Carter March 12, 1998 <br />Re: Response to Susan Burgmaler's comments on the 1996 Annual Hydrologic Report <br />level was measured in October 1997 at elevation 6054. Regardless of what caused the various changes <br />in elevation of water in the abandoned Somerset Mme as the worlangs fitled with water over time, it <br />appears the Somerset Mme contains water at an elevation above the elevation of the contact between <br />the B-Seam and the alluvium of the North Fork of the Gunnison River. <br />Graph 4.

Review of water quality from the samples <br />of B-6 and H-] 0, along with monitoring data from monitoring well SC-3, indicate conditions for <br />groundwater associated with coal seams in this area, medium to high total dissolved solids. <br />21 <br />1 <br />
