2.2.1.4 Bedrock Water Quality Water sampling and analysis are no longer required <br />from the bedrock monitoring holes. However, as required by DMG, prior to entering <br />Federal leases C-8424 and C-8425, one water quality sample was collected and analyzed <br />from each of the monitoring holes in federal leases C-8424 and C-8425. Such sampling <br />was limited to the middle (coal facie) zone. <br />The Deserado Mine First Annual Hydrology Report (December 1985) contains baseline <br />water quality data for the bedrock zones except for wells in federal leases C-8424 and C- <br />8425. Baseline water quality data for these wells are given in the Thirteenth Annual <br />Hydrology Report (January 1998). Water quality data for 32-7M was collected in 2001 <br />prior to mining it out and is included in Appendix C of the Seventeenth Annual Hydrology <br />Report (January 2002). Comparing the 2001 data to the 1997 data indicated only slight <br />changes with a general improvement in quality for most parameters of 32-7M. <br />2.2.1.5 Mine Water Balance Table 2-2 shows the water balance for the Deserado Mine. <br />No water has been pumped from underground workings since January 10, 1996. Electric <br />power to the pumps has been cut off due to the underground fire; the pumps have been <br />removed. During the 1996-1997 period, Deserado Mine started disposing the prep plant <br />thickener water in the mined out area of the D-Seam (the first longwall district). This water <br />would have been otherwise discharged through Pond PP-2. A description of how these <br />numbers are arrived at follows. <br /> <br />
