' 'Dissolved metals analyses for alluvial and groundwater During October 1984, the Taylor Draw Reservoir facilities were completed and the reservoir began filling with water. The area around the alluvial groundwater holes has become a shallow water mud flat area with the deposition of mud, silt and sand at high reservoir levels. As a result, alluvial groundwater monitoring holes Qal-1, Qal-2, Qal-3, Qal~ and Qal-6 have been destroyed and are no longer available for monitoring. Alluvial hole Qal-5 is still being monitored. ' During May 1987, longwall panel 1 was mined past the location of 2-12U. The location was subsided and the monitoring hole could no longer provide usable data. Accordingly, Western Fuels (now BME) submitted an application for a Technical Revision on 6/7/88 to eliminate groundwater monitoring at 2-12U. The Technical Revision was subsequently approved. ' As per the DMG permit requirement, water from the groundwater monitoring holes 29-4, 30-8, 31-7 and 33-8 in Leases C-8424 and C-8425 were sampled and analyzed during the 1996-1997 ' water year. Appendix I of the Thirteenth Annual Hydrology Report gives the analysis results. As 9
