Hole 33-8L experienced a 5.5 foot drop in the depth to water. As with 33-8U and 33-8M this change can be related to the longwall mining of panel LWB-6. All other lower facies holes experience what is considered normal seasonal fluctuations of water level. From the baseline data, all three zones should be classified as "aquitards" in that they will yield water but at very slow rates. Mining in the B Seam so far has encountered only small flows of water and the mine is essentially dry. Typical inflows are in the order of 6 to 8 gpm with occasional short term increases when localized perched water tables are encountered. Previously, water leaking out of caved areas was routed to the sumps at the end of gateroads. No underground water has been pumped out of the mine since the January 31, 1996 underground fire. Currently, excess water is pumped from the B-seam to the abandoned D-seam for storage. ' 2.2.1.4 Bedrock Water Quality Water sampling and analysis are no longer required from the bedrock monitoring holes. However, as required by DMG, prior to entering ' Federal leases C-8424 and C-8425, one water quality sample was collected and analyzed from each of the monitoring holes in federal leases C-8424 and C-8425. Such sampling was limited to the middle (coal facie) zone. The Deserado Mine First Annual Hydrology Report (December 1985) contains baseline water quality data for the bedrock zones except for wells in federal leases C-8424 and C- 8425. Baseline water quality data for these wells are given in the Thirteenth Annual Hydrology Report (January 1998). Water quality data for 32-7M was collected in 2001 prior to mining it out and is included in Appendix C of the Seventeenth Annual Hydrology Report (January 2002). Comparing the 2001 data to the 1997 data indicated only slight changes with a general improvement in quality for most parameters of 32-7M. 2.2.1.5 Mine Water Balance Table 2-2 shows the water balance for the Deserado Mine. No water has been pumped from underground workings since January 10, 1996. Electric power to the pumps has been cut off due to the underground fire; the pumps have been removed. During the 1996-1997 period, Deserado Mine started disposing the prep plant thickener water in the mined out area of the D-Seam (the first longwall district). This water would have been otherwise discharged through Pond PP-2. A description of how these numbers are arrived at follows.
