Participants included representatives of drinking water programs from Alaska, Oregon, Utah and Washington. The EPA Region 10 office hosted the meeting in Seattle, where the participants reported on individual state AWOP implementation efforts. This was followed by a discussion of technical and implementation topics which resulted in action items to move the program forward. The workshop was conducted at the Deer Creek water treatment plant in cooperation with the Olympic View (WA) Water & Sewer District. The workshop objectives included identification and development of optimization strategies for contact adsorption clarifiers using buoyant media.

During the strategic implementation portion of the meeting, Bill Mundy (Regional Municipality of Halton, Ontario Canada) provided a presentation through Adobe Connect on the effective use of particle counters for indirect integrity monitoring of a membrane filtration plant. This information is directly applicable to the development of membrane optimization procedures by the Region 10 AWOP participants. (Rick Lieberman, US EPA, TSC).

Region 6 AWOP Strategic Planning Meeting

The TSC optimization team, in partnership with EPA Region 6 and ASDWA, led a strategic planning meeting and technical training event from May 6-8, 2014 in Texarkana, AR. Participants included state drinking water program representatives from Arkansas, Iowa, Louisiana, Missouri, New Mexico, Oklahoma, Texas, and US EPA Region 7. The technical training workshop, held at a nearby water system, provided participants an approach to assess disinfection and nitrification in a chloraminated distribution system. During the planning meeting, states discussed a variety of topics, including feedback on the proposed goals for chloraminated water systems, suggested “next steps” for Missouri’s recently established optimization program, and how to integrate CPE training into capacity development. This was the first AWOP training and planning meeting where a representative from US EPA Region 7 was able to attend. With the recent addition of Missouri, two of the four Region 7 states now participate in AWOP. US EPA Region 7 plans to send a representative to future Region 6 AWOP meetings to support their states’ participation in AWOP. (Matthew Alexander US EPA, TSC)
