Optimization Program ­­– EPA Small Systems Webinar

On June 5th, Tom Waters (of TSC’s Optimization Team), co-presented with Nick Dugan (of ORD/NRMRL) in the ORD/OW Small Systems Webinar Series. Their presentation, entitled Conventional Treatment Options for Harmful Algal Blooms, focused on surface waters impacted by harmful algal blooms (HABs). Topics included cyanobacterial cell and cyanotoxin removals through coagulation, sedimentation and filtration; propagation of cyanotoxins and indicator parameters of cyanobacterial biomass through a surface water treatment facility; removal of cyanobacterial toxins by powdered activated carbon (PAC); the impact of permanganate oxidation on cyanobacterial cell integrity, toxin release, and toxin degradation; and toxin degradation by free chlorine. A considerable amount of information shared during this presentation was attained through the Optimization Team’s pilot project with Ohio EPA to develop a HAB-focused water treatment plant “comprehensive performance evaluation” (CPE) tool.  Almost 1,400 attendees participated, representing all 50 states, 10 EPA Regions, 10 Tribal Nations, 1 territory, and 14 countries (Tom Waters, 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).
