History U.S. EPA Guidelines For Water Reuse First Guidelines for Water Reuse Published in 1980 by U.S. EPA s Municipal Environmental Research Laboratory (EPA/600/8-80-036) Prepared by CDM under Contract with U.S. EPA, Office of Research and Development EPA Symposium, Protocol Development: Criteria and Standards for Potable Reuse and Feasible Alternatives Held in 1980 Survey Found 540 Projects in 24 States 2
3 History U.S. EPA Guidelines For Water Reuse Guidelines Updated in 1992 by U.S. EPA s Office of Water and Center for Environmental Research Information (EPA/625/R-92/004) A Joint Effort between U.S. EPA and U.S. Agency for International Development (U.S. AID) and Developed under Contract with CDM Focus on Non-Potable Reuse including Urban, Industrial, and Agricultural Uses Survey Found 1900 Projects in 34 States and 18 States with Regulations and 18 with Guidelines
4 History U.S. EPA Guidelines For Water Reuse Guidelines Updated in 2004 by U.S. EPA s Office of Water and National Risk Management Research Laboratory (EPA/625/R-04/108) Incorporated 3 National Academy of Sciences Studies: Issues in Potable Reuse: The Viability of Augmenting Drinking Water supplies with Reclaimed Water (1998) Use of Reclaimed Water and Sludge for Food Crop Irrigation (1996) Ground Water Recharge Using Water of Impaired Quality (1994) Case Studies Provided
2009 Executive Order: Federal Leadership in Environmental, Energy, and Economic Performance consistent with State law, identifying, promoting, and implementing water reuse strategies that reduce potable water consumption 2012 National Academy of Sciences Report Water Reuse: Potential for Expanding the Nation s Water Supply Through Reuse of Municipal Wastewater addressed: contributions to U.S. water supply; state of treatment technology; risks, costs; barriers; and research needs 5
