<br /> <br />C) <br />..-:;J <br />f..... <br />(D <br />en <br />..;;:.. <br /> <br />In a cooperative effort with the Office of Saline Water, a preliminary <br />study of the feasibility of applying ion exchange technology was <br />completed in 1972. This report indicated that with the development <br />of the technology it mighc be possible to achieve very large scale <br />river quality control at the 500-mg/l level. Product water recovery <br />will be expected to vary between 89 and 95 percent. However, con- <br />siderable problems are foreseen in applying ion exchange processes <br />on a large scale. Therefore, under the Salinity Control Act, attention <br />will be directed toward developing conceptual designs for handling <br />water volumes more closely alined with the major diversions anticipated <br />in future years. <br /> <br />Another study is the Lake Powell Research Project (LPRP), officially <br />entitled "Collaborative Research on Assessment of Man's Activities <br />in the Lake Powell Region." This study is being conducted by a <br />consortium of academic institutions under the sponsorship of the <br />Research applied to National Needs (RANN) program of the National <br />Science Foundation. The Project formally came into existence in <br />1971. The Bureau of Reclamation has cooperated with the Project by <br />a complete interchange of data, assistance in fieldwork, and limited <br />financial support for those subprojects that have direct application <br />to operational programs of the reservoir. The LPRP consists of 16 <br />subprojects, covering a wide range of disciplines. Four of the sub- <br />projects deal with some aspect of the water quality of Lake Powell. <br />These are (1) Cultural Eutrophication, (2) Heavy Metals, (3) Geo- <br />chemistry, and (4) Physical Limnology. <br /> <br />Yet another study is directed at return flow utilization. The <br />energy crisis has focused new attention on western water supplies <br />to meet projected cooling water requirements for energy conversion <br />and power production. Projected water consumption for power <br />generation, coal conversion and oil shale development could remove <br />as much as 870,000 acre-feet of fresh water from the Colorado River <br />Basin by 2000. Water of high quality will not be available in suf- <br />ficient quantity to supply all needs as envisioned. However, most <br />energy uses of water for cooling and production processes will not <br />require water of high quality and indeed may use flows that have a <br />high mineral content without significant detrimental results. <br />Investigations are to commence in FY 1976 to evaluate systems for <br />collecting the highly saline flows from irrigation return water prior <br />to their entry into the Colorado River and to utilize the water for <br />some beneficial purpose. <br /> <br />Subjects for these investigations include the Grand Valley Collector <br />System in Colorado, where water supplies for oil shale will be <br /> <br />8 <br /> <br />. <br /> <br />
