a recently decreasiaq <br />trend. <br />Sprlaq 5-48, a.k.a. the Flandar'e Sprlaq, was developed by SCC in the fall of 1992 Dar a <br />lead owner's agreement with Ralph Flanders, It is mot required by the hydrological <br />monitoring program, moaitorinq Se voluntary. The first lab sample was taken oa Jvne 27, <br />1994. The EC plot indicates a decreasiaq trend. <br />The hydrology monitoring program at the Seneca II-W Hine requires a spoil spring survey <br />every year after the spring snowpeck runoff. Ho spoil springs have been discovered. <br />• Compazisoa of Surface Water 4uality to Water IIse Standards. Water quality from all <br />stream, spring, and NPDES sites were compared against irrigation standards (Table 5, see <br />Ground 19ater section), and the comparison results are presented im Table 11 (Appendix A). <br />Standards that were exceeded are alwninum at [Ores si tea (due to clay sunerals is high TSS <br />samples), chlorides at one site, pH valves (between 6.50 to 8.67) at six sites, iron at <br />five sites, manganese at six sites, TDS at two sites, and sulfates at ten sites. Of sll <br />the surface water sites downstream of Seneca II~W, only Sites WSDS (Dry Creek) and WSSF3 <br />(Sage Creek) have their waters used for irrigation. Also, water from Site WSHF1 (lower <br />Hubberson Gulch) has the potential of being used far irrigation, although this has not <br />been developed as such. <br />Surface water quality data measured at all stream, spring, end NPDES sites were compared <br />with the standards list for livestock drinking water (Table 6, see Ground Water section) <br />and are presented in Table 12 (Appendix A). Standards that were exceeded are aluminum at <br />three sites and pH values at six sites. <br />• SurEnce Water Summary. The limited amount of mining that bas occurred at Ibis mime <br />Imialnq began in 1990) has had little effect oa surface water quality. All stream sites <br />
