Water 2025's <br />goal is to significantly aid <br />technological advances and identify <br />new supplies. Interior can facilitate <br />research to reduce the high costs that <br />slow adoption of new water <br />purification technologies. <br />✓A part of the effort to identify new <br />potential sources of water would be to <br />task the U.S. Geological Survey <br />(USGS) with the comprehensive <br />study of untapped but impaired <br />supplies, with a focus on those places <br />with a high probability of water <br />demands exceeding supplies by <br />2025. <br />Various private entities, academic <br />institutions, and state and federal <br />agencies are engaged in research <br />that could be better coordinated and <br />focused. Recent reports to Congress <br />on potential projects, along with a <br />water desalination research roadmap <br />now under review by the National <br />Research Council, should guide <br />research. <br />it :a <br />v .Q <br />Reducing desalination costs, for <br />instance, could enable the cost - effective <br />treatment of brackish groundwater in <br />traditionally water -short areas. In some <br />rural communities and Indian <br />reservations, this salty groundwater is <br />unusable for human consumption, <br />limiting growth and prosperity. Although <br />one alternative is to pipe fresh water <br />from rivers and reservoirs miles away to <br />these water short areas, desalination <br />could offer less expensive and drought - <br />proof alternative while providing reliable <br />and high quality water supplies to these <br />communities. <br />Remote water data collection <br />technology <br />V <br />
