Water levels are <br />' measured quarterly in the sixteen groundwater monitoring holes. The water level is measured <br />monthly in Oi4L-5, and samples collected quarterly to analyze for the twenty two water quality <br />parameters listed in Table 2-1. <br />1 The alluvial monitoring hole, RM-1, was drilled east (downsVeam) of the pond for Refuse Disposal <br />Area 2/3 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 tacitities 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 />r <br />
