A plan for hydrologic investigations of in situ, oil-shale retorting near Rock Springs, Wyoming
Kent C. Glover, E. A. Zimmerman, L. R. Larson, J.C. Wallace
1982, Open-File Report 82-758
The recovery of shale oil by the in-situ retort process may cause hydrologic impacts, the most significant being ground-water contamination and possible transport of contaminants into surrounding areas. Although these impacts are site-specific, many of the techniques used to investigate each retort operation commonly will be the same. The U.S....
