Refuse Area Holes <br />Hole M-7, located at the head of the draw being used for coal refuse <br />disposal, was tested by slug injection. After injecting 8 gallons, <br />the residual head was monitored. The straight-line portion of the <br />data plot yields a very low value of 3 gpd per foot (Exhibit 8). <br />Hole D-lA, located on the berm at the bottom of the refuse disposal <br />draw, was also tested by slug injection. This test yields a T value <br />of 31 gpd per foot (Exhibit 9). <br />• <br />• <br />
