All bedrock aquifers affected by mining have been determined <br />to have transmissivities less than 100 ft2/day, which would also - <br />preclude their use for yielding sufficient water for irrigation, or even <br />livestock. ., - <br />I <br />Surface Water <br />i <br />A- summary'of surface water, monitoring sites and sampling history is j <br /> <br />presented in Table 7. At Seneca SI-W,' all stream sites (unless <br />otherwise noted) are monitored monthly (excluding, November to .February) ~ ~ - <br />for (flow and field parameters (flow, temperature, pH, and electrical.. .. . <br />conductivity). NPDES Discharge Points, 015 and 016 are monitored weekly <br /> } <br />..(whe'n accessible by truck) far flow and pHl A11 five NPDES sites are _ <br />moniJtored monthly for NPDES parameters and field parameters. Samples <br />obtmined at all NPDES and stream sites are analyzed for the surface <br />watelr parameter list, Table 6, during April, June, and September. <br />Springs are monitored semiannually (once in April-June, then again in <br />September-November) for flow, field parameters, and, if flow exceeds. <br />five gpm, the surface water parameter list. Monitoring frequencies for <br />surface water sites may be found in Appendix 15-3a of the Seneca II-W <br />PAP: <br />All ,surface water data is found in Appendix E. Data for each site in <br />Appendix E begins with a flow hydrograph of all historic data (plus an <br />i <br />annual hydrograph for NPDES sites), followed by a listing of individual <br />water quality and quantity data for the current water year. After the <br />water quality report is a statistics report representing baseline (i.e., <br />premising) data for each site downstream of mining (when available}. On <br />this statistics report, "censored data" refers to analytical values that <br />were below the detection limit, which were censored from the <br />min/max/mean calculations. The time frame for baseline conditions is <br />listed under "conditions specified" at the bottom of each page, This is <br />12 <br />
