• HG-2 <br />(East Well) <br />1. Elevation at the top of the casing: <br />Lollar Elevation 7,533.2 <br />Ground Elevation 7,531.1 <br />Northing 377,508.9 <br />Fasting 1,500,091.2 <br />2. Total depth of each well: <br />HG-2 was drilled and completed to a depth of 270 feet, which is 11.5 <br />feet below the base of Seam 5. <br />3. Locations and thickness of water bearing zones within the wells: <br />HG-2 encountered the first water zone at a depth of 60 feet. The flow <br />was on the order of 2 to 3 gpm from a shaley siltstone. This flow, <br />similar to the first flow encountered in HG-1, is believed to be the <br />result of secondary porosity caused by fracturing. Additional flows <br />on the order of 1 to 2 gpm were encountered in a sandstone between 138 <br />feet and 145 feet and in the coal seams. <br />4. Stratigraphy associated with the wells, including lithologies and <br />• thickness of units: <br />As stated above, geophysical logs are provided for your convenience in <br />Exhibit 5. <br />5. Well completion logs: <br />HG-2 was completed as shown in Figure 2.05.6-1 of the Permit. The <br />only exception is that the well was completed to a depth of 270 feet <br />versus 265 feet shown in Figure 2.05.6-1. <br />In addition to the above information, HG-1 and HG-2 are plotted <br />on the Final Reclamation Map included in this report. <br />On November 5, 1987, both wells were sampled for quality, water <br />level, and the composite flow into the well. Field analysis of pH and <br />conductivities indicate the completion method for the new wells was <br />acceptable and the previous assumption that the old wells were contaminated <br />by grout is valid. Following are the field results for the sampling on <br />November 5th. <br />HG-1 HG-2 <br />Depth to water (ft.) 13.6 77.1 <br />pH 7.3 7.3 <br />Conductivity (UMNOS/CM) 1,310 1,150 <br />.
