<br /> <br />W <br />Iol:lo <br />/-4 <br />o <br /> <br />ABSTRACT <br /> <br />Maps were made of the Upper Colorado River Basin showing loca- <br />tions of coal deposits, oil and gas, oil shale, uranium, and tar" sand, <br />in relationship to cities and towns in the area. Superimposed on <br />these are locations of wells showing four ranges of water quality; <br />1,000-3,000 mg/l, 3,000-10,000 mg/1, 10,000-35,000 mg/1, and over <br />35,000 mg/I. Information was assembled relative to future energy- <br />related projects in the upper basin, and estimates were made of their <br />anticipated water needs. <br /> <br />Using computer models, various options were tested for using <br />saline water for coal-fired power plant cooling. Both cooling towers <br />and brine evaporation ponds were included. Information is presented <br />of several proven water treatment technologies, and comparisons are <br />made of their cost effectiveness when placed in various combinations <br />in the power plant makeup and blowdown water systems. A relative <br />value scale was developed which compares graphically the relative <br />values of waters of different salinities based on three different <br />water treatment options and predetermined upper limits of cooling <br />tower circulating salinities. <br /> <br />Coal from several different mines was slurried in waters of dif- <br />ferent salinities. Samples were analyzed in the laboratory to determine <br />which constituents had been leached from or absorbed by the coal, and <br />what possible deleterious effects this might have on the burning proper- <br />ties of the coal, or on the water for culinary use or irrigation. <br /> <br />iii <br /> <br />
