The water level in Hole 30-8M remained relatively stable with a drop of 0.7 feet. This well <br />is located in a pillar next to the start line for LWB-8. This pillar was developed in <br />September 2006. A substantial decrease in water level was noted following the <br />development work. The change noted in 2009 is not considered significant. <br />Hole 31-7M decreased in water level 0.5 feet. This well is up gradient from mining <br />activity and the water level fluctuation is minimal. <br />33-8M experienced a similar drop in water level (1.1 feet) as 33-8U probably due to the <br />influence of mining in longwall panel LWB-6 and LWB-7. <br />The hydrographs of the "lower sandstone facies" are designated by the letter "L" following <br />the hole number. <br />Hole 2-17L showed a rise of 14.9 feet from the prior year. <br />Hole 33-81- showed a 2.0 foot decrease in the depth to water. This response is similar to <br />but more pronounced as in the adjacent 33-8U and M holes. <br />Hole 4-20L continued a slow but steady decline of 2.1 feet from the prior year. This <br />decline can be attributed to its close proximity to mine workings in the abandoned D- <br />seam. <br />Monitoring hole 22-21- was completed in October 2005 for monitoring future mining <br />expansion. This hole recorded a 3.4 foot drop in the water table over the prior year. <br />From the baseline data, all three zones should be classified as "aquitards" in that they will <br />yield water but at very slow rates. Mining in the B Seam so far has encountered only <br />small flows of water and the mine is essentially dry. Typical inflows are in the order of 1 to <br />8 gpm with occasional short term increases when localized perched water tables are <br />encountered. Water leaking out of caved areas is routed to the sumps at the end of <br />gateroads. No underground water has been pumped out of the mine since the January <br />31, 1996 underground fire. Currently, excess water is pumped from the B-seam to the <br />abandoned D-seam for storage. <br />2.2.1.4 Bedrock Water Quality Water sampling and analysis are no longer required <br />from most of the bedrock monitoring holes. However, as required by DRMS, prior to <br />entering Federal leases C-8424 and C-8425, one water quality sample was collected and <br />analyzed from each of the monitoring holes in federal leases C-8424 and C-8425. Such <br />sampling was limited to the middle (coal facie) zone. <br />7
