Western oil-shale development: a technology assessment. Volume 6: oil-shale development in the Piceance Creek Basin and potential water-quality changes
This report brackets the stream quality changes due to pre-mining pumping activites required to prepare oil shale lease Tracts C-a and C-b for modified in situ retorting. The fluxes in groundwater discharged to the surface were identified for Tract C-b in a modeling effort by another laboratory. Assumed fluxes were used for Tract C-a. The quality of the groundwater aquifers of the Piceance Basin is assumed to be that reported in the literature. The changes are bracketed in this study by assuming all premining pumping is discharged to the surface stream. In one case, the pumped water is assumed to be of a quality like that of the upper aquifer with a relatively high quality. In the second case, the pumped water is assumed to come from the lower aquifer. Complete mixing and conservation of pollutants was assumed at sample points at the White River and at Lees Ferry of the Colorado River. A discussion of possible secondary effects of oil shale and coal mining is presented. In addition, a discussion of the uncertainties associated with the assumptions used in this study and alternative uses for the water to prevent stream contamination by oil shale development is provided.
