Modified after Mayo and Associates,1996a. <br />TU) suggests that the water is old. A74C age could not be determined for the UG-11E <br />water because the sample has been affected by CH4 gas (i.e., HCO3 S13C = +16.3 °~w). <br />However, other roof drip waters have negligible 3H contents and a mean 14C age in <br />excess of 20,000 years. The discharge temperature of UG-11E water, 22.8°C, is slightly <br />thermal, also suggesting the water up wells along the fault damage zone. For <br />comparison, roof drip waters have temperatures 6 to 12°C cooler. <br />Evaluation of Potential Groundwater Inflows 24 February 24, 2004 <br />Associated with E Seam Mining, <br />West Ells Mine, Somerset, Colorado <br />
