• EXHIBIT 19 <br />AQUIFER TEST DATA <br />Aquifer characteristics have been determined at several locations in <br />the permit area by pump tests. The aquifer tests were conducted by sev- <br />eral private and government agencies. Data collected in the tests are <br />presented in this Exhibit as Table 1, Aquifer Characteristics. <br />Four aquifer tests have been conducted in the permit area to date. <br />These include tests of the following aquifers: 1) the Foidel Creek al- <br />luvium at well 08-FM-6 by the U.S. Geologic Survey; 2) the overburden <br />above the Wadge seam at well 08-FM-S by the U.S. Geologic Survey; 3) the <br />Wadge seam and overburden at Well 08-77-58 by Amuedo and Ivey, consultant <br />• geologists; and 4) the Wadge seam and overburden at Well 08-79-6 by <br />Colorado Yampa Coal Company. <br />The first test, performed by the U.S. Geologic Survey on October 15, <br />1975, was a drawdown test of the alluvium of Foidel Creek. According to <br />the log of well FM-6 presented in Exhibit 1, Drill Hole Logs, the allu- <br />vium produces water from a layer of sand and gravel from 15 to 20 feet. <br />Drawdown was measured during a constant pumping rate of 6.3 gallons per <br />minute. Drawdown vs, time is plotted in Figure 1, Well OS-FM-6, of this <br />exhibit. Transmissivity was computed using the straight-line method of <br />Stallman (Lohman, 1972), equalling 108.7 gpd/ft. Permeability was com- <br />puted by dividing the transmissivity by the saturated thickness, equal- <br />ling 21.7 gpd/ft2. These values are believed to be representative of the <br />• alluvial sand and gravel deposits in the permit area. <br />
