Editor's note: This briefing covers national issues but is of particular interest to media outlets in Arizona, California, Colorado, Nevada, New Jersey, New Mexico, Utah and Wyoming.
Competition for water is becoming more intense as the nation's population continues to grow, increasing the demands for water use in agriculture and power production.
Water quality impaired by human activities constrains water use. Perhaps less understood is that water use can degrade water quality by releasing naturally occurring contaminants, like salts, uranium and radium, into streams and aquifers, thereby constraining water availability.
Rep. Grace Napolitano, Chairwoman of the House Natural Resources Subcommittee on Water and Power, the Environmental and Energy Study Institute, and the Water Environment Federation invite you to a briefing to examine the factors that limit the water available for critical uses throughout the country. The briefing is held in cooperation with the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program.
This briefing will explain and provide examples of the connections between water use and water quality and how they can ultimately affect water availability for critical uses.
