West Elk Mine 2013 Annual Hydrology Report 32 <br />3.2.4.6 Spring J -10 <br />Spring J -10 is located on the south side of the Dry Fork stream adjacent to the Minnesota <br />Reservoir flume. This spring is located west of the SOD mine panels area. The source of <br />this spring appears to issue from alluvium. This spring appears to be perennially wet, but <br />flows do not exceed a trickle. Baseline monitoring at this spring was completed in WY <br />2011, and routine hydrologic monitoring (three times per year) commenced in WY 2012. <br />3.3 Groundwater Monitoring Program <br />In WY 2013, a total of 14 wells were monitored as part of the MCC groundwater <br />monitoring program (Tables 6 and 7). This number does not include 14 wells (SOM -21-1, <br />SOM -16 -1-1, 96 -27 -1, SO.W -1, SOM- 45 -1-11, SOM -3E, SOM 13, SOM 129 -H, SOM -23- <br />H-1, SOM- 23 -H -2, SOM- 23 -H -3, SOM -313, 96 -2 -2, and SOM- 23 -1-1-4) that have been <br />irreparably damaged, blocked, or have collapsed casing. Well SOM- 23 -H -4 was <br />monitored in May 2013, but the casing was found to have collapsed; therefore, <br />subsequent monitoring in 2013 and beyond has been abandoned. <br />The groundwater monitoring wells are divided into the following 6 categories for <br />discussion purposes: <br />• Facility Area Wells and Alluvial Wells <br />• Wells completed in the Barren Member above the F -seam <br />• Wells completed in the F -seam <br />• Wells completed in the E -seam <br />• Wells completed above the E -seam <br />• Wells completed in the B -seam <br />The locations of the groundwater monitoring wells are shown on Map 2. A summary of <br />the groundwater monitoring well characteristics is presented in Table 6. A summary of <br />the groundwater monitoring program including mining areas monitored is presented in <br />Table 7. The water quality data for the period of record for all of the groundwater <br />monitoring wells are summarized in Appendix G. <br />June 2014 HydroGeo, Inc. <br />
