• The limited water quantity and poor water quality suggests there is limited transmissivity <br />between the North Fork of the Gunnison River alluvium through the Rollins sandstone down- <br />gradient towazds the area associated with the Sanborn Creek Mine. <br />SC-3 Well - B-Seam Coal -Sanborn Creek Mine <br />Monitor well SC-3 is located east of the Sanborn Creek reclaimed mine portal azea along the <br />entrance to the pre-existing ranch road to Coal Gulch. <br />Monitoring well SC-3 was completed into the B Seam coal. Monitoring data were collected <br />from well SC-3 prior to any substantial mining in the B-Seam of the Sanborn Creek Mine. The <br />SC-3 well is up-gradient relative to the B seam underground mining activities but down-gradient <br />from the North Fork of the Gunnison River <br />The plastic pipe casing is squeezed at the 20 foot level making it difficult to lower a bailer. <br />Using a smaller diameter bailer we have found very minimal water available in the well. In fact <br />there aze times when the initial bailing of the well to remove one volume effectively drains the <br />available water. The lack of water in the well and the poor water quality suggests there is little <br />transmissivity and connection between the North Fork of the Gunnison River and the B seam <br />coal at this particular vicinity of the mine. <br />As the of SC-1 and SC-3 wells serve to monitor only the Rollins sandstone and B-seam coal <br />. respectively up- radient of the Sanbom creek mining area, their utility towazds the monitoring <br />of the Sanborn creek mine itself remains somewhat limited. <br /> <br />15 <br />
