Region 3 AWOP Implementation Meeting 

The TSC optimization team, in partnership with the EPA Region 3 AWOP team, led a program implementation meeting on May 8-9, 2018, in Baltimore, MD. Meeting participants included state drinking water staff from Connecticut, Maryland, Michigan, New Jersey, Pennsylvania, Virginia, and West Virginia, as well as EPA staff from Region 1, Region 5 and OGWDW’s Drinking Water Protection Division. State participants reported on their recent AWOP activities, including program impacts and case studies. Meeting topics included: incorporation of data-integrity and optimization-awareness activities into their respective sanitary survey efforts; disinfection byproduct compliance challenges and strategies; approaches for calculating CT (disinfection) at water plants; state approaches to addressing harmful algal blooms, and strategies to characterize and optimize corrosion control treatment at water systems. After the meeting, several participants also attended the Legionella 2018 Conference, also held in Baltimore that week. (Alison Dugan, Matthew Alexander; US EPA/ TSC)

Region 10/8 AWOP Planning Meeting and Workshop

The Optimization Team, in collaboration with EPA Region 10, led a technical workshop and strategic planning meeting during May 15 – 17, 2018, in Spokane, WA.  Representatives from Idaho, Oregon, Utah and Washington attended the meeting and workshop.  Remote participants included representatives from Colorado, Montana and EPA Region 8. The states provided updates on their optimization efforts and impacts of their programs on public health protection.  The technical workshop, hosted by the Vera Water & Power utility located in Spokane Valley, WA focused on tools to evaluate distribution system data integrity. The workshop demonstrated that the approach is directly applicable to a ground water system utilizing multiple wells as the water source.  Representatives of two Tribal utilities and the Indian Health Service also participated in the workshop.  (Richard Lieberman,  Tom Waters,  Alison Dugan  and Matthew Alexander; US EPA/ TSC).

Optimization Program – Region 5 PWSS Directors Meeting

On April 24, 2018, the TSC Optimization team delivered a presentation and participated remotely in a discussion with the EPA Region 5 and their state PWSS Directors about the implementation of the Area-Wide Optimization Program (AWOP). Amy Klei and Eric Oswald, representing the Ohio EPA and the Michigan DEQ, respectively, also shared recent experiences with optimization projects and AWOP. Ohio EPA emphasized the positive response from water system staff and how much state staff members were energized through involvement in the project to apply treatment optimization tools to HAB issues. The Michigan DEQ considers the current investment in staff time to be worth the expected long-term benefits from AWOP participation. The state directors were provided with this information to assist as they consider future participation in AWOP.  (Richard Lieberman, Alison Dugan and Matthew Alexander; US EPA Tecnical Support Center)
