Region 3 AWOP Training and Strategic Planning Meeting

The TSC Optimization Team, in partnership with US EPA Region 3 and ASDWA, conducted a meeting and technical training event on October 22 and 23, 2013 in Gettysburg, WV. Participants included state representatives from Connecticut, Maryland, Pennsylvania, Virginia and West Virginia. The technical training was focused on implementation of a backwashing procedure known as extended terminal subfluidization wash (ETSW), which is used to reduce backwash induced turbidity spikes. The ETSW demonstration was made possible with key cooperation of staff from the Gettysburg Municipal Authority’s Marsh Creek WTP. Participating state representatives described preliminary implementation strategies for application of ETSW in their respective states. (Rick Lieberman, US EPA TSC)

Distribution System Comprehensive Performance Evaluation

During the week of September 23rd members of the Optimization Team demonstrated the Distribution System Comprehensive Performance Evaluation (DS CPE) approach in Easley, SC to the Region 4 Area-Wide Optimization Program (AWOP) program participants.

This is the first of several planned training CPEs intended to transfer DS CPE skills to the State AWOP participants. The training will ultimately enable these personnel to conduct DS CPEs and provide other technical assistance to water systems challenged with meeting the Stage 2 DBPR requirements or consistently maintaining a disinfectant residual in their system.

Technical Assistance in West Virginia

From September 17 – 19, the TSC optimization team, in collaboration with the West Virginia Bureau of Public Health and a representative of the Public Service Commission of West Virginia, provided technical assistance to staff members from two WV water systems challenged by high levels of source water manganese (a secondary-standard contaminant) and other unique problems impacting water treatment plant performance. A series of special treatment studies were conducted to optimize manganese removal and demonstrate the best approach for future implementation by utility and state personnel.
