They are also further studying <br />possible locations for the pipeline from Ruedi Reservoir <br />along the Fryingpan River. The goal is to establish the <br />most economical location that will not unduly interfere <br />with aesthetics and the environment. <br /> <br />Salinity Studies <br /> <br />FWQA funded a demonstration grant study near <br />Grand Junction, Colorado, to determine the effectiveness <br />of canal and lateral lining in reducing saline outflow to <br />the Colorado River. Results of this study should be avail- <br />able early in 1972. <br /> <br />The Bureau of Reclamation now proposes to launch <br />feasibility studies to determine the best method of control- <br />ling salinity in the Colorado River Basin under authority <br />of the various public laws related to quality of water. <br />Initial efforts would be made in FY 1971 and FY 1972 with <br />limited funds available in the Bureau's program. An ex- <br />panded program would be launched in FY 1973. Studies will <br />be handled by both Region 3 and Region 4 and begin with <br />the Laverkin Springs on the Virgin River, Paradox Valley in <br />western Colorado, and Crystal Geyser in eastern Utah. <br /> <br />The Colorado Water Conservation Board has just <br />received a final report prepared by the Ken R. White Company <br />of Denver, Colorado and the URS Research Company of San Mateo, <br />California , on Improving Municipal Water Supplies by De- <br />salting. This report which was made for the Water Board and <br />the Office of Saline Water, considered the feasibility of <br />desalting in six selected communities in Colorado, with <br />water having total dissolved solids ranging from 565 to 3075 <br />milligrams per liter. The populations of these communities <br />varied from 2,600 to 9,000 people. The estimated costs for <br />desalting with reverse osmosis ranged from $0.76 to $1.22 <br />per 1000 gallons. <br /> <br />CWCB/LDM/mm - 5/26/71 -3- <br />
