Region 10/8 AWOP Planning Meeting

The TSC optimization team, in partnership with EPA Region 10, led a program implementation meeting December 5-7, 2017, in Coeur d’Alene, ID.  Representatives from Washington, Idaho, Oregon, Utah and EPA Region 10 attended the meeting and representatives from Montana, Colorado, and EPA Region 8 participated remotely.  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 workshop on slow sand filtration optimization during which the group completed a year-long data trending project to pilot water quality optimization goals for slow sand filters with a local northern Idaho water system. Discussion covered a range of topics, including: establishing a regional comprehensive performance evaluation (CPE) team; water treatment optimization strategies for cyanobacteria; optimizing disinfectant residual in wholesale and consecutive systems; and data integrity.  (Tom Waters, US EPA/ TSC)
