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 3 AWOP Planning Meeting and Workshop

The TSC optimization team, in partnership with the Region 3 AWOP team, led a program implementation meeting on December 12-14, 2017 in Philadelphia, PA.  Meeting participants included a mix of those regularly involved (i.e., Maryland, Pennsylvania, Virginia, West Virginia, EPA’s Drinking Water Protection Branch and ASDWA), as well as those interested in learning more about the program (i.e., personnel from New Jersey and EPA Regions 1 and 5). Michigan, which recently announced their intent to join AWOP, attended this as their first multi-state AWOP meeting.

All participants provided reports on their recent AWOP activities and/or their interest in the program.  The technical topic, distribution system data integrity, was embraced by participants as a potential activity for smaller systems. Topic discussed during the strategic planning meeting included Legionella (i.e., understanding treatment options, approaches for consecutive systems); next steps for new/interested AWOP states; flushing approaches to enhance water quality; drinking water program metrics; and simultaneous compliance challenges.

Region 4 AWOP Strategic Planning Meeting and Workshop

The TSC optimization team, in partnership with EPA Region 4 and ASDWA, led a November 7-9 technical training workshop and strategic planning meeting in Frankfort, KY.  Participants included state drinking water program representatives from Alabama, Florida, Kentucky, North Carolina, South Carolina and Tennessee. States presented updates on their AWOP activities and resulting water quality impacts. The technical workshop, at the Nicholasville, KY water treatment plant, focused on evaluating corrosion control treatment. Discussion topics included a variety of PWSS and AWOP implementation issues.

Region 10/8 AWOP Planning Meeting

The TSC optimization team, in partnership with EPA Region 10, led a program implementation meeting December 5-7, 2017, in Coeur d’Alene, ID.  Representatives from Washington, Idaho, Oregon, Utah and EPA Region 10 attended the meeting and representatives from Montana, Colorado, and EPA Region 8 participated remotely.  The states provided updates on their optimization efforts and highlighted performance data and impacts of their programs on public health protection. The event included a workshop on slow sand filtration optimization during which the group completed a year-long data trending project to pilot water quality optimization goals for slow sand filters with a local northern Idaho water system. Discussion covered a range of topics, including: establishing a regional comprehensive performance evaluation (CPE) team; water treatment optimization strategies for cyanobacteria; optimizing disinfectant residual in wholesale and consecutive systems; and data integrity.  (Tom Waters, US EPA/ TSC)

Region 3 Area-Wide Optimization Program

The TSC optimization team, in partnership with EPA Region 3 and ASDWA, held a one-day planning meeting on October 27, 2015, in Harrisburg, PA.  State drinking water program representatives from Connecticut, Maryland, Pennsylvania, Virginia, and West Virginia reported on their respective AWOP implementation efforts, including technical assistance efforts to control disinfection byproducts, maintain disinfectant residual, and investigate turbidity data integrity issues within their water systems. Meeting discussion topics included next steps related to data integrity (evaluations and follow-up), application of AWOP to address harmful algal blooms, and disinfection data integrity training (planned for the next Region 3 AWOP meeting in the spring of 2016).

Region 6 & 7 AWOP Strategic Planning Meeting

The TSC optimization team, in partnership with Region 6, Region 7, and ASDWA, led a strategic planning meeting and technical workshop on May 5th – 7th in Dallas, TX.   Representatives of drinking water programs from Arkansas, Iowa, Louisiana, Missouri, New Mexico, Oklahoma, and Texas reported on ongoing AWOP implementation efforts and reported on water quality improvements in their state.  Kansas drinking water program staff members also participated in the meeting to learn more about the AWOP.  Due to increased participation from Region 6 and 7 states, two simultaneous workshops were conducted to accommodate the size of the group.  A disinfection data integrity workshop was conducted at Park Cities MUD water treatment plant and a turbidity data integrity workshop was conducted at the City of Midlothian water treatment plant.  Significant topics during the meeting included prioritization of system performance, DBP optimization, and the difference between detectable and measurable chlorine residual.  Meeting participants plan to incorporate the workshop concepts and information from group discussions into their respective state’s PWSS program activities.  (Matthew Alexander, US EPA, TSC)

Region 10 AWOP Strategic Planning Meeting

The TSC optimization team, in partnership with ASDWA, led a remote strategic planning meeting from May 19 to 21, 2015 in Spokane and Kennewick, WA.   Representatives of drinking water programs from Oregon, Washington, and Utah reported on ongoing AWOP implementation efforts.  US EPA Region 8, Colorado, Idaho and Montana drinking water program staff members also participated in the meeting, both in person and remotely, to learn more about the program.  A membrane workshop focused on data integrity and log removal value verification at the City of Kennewick, WA water treatment plant.  Representatives of EPA R8, CO, ID and MT were very positive about the value of AWOP and will continue discussion and garnering interest in their home offices for future participation.  (Tom Waters & Rick Lieberman US EPA, TSC)

Region 3 AWOP Strategic Planning Meeting

The US EPA, TSC optimization team, in partnership with Region 3 and ASDWA, held a strategic planning meeting and technical workshop on April 7-9, 2015 in Maryland. State drinking water program representatives from Maryland, Pennsylvania, Virginia, and West Virginia reported on their respective AWOP implementation efforts and presented positive water quality impacts. Four DWPD staff members also joined the AWOP participants in a distribution system optimization workshop conducted at the Bowie, MD water system. The title of the workshop was “Assessing Distribution System Water Quality and Potential Follow-Up Studies and Control Strategies.” State participants provided positive feedback on the outlined approach and especially on the use of free chlorine residual as a key indicator of water quality.

Region 4 AWOP Strategic Planning Meeting

The TSC optimization team, in partnership with EPA Region 4, led a training exercise and strategic planning meeting from March 10-12, 2014 in Cullman, AL. Participants included state drinking water program representatives from Alabama, Florida, Kentucky, North Carolina, and South Carolina. The training focused on optimization approaches/tools for Stage 2 DBP Rule compliance assistance. It was supported by the Alabama AWOP team, who shared techniques for enhancing communication between parent and consecutive systems and encouraging combined responsibility for water quality. The training also featured a panel of operators from the Cullman water treatment plant and their consecutive systems, who discussed their perspectives about maintaining water quality in their systems. Meeting topics included: promoting the “combined distribution system” concept; tracking/prioritizing systems for DBP performance; expanding technical assistance provider resources; using optimization tools to support RTCR implementation; and marketing AWOP.  (Alison Dugan & Richard Lieberman US EPA, TSC)
