• this area to be retarded as a potential aquifer. <br />2. Ground 1!,:r~r <br />The occurrence of ground water in the subject tracts is <br />controlled largely by tl~e topograpf~y, geologic stru~- <br />tune, and permeability of rocks immediately underlying <br />the surface through which recharge must occur, all <br />three tracts lie on moderate to steeply sloping dip- <br />slopes a'_ong the backslope of which beds overlying the <br />Wedge coal are truncated by erosion. Also, these beds <br />often are excosed in the sides of stream valleys ou: <br />into the dipslope surface. Ground-water recharge, <br />therefore, is li~ited to the narrow band c+here beds <br />• crop out along the steep backslope of the structure and <br />to downward perco'_atior. on the di slope surface itself. <br />Partly because of low permeability of beds ir..aediately <br />underlying the surface and party because of the <br />opportunity for drainage of these beds afforded by <br />valleys incised into the dipslope surface, very little <br />ground-water recharge to depth is occurring Ln these <br />areas. Moreover, normal faulting transverse to the <br />direction of strike and inferred directional pera;ea- <br />bility paral'_eling the direction of stri're apparently <br />greatly retard the movement of ground water down dip. <br />Quantitative ground-eater studies undertaken by Energy <br />J <br />J9 <br /> <br />
