I ~ ground water quality. Domestic wells that provide drinking water for <br />local residents are not from aquifers impacted by mining. <br />Surface Water <br />Table 7 lists pertinent information on all NPDES, stream, and spring <br />monitoring sites at the Seneca II Mine. A complete description of the <br />surface water monitoring program may be found on Pages 7-336 to 7-355 of <br />the Seneca II PAP, and is summarized on pages 7-349/350. NPDES <br />Discharge Point 003 is monitored weekly for field parameters (flow, <br />temperature, pH, and electrical conductivity). Points 002, 004 and 008 <br />are monitored monthly for field parameters. All four NPDES sites are <br />monitored monthly for NPDES parameters, Stream Monitoring Sites SSG1 <br />and SSG2 are monitored for field parameters monthly from March through <br />October. Both of these sites, as well as Sites SSG3 and SSLGS, are <br />sampled three times a year for full-suite water quality. The first <br />sample of the year is collected during the spring runoff (March or <br />• April), the second sample is collected after the spring runoff (May or <br />June), and the third sample is collected during base flow conditions <br />(September). Full-suite lab samples collected at all these sites were <br />analyzed using the surface water long list, Table 8. The two stream <br />sites on Fish Creek (Sites SSFll and 13), and the two on Fish Creek <br />tributaries (Sites SSC10 and SSB12), are monitored monthly from May <br />through September for field parameters and full-suite lab samples. When <br />no flow is observed at both the Cow Camp or Bond Creek sites (Sites 10 <br />and 12), the two Fish Creek sites (Sites 11 and 13) are not monitored. <br />At the Seneca II Mine, there are eight spoil springs are monitored for <br />field parameters and full-suite lab samples in the spring and fall <br />seasons. In addition, Spoils Spring 1 was sampled for a full-suite lab <br />samples concurrently with NPDES 004, and was monitored monthly and <br />concurrently with NPDES 004 for field parameters from March to October. <br />Surface water quality data are presented in Appendix D. Data for each <br />. site begins with a flow hydrograph of all historic data (plus an annual <br />hydrograph for NPDES sites), followed by a listing of individual water <br />
