Stage 2 DBPR: Understanding, Managing THM Formation Is Key for Compliance in Consecutive Systems

摘要

The buying and selling of treated water is common practice in the United States. Consecutive systems (CS) - public water systems that buy or receive some or all of their finished water from one or more wholesale systems (WS) - are responsible for serving nearly one-third of the water customers in the U.S.1 Prior to the promulgation of the Stage 2 Disinfectants and Disinfection Byproducts Rule (DBPR), most Safe Drinking Water Act (SDWA) regulations, including Stage 1 DBPR, did not specifically address consecutive systems. However, the newly-implemented Stage 2 DBPR includes monitoring and compliance requirements for consecutive systems with respect to disinfection byproducts (DBPs).
