In the area surrounding Seneca II, grounQ water is not being pvaiped for irrigation or livestock vaterinq purposes. The above discussion is provided only co serve as a • comparative basis to ludge ground eater quality. Domestic yells that provide drinking eater for local residents are not from aquifers ia~acted by mining. Mining at Seneca II is not believed to be causing the degradation of any monitored aquifer. Surface Water Table 9 lists pertinent information on all NPDSS, stream, and spring monitoring sites at the 9eneea II Mine. A complete description of the surface vatel monitoring program may be found on Pages 7-161 to 7-169 of the 9eneea II permit Application Package. NFDES Discharge Points 002, 003, 004, and 008 are monitored weekly. Stream Monitoring Sites 1, 2, 5, and 6 are monitored monthly from March through October. All of the NFDES and Stream Monitoring Sites 1, 2, 5, and 6 are sampled three times a year for water quality. The first sample of the year is collected prior to peak rnnoff (March): the second sample is collected after peak runoff (Hay or June): and the third sample is collected during base floe conditions (September). Samples collected at all these sites were analyzed using the surface water long list, Table 10 (Appendix A). The two stream monitors on Fish Creek (Sites 11 and 13) and the two on Fish Creek tributaries (91tes 10 and 12) are monitored • , monthly from May through September. When no floe is observed at the Cow Caaq~ or Hond Creek sites (Shea 11 and 13), the two Flsh Creek sites (Sites 10 and 12) are not monitored. This year, monitoring occurred at these four sites in May, June, and July. At the Seneca II Hine, there are four springs (native) that are sampled annually (in the spring). Ten spoil springs are monitored in the spring season each year after the ground had dried from snovmelt. In addition, Spoils b~zing RS was monitored for the long list concurrently with Site 6, and vas monitored biweekly and concurrently with NPDE9 004 for flow anQ Eield parameters from Harch to June. Surface eater quality data are presented in Appendix S. Data for each site begins with a floe hydrograph of all historic data (plus an annual hydrograph for NPDES sites), followed by a listing of individual eater quality and quantity data for the current eater year, a TD9 regression plot using the LOWESS method (see Oround Water puality section), and then a listing of historic percent millequivalent values for ma]or ions and TDS values. Crest stage gage rating curves are presented in Appendix F. NFDES discharge monitoring reports (DMRS) are presented in Appendix G. Lab aav~les are hanQled identically to procedures • d19cu99ed previously in the Ground Water puallty section. For the sake of brevity, B
