Distribution System Optimization Pilot Training in Pennsylvania: 

On October 24th, the Optimization Team partnered with the Pennsylvania Department of Environmental Protection to pilot a workshop on Distribution System Optimization (DSO) for parent and consecutive water systems that use chloramine disinfection.  The workshop topics included an overview on DSO, discussion among the seven participating systems about their current monitoring activities and objectives, a review of sampling and analysis procedures, and discussion of potential (enhanced) distribution system monitoring. Candidate future topics were also discussed, including fundamentals of chloramines, strategies to effectively manage a system during a chlorine conversion (burn), and approaches for improving water quality and addressing nitrification. The next workshop is tentatively planned for Spring 2018.  (Alison Dugan and Matthew Alexander, US EPA TSC)
