<br /> <br /> <br /> <br /> <br /> <br /> <br />~~ <br /> <br /> <br /> <br /> <br />a part of the mid-term review technical revision (TR48), BME requested that DMG approve <br />discontinuing the monitoring of the following wells: <br />TW2-7U It has remained dry <br />TW2-7L It has remained dry <br />2-7U It has remained dry <br />2-7M It has remained dry <br />2-7L It has remained dry <br />35-4U tt has remained dry <br />35.4E It has remained dry <br />RM-1 It has remained dry <br />35-4M This hole is venting methane; presumed dry <br />DMG approved BME's application on November 10, 1998. <br />2.2 Summary and Analysis of Deserado Mine Hydrology Data <br />Data collected during this water year (October 1, 1997 to September 30, 1998) 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 Monitorinn Data Groundwater monitoring data consists of water levels <br />measurements. Tabulation of the raw data is included in Appendix C. Hydrographs for the 26 <br />stations (monitor holes) from which water level data were collected are included in Appendix D. <br />Table 2-2 is a statistical summary of the water level data. <br />2.2.1.1 Alluvial Water Level Data Water level data have been collected from the one <br />remaining original alluvial aquifer monitoring hole (QAL-5) and the Refuse Disposal Area alluvial <br />monitoring hale (RM-1). Five other alluvial monitoring holes were inundated by Kenney <br />' Reservoir. A hydrograph of the water level data for QAL-5 is contained in Appendix E. The <br />statistical summary of the water level data for QAL-5 is also included in Table 2-2. No water <br />was ever detected in RM-1. The locations of these monitoring holes are shown on Plate 1 in <br />the pocket of this report. The Qal-5 hydrograph shows a significant increase in the alluvial <br />water level of the White River since the second half of 1985. This rise was due to the filling of <br />' Kenney Reservoir. Since that time, fluctuations reflect the seasonal rise and fall of the reservoir <br />level. <br />' 2.2.1.2 Alluvial Water Quality Data The water quality data for QAL-5 is contained in Appendix <br />E. The statistical summary of the data is also contained in Appendix E. A statistical summary <br />' of depths for l]AL-5 is also included in Table 2-2. The fifth annual hydrology report noted that <br />s <br />1 <br />
