Abstract |
Potential ground water problems associated with Modified In Situ (MIS) oil shale retorting need to be examined in order to minimize or mitigate possible invasion of spent shale leachates into ground water systems in actively mined or mined and abandoned sites. This background report on the hydrology, mineralogy, and ground water chemistry of the Green River Formation of the Piceance Basin has been compiled in order to provide a comprehensive document on what is known about the three physico-chemical systems which will interact to produce ground-water quality variations at an uncontrolled mine site in the Piceance Basin and more specifically, at either of two federal lease tracts, Ca and Cb, situated therein. |
