Region 6/7 Area-Wide Optimization Program.

The TSC optimization team, in partnership with EPA Regions 6 and 7, led a program implementation meeting October 24-26, 2017, in New Orleans, LA.  Representatives from Arkansas, Iowa, Kansas, Louisiana, Missouri, New Mexico, and Oklahoma attended.  The states provided updates on their optimization efforts and highlighted performance data and impacts of their programs on public health protection. The event included a technical training workshop about a disinfectant byproduct (DBP) surrogate method that may be useful as a process monitoring tool at water systems challenged by DBP formation. Discussion covered a range of topics, including: approaches to integrate data integrity review into sanitary surveys; optimizing chlorine residual in distribution systems; implementing an AWOP awards program; and integrating optimization concepts into operator certification.  (Matthew Alexander, U.S. EPA Technical Support Center).
