Appendix I of the Thirteenth Annual Hydrology <br />Report provides the analytical results. Monitoring hole 32-7M was sampled prior to being <br />mined out in 2001 and 30-8M before it had a chance to drain after being completely mined <br />around in late 2006. Data is provided in Appendix C of the Seventeenth Annual Hydrology <br />Report for 32-7M and the Twenty Third Annual Hydrology Report, for 30-8M. <br />2.2 Summary and Analysis of Deserado Mine Hydrology Data <br />Data collected during this water year (October 1, 2008 to September 30, 2009) have been <br />summarized and compared with the data from the baseline hydrology inventory. Surface <br />water and ground water discussions are presented separately in the following sections. <br />4
