except in outcrop areas, although storage coefficient values <br />for the Wadge Coal and Wadge Overburden indicate that these <br />• aquifers are semi-confined or unconfined in some areas. <br />Alluvial aquifer transmissivity values range from 5.6 to 439.0 <br />ftz/day at the Seneca II Mine, and hydraulic conductivities <br />range from 0.5 to 62.7 ft/day. Most alluvial aquifer <br />transmissivity and hydraulic conductivity values are less than <br />40 ftz/day and 8 ft/day, respectively. Only one alluvial <br />aquifer test has been conducted at the Seneca II-W Mine; this <br />test yields a transmissivity of 1.4 ftz/day and a hydraulic <br />conductivity of 0.02 ft/day, lower values than found at the <br />Seneca II leasehold. <br />Three aquifer tests of the Wadge Overburden conducted at the <br />Seneca II-W Mine provide transmissivity values ranging from <br />0.32 to 72.0 ft2/day. In his study of the Mesaverde Group, <br />Stewart (1983) states that Wadge Overburden transmissivities <br />range from 3.1 to 43 ftz/day. Data from the nearby Energy Fuel <br />• Mines provide transmissivities of 8.3 to 43 ftz/day. <br />A pumping test of the Wadge Coal aquifer conducted by Peabody <br />personnel in 1980 at Seneca II produced a transmissivity of <br />42.6 ftz/day and a hydraulic conductivity of 4.3 ft/day. <br />Aquifer tests at Seneca II-W indicate that the Wadge Coal in <br />this area has much poorer water yielding capabilities; <br />transmissivities range from 0.03 to 0.36 ftz/day and hydrau]ic <br />conductivities range from 0.003 to 0.2 ft/day. Stewart (1983) <br />lists Wadge Coal transmissivities ranging from 0.2 to 95 <br />ft2/day, and hydraulic conductivities of 0.1 to 0.6 ft/day. <br />Based on aquifer tests conducted at the Seneca II-W Mine, the <br />Wolf Creek Coal aquifer has a transmissivity of 0.0001 to 0.20 <br />ftz/day and a hydraulic conductivity of 0.0001 to 0.01 ft/day. <br />Although no other information regarding the Wolf Creek Coal <br />aquifer could be found in the literature, Stewart (1983) gives <br />• a transmissivity of G.4 ftz/day and a hydraulic conductivity of <br />0.007 ft/day for a formation described as the 4lolf Creek Coal <br />and Underburden. <br />7-47 .Revised 04/30/90 <br />
