Region 4 AWOP Strategic Planning Meeting and Workshop

The TSC optimization team, in partnership with Region 4 and ASDWA, led a training exercise and strategic planning meeting September 29-30, 2015 in Atlanta, GA. Participants included state drinking water program representatives from Alabama, Florida, Kentucky, North Carolina, and South Carolina. Efforts focused on identifying potential roles for third party technical assistance (TA) providers to support AWOP goals and objectives. Investigative distribution system sampling, a fundamental optimization activity, was identified as a priority for TA provider support. Each state developed an approach, with associated action items, to engage the TA provider organizations in an optimization training program for water system staff. A training module demonstration for TA providers is being developed and follow up on each state’s action items will occur at the next R4 AWOP meeting. (Richard Lieberman, US EPA, TSC)

Chloraminated Distribution System Optimization Development

During the summer of 2015, members of the Optimization Team piloted two distribution system comprehensive performance evaluations (DS CPE) at chloraminated water systems. The first was conducted in Archdale, NC, in partnership with the North Carolina Department of Environment and Natural Resources. The second was in Greenville, PA, in partnership with the Pennsylvania Department of Environmental Protection. One system had very stable influent water quality that they were able to maintain throughout their system, while the other system was challenged with very unstable influent water quality. Piloting the approach at two very different systems validated that the tool could be successfully applied to a variety of system, ranging from those nearly optimized to those nearly out of compliance. The team will next be developing approaches to address water quality concerns through a technical-assistance or operator training project. (Matthew Alexander, & Alison Dugan, US EPA, TSC)
