Preliminary Geologic and Hydrologic Studies of Selected Areas in Culberson and Hudpseth Counties, Texas

In June 1986, the Bureau of Economic Geology (BEG) was asked by the Texas Low-level Radioactive Waste Disposal Authority to conduct a preliminary study of the geology and hydrology of two sites being considered for construction of a low-level radioactive waste repository. Both sites are located in northern Hudspeth County, Texas.

The rocks below potential sites are Precambrian rhyolite porphyry and Cretaceous limestone interbedded with some sandstone and mudstone. The geologic investigations provide data for evaluation of the general geologic framework of the proposed sites and provide site-specific data for evaluation of the physical and structural character of the rock units.
