Wells GB-2, GBB-2, GC-2 and GP-9 have somewhat similar ranges of <br />transmissivity and permeability with average values being 19 gal/day/ft and 0.14 <br />ft/day, respectively. The Third White Sandstone is much more permeable near well <br />P-8. <br />Second White Sandstone <br />The Second White Sandstone lies stratigraphically above the G coal seam. <br />Aquifer tests have been done on four wells in the Second White Sandstone, wells <br />GE-3, P-4, P-5 and P-6. <br />Transmissivities for these wells have a wide range. Wells P-4, P-5 and P-6 <br />are much more shallow completions than well GE-3 and transmissivities for wells P-5 <br />and P-6 are much higher than wells GE-3 and P-4. The Second White Sandstone near <br />wells P-4 and CE-3 may be much less transmissive due to problems in the completion <br />of the well. The transmitting ability of the Second White Sandstone near wells P-5 <br />and P-6 was measured at 780 and 1500 gpd/ft while permeabili[ies of this aquifer in <br />these areas varied from 4.5 to 12 ft/day. These aquifer properties are thought to <br />be indicative of the Second White Sandstone aquifer near its outcrop. <br />Lewis Shale <br />The Lewis Shale is composed of uniform dark gray to tan shale with minor <br />occurrences of thin sandstone strata. The shale has a low permeability, and it acts <br />more as an aquiclude (confining bed) than as an aquifer or aquitard.
