Appendix I of the Thirteenth Annual Hydrology Report provides the analytical <br />results. Monitoring hole 32-7M was sampled prior to being mined out in 2001. Data is provided <br />' in Appendix C of the Seventeenth Annual Hydrology Report. <br />' 2.2 Summary and Analysis of Deserado Mine Hydrology Data <br />Data collected during this water year (October 1, 2000 to September 30, 2001) have been <br />' summarized and compared with the data from the baseline hydrology inventory. Surface water <br />and ground water discussions are presented separately in the following sections. <br />' 2.2.1 Ground Water Monitoring Data Groundwater monitoring data consists of water levels <br />measurements. Tabulation of the data is included in Appendix C. Hydrographs for the 16 <br />' stations (monitor holes) from which water level data were collected are included in Appendix D. <br /> <br />i~ <br />
