Haught*, R C. AND J Hall. EVALUATION OF SENSOR AND MONITORS TO DETECT CHANGES IN WATER QUALITY. Presented at WSWRD Peer Review, Cincinnati, OH, September 27 - 29, 2004.
Impact/Purpose:
To inform the public.
Description:
The safety and security of distribution systems has come under reassessment in the past year. Several chemical and biological agents have been identified that might constitute a credible threat against water supply systems. There have also been a few reported threats against water systems. Any attempt could cause a significant impact on the confidence in the infrastructure distribution systems. Issues ranging from public safety and health, ecological, and national security are under consideration. The U.S. Environmental Protection Agency (EPA) has been working to be proactive in the anticipation, detection, and identification of the threat of deliberate or accidental contamination of water distribution systems and supplies. Real-time monitoring of water quality is essential to effectively respond to deliberate, natural, and/or accidental human-caused conditions that may threaten the safety and health of US citizens. EPA is evaluating the value of various instruments and developing performance criteria for remote on-line real-time monitors to support the security of distribution systems from accidental or deliberate injection of contaminants into a distribution system. This work is being conducted at EPA's Test and Evaluation (T&E) Facility in Cincinnati, Ohio.
