Region 10/8 Area-Wide Optimization Program  

The TSC optimization team, in partnership with EPA Region 10, led a program implementation meeting October 23-25, in Portland, OR.  Representatives from Washington, Oregon, Utah and EPA Region 10 attended the meeting and representatives from Montana, Colorado, Idaho and EPA Region 8 participated remotely.  The states provided updates on their optimization efforts and highlighted performance data and impacts of their programs toward enhancing public health protection. The event included a workshop on a modified filter backwash technique called extended terminal subfluidization wash (ETSW) at the Lake Oswego-Tigard water treatment plant. Discussion covered a range of topics, including: slow sand filtration optimization; training for small systems on reducing health-based violations (in support of the EPA initiative); and using water treatment plant alarms to support optimization.

Oregon HABs Workshop

On August 23rd, TSC participated in the Oregon Health Authority Permanent Cyanotoxin Regulation Workshop/Webinar. TSC presented information on the EPA drinking water method development process, technical details and overviews of EPA drinking water cyanotoxin methods, and explanations of the results of the discussed methods. Discussions also included how the EPA drinking water cyanotoxin methods were being applied to the UCMR 4 Program. The workshop was primarily attended by Oregon drinking water laboratories and public utilities in preparation for State regulatory decisions being made on cyanotoxins and HABs.

Region 4 AWOP Planning Meeting and Corrosion Control Workshop

The TSC optimization team, in cooperation with EPA Region 4 and ASDWA, hosted a technical workshop and strategic planning meeting on July 17 & 18, 2018 in Cincinnati, OH. Participants included state drinking water program representatives from Alabama, Florida, Kentucky, North Carolina, South Carolina and Ohio. States presented their AWOP implementation reports, including a description of activities over the past quarter and resulting water quality impacts. The technical workshop, led by TSC and ORD staff, focused on corrosion control and how it might be incorporated into AWOP activities. EPA Region 5 and Ohio EPA participated in this meeting as guests/observers to assess future participation in the program. (Richard Lieberman, US EPA/ TSC).

Region 6/7 AWOP Planning Meeting and Workshop 

 TSC’s Optimization Team, in collaboration with EPA Regions 6 and 7, led a technical workshop and strategic planning meeting from May 22-24, 2018, in Lawrence, KS.  Representatives from Arkansas, Iowa, Kansas, Louisiana, Missouri, New Mexico, and Oklahoma attended the meeting and workshop.  States provided updates on their drinking water optimization programs, including program impacts and case studies.  The technical workshop, hosted by the City of Lawrence Clinton Reservoir Water Treatment Plant, introduced the states to a jar test procedure that may be used to evaluate disinfectant byproduct (DBP) precursor removal.  States may use this procedure to assist drinking water systems that are challenged with DBP compliance issues.  (Matthew Alexander, US EPA/ Technical Support Center).

Region 4 AWOP Strategic Planning Meeting and Workshop: 

The TSC optimization team, in cooperation with EPA Region 4 and ASDWA, led a technical workshop and strategic planning meeting from April 9-12, 2018 in Albertville, AL. Participants included state drinking water program representatives from Alabama, Florida, Kentucky, North Carolina, South Carolina and Tennessee. State representatives presented their AWOP annual implementation reports, including AWOP activities and resulting water quality impacts. Improvements in small system performance were evident in the annual reports.  The technical workshop, hosted by Albertville, AL water system staff, focused on tools to evaluate distribution system data integrity.
