DENVER — The American Water Works Association (AWWA)’s new Cyanotoxins Resource Community can help utilities develop treatment responses to cyanotoxins, according to a press release.

The free tools are offered in partnership with Hazen and Sawyer and Utah State University, noted the release.

“The new Web page includes a spreadsheet tool to assess removal of extracellular cyanotoxins by chlorine, ozone, chlorine dioxide and potassium permanganate,” stated the release. The calculator is based on peer-reviewed literature to provide the best available cyanotoxin oxidation material.

Utilities can use the spreadsheet to assess existing treatment processes and to consider treatment alternatives, reported the release.

Other resources include benchtop test protocols to help utilities remove cyanotoxins use their own water, shared the release. Oxidation process testing and “jar testing to assess removal by powered activated carbon addition” have their own protocols.
