Algal Toxin Workshop

Algal toxins that break through water treatment can significantly disrupt the delivery of drinking water, as  Salem, Oregon and Toledo, Ohio have experienced in recent years.  Although monitoring for algal toxins is not currently required by the Safe Drinking Water Act, as part of UCMR4 many utilties will be required to sample their finished water for multiple algal toxins.  Many water systems in Oregon that serve surface water are also required by a recent Oregon rule to monitor for algal toxins.

This workshop organized by PNWS-AWWA's Research and Water Treatment Committees provides a comprehensive overview of algal toxin management, including source water management and monitoring, methods of analysis, and treatment options. Real-world experiences from managing the algal toxin events in both Salem, Oregon and Toledo, Ohio will be presented.  Guidance on public communication of algal toxin health risks will also be presented.

0.6 CEUs are approved for both OR and WA.

Early Bird registration fee is $75 for members and $100 for non-members.  This discounted cost is available through February 28 and will increase by $25 beginning March 1.  Workshop cost includes snacks, beverages, and lunch.
