Water levels are <br />measured quarterly in the fifteen groundwater monitoring holes. The water level is measured <br />' monthly in OAL-5, and samples collected quarterly to analyze for the twenty lwo water quality <br />parameters listed in Table 2-1. <br />The alluvial monitoring hole, RM-1, was drilled east (downstream) of the pond for Refuse Disposal <br />Area 213 on September 28, 1989. The location of this hole is shown on Plate 1. This monitoring <br />hole was drilled to fulfill a requirement of the mine permit. RM-1 was drilled to bedrock at a depth <br />of 32 feet. No water was encountered during drilling. The hole was drilled with seven-inch hollow <br />flight augers and cased with perforated two-inch PVC pipe. The hole is monitored on a monthly <br />' basis. No water has been detected in RM-1 to date. If detected, the water level will be measured <br />and samples collected quarterly to be analyzed for the parameters listed in Table 2-1. <br />During October 1984, the Taylor Draw Reservoir facilities were completed and the reservoir began <br />filling with water. The area around the alluvial groundwater holes has become a shallow water mud <br />' 4 <br />1 <br />
