The EPA Water Security Division has developed a program that provides information, case studies and a framework utilities can use to develop a Water Quality Surveillance and Response System (SRS). An SRS can help improve a utility's ability to monitor source water and distribution system water quality and to quickly detect and respond to any issues that arise. The resources are now available online, including a comprehensive list of products and programs the agency has developed to help utilities understand and design SRS. The document covers tools and guidance that are already available as well as ones upcoming with expected release dates.
