Converting oil shale into fuels marketable through existing channels requires large-scale mining and processing. The mining and processing operations will consume large amounts of water and will vary from plant to plant. Variations in types of resources and the products produced will lead to a variety of mining and processing schemes each with their own water use patterns. This report describes several of these schemes, as well as their water use and waste water production patterns, water treatment plant designs and costs, and opportunities for internal water reuse and recycling.
