<br />n r. ".. "'... " <br />uU~~.~~: <br /> <br />. <br /> <br />. <br /> <br />-4- <br /> <br />In addition to the foregoing, I would like to introduce, for <br /> <br />consideration by the Subcommittee, a proposed action program lead- <br /> <br />ing to eventual control and m~nagement of the increasing salinity <br /> <br />levels in the Colorado River; one of the more pressing problems <br /> <br />in that great river basin. Salinity concentrations increase as <br /> <br />the result of depletions of water throughout the system and addi- <br /> <br />tions of dissolved materials resulting from irrigation and industry. <br /> <br />This problem has been given close attention by individuals, states, <br /> <br />federal, and international agencies, partially as the direct result <br /> <br />of the Water Quality Act of 1965 and partially due to their own <br /> <br />interest in the control, conservation, and utilization of waters <br /> <br />of the river system. The Bureau of Reclamation has proposed a <br /> <br />number of "point source" studies to test some of the proposed control <br /> <br />methods. These studies would be conducted in both the Upper and <br /> <br />Lower Basins. The studies should begin in fiscal year 1972. <br /> <br />Necessary funding should be provided. It is hoped that the studies <br /> <br />would later combine into a basin-wide proposal that would lead to <br /> <br />alleviation of the salinity problem under a federal program. It is <br /> <br />imperative that these feasibility studies be initiated at once in <br /> <br />order to determine the magnitude and the best methods of alleviating <br /> <br />
