all Wadge coal wells at Seneca II -W. 2) Aquifer characteristics were an <br />average of all Wadge coal wells at Seneca II -W. 3) The Wadge coal seam <br />was saturated for its entire thickness (11.8 feet) . These assumptions, <br />however, do not hold true for Well WW14. Prior to mining in the north <br />area (November 1992), this well was almost always dry (see the 1993 AHR <br />for a complete listing of earlier water level data). Since this <br />particular portion of the Wadge seam was dry prior to mining, spoils <br />water will now contribute much of the water present. Also, the water <br />level this year, 7.18 feet, indicates that additional strata are being <br />saturated, which may also explain the elevated TDS value. <br />Agricultural ground water standards were exceeded this year at certain <br />monitoring wells. Tab 7 of the Seneca II -W PAP contains a section that <br />discusses the suitability of using water from the various aquifers <br />monitored at the Seneca II -W Mine for irrigation or livestock watering. <br />The discussion mentions that all aquifers prior to mining at the Seneca <br />II -W Mine have exhibited several parameter concentrations in excess of <br />both irrigation and livestock standards compared, rendering them <br />questionable regarding their suitability for either irrigation or <br />livestock. 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 />Surface Water <br />A summary of surface water monitoring sites and sampling history is <br />presented in Table 8. Tables 9a and 9b show the new (2010) surface water <br />parameter lists. At Seneca II -W, all stream sites (unless otherwise <br />noted) are monitored for flow and field parameters (flow, temperature, <br />pH, and electrical conductivity) and one of the new surface water <br />parameter lists during spring runoff and summer baseflow. All six NPDES <br />sites are monitored monthly for NPDES parameters and field parameters. <br />Springs are monitored annually (May -July) for flow, field parameters, <br />and, if flow exceeds five gpm (0.011 cfs), one of the new surface water <br />10 <br />
