• 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 towards the azea associated with the Sanbom Creek Mine. <br />SC-3 Well - B-Seam Coal -Sanborn Creek Mine <br />Monitor well SC-3 is located east of the Sanbom Creek reclaimed mine portal area along the <br />entrance to the pre-existing ranch road to Coa] Gulch. <br />Monitoring well SC-3 was completed in the B Seam coal.=allyIonitoring data were collected from <br />well SC-3 prior to any substantial mining in the B-Seam of the Sanbom Creek Mine. The SC-3 <br />well is up-gradient relative to the B seam underground mining activities but down-gradient from <br />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. Once <br />a smaller diameter bailer was obtained very minimal water was available and a sample was <br />obtained on June 22, 2004. The lack of water in the well during a drought period and the poor <br />water quality suggests there is little transmissivity and connection between the North Fork of the <br />Gunnison River and the B seam 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 ua-gradient of the Sanborn creek mining area, their utility towards the monitoring <br />• of the Sanborn creek mine itself appears somewhat limited. <br />• <br />13 <br />
