<br />pressurized by gases, so no water elevation measurements in the Rollins Sandstone can be <br />obtained. <br />Water in the Rollins Sandstone is confined to limited localized zones that aze fractured and/or <br />contained above the Rollins, as evidenced by water level measurements that are well above the <br />' top of the sandstone member. Water quality is poor, with high total dissolved solids as sodium <br />chloride. Inflow and recovery of the water level in the drill holes indicates very low <br />permeability and porosity of the sandstone. There has been some variability in the water levels <br />' measured in wells SC-1, SC-2 and TC-1, but there has been no appazent trend or indication of <br />impact. SC-2 could not be monitored in September and December possibly due to a neazby <br />' active landslide hazazd. No significant difference in the 2000 monitoring results from baseline <br />or historical measurements was noted. <br />' Monitoring of well SC-3 provides information on the water-bearing zone in the vicinity of the D- <br />Seam located some 200 feet above the B coal seam being mined in the Sanborn Creek mine. <br />There has been some variability of water level in this well, but shows no appazent trend or <br />' indication of impact. No significant difference in the 2000 monitoring results from baseline or <br />historical measurements was noted. <br />Monitoring well WSC DH12, a methane degasification drill hole for the abandoned Hawk's Nest <br />Mine, is monitored in June of each yeaz for field pazameters, and a sample is taken for analysis <br />of the full suite of groundwater quality pazameters. On June 20, 2000 the well was found to be <br />dry so no sample was taken. No significant difference in the 2000 monitoring results from <br />baseline or historical measurements was noted. <br />' Well TC-2 was completed in the North Fork alluvium to the east of Thompson Creek late in the <br />spring of 1997. No significant difference in the 2000 monitoring results from baseline or <br />historical measurements was noted. <br /> <br /> <br /> <br />t <br /> <br />1 <br />169 <br />
