ASDWA PFAS – Source Water Protection Guide and Toolkit

ASDWA developed this guide and toolkit with support from a Project Advisory Council (PAC) with representatives from nine states (Colorado, Kansas, Minnesota, New Hampshire, North Carolina, Pennsylvania, Vermont, Virginia, and Wisconsin), and the Cadmus Group. The purpose of the guide is to demonstrate and share effective strategies for addressing PFAS contamination risk in source waters that will help inform policy decisions, assist state drinking water programs in protecting public health, and encourage collaboration and communication among states and water utilities.

The Association of State Drinking Water Administrators (ASDWA) is the professional Association serving state drinking water programs. Formed in 1984 to address a growing need for state administrators to have national representation, ASDWA has become a respected voice for state primacy agents with Congress, the United States Environmental Protection Agency (EPA), and other professional organizations.

Elevating Drinking Water as a National Priority

One of the most important roles ASDWA has is to make sure no one stops thinking about water. Whether that means spending time on the Hill to speak with Congressional staff about drinking water issues, or expanding the reach of our communications to the public by way of social media, ASDWA is constantly working to advance our message of public health protection on behalf of our members. Having safe drinking water is taken for granted by many, so ASDWA continually emphasizes drinking water’s importance for public health and for the economy.

Cyanotoxin Treatment Options, Optimization, and Barriers

Original Broadcast: December 3, 2018

Slide Decks:

This webinar will provide state drinking water programs with a better understanding of analytical methods that are available for algal toxins and recommendations for water utilities on how they should interpret the 10-day health advisory. Presenters will provide an overview of cyanotoxin analysis methods, cover the benefits and limitations of methods, and cyanotoxin issues in Salem, OR.

Webinar Agenda:

Drinking Water Treatment Options for Cyanotoxins: Tom Waters Environmental Engineer with U.S. EPA’s OGWDW in Cincinnati, Ohio will provide an overview of drinking water treatment options for surface water systems impacted by harmful algal blooms (HABs). Topics will include cyanobacterial cell and cyanotoxin removal through coagulation, sedimentation and filtration; removal of cyanotoxins by adsorption; cyanotoxin degradation by oxidation; and associated water treatment plant operational considerations.

“Real World” Cyanotoxin Treatment Optimization: Heather Raymond Public Water System HAB Coordinator with Ohio EPA’s Division of Drinking and Ground Waters, There are a variety of treatment processes that can be optimized for cyanotoxin removal and calculators are available to estimate treatment efficiency. This webinar will provide insights on cyanotoxin adsorption capacity and microcystins oxidation that Ohio EPA has gained through real world examples and jar testing and hold time studies conducted using cyanotoxins derived from public water system source waters. Ohio EPA’s treatment technique rules and cyanotoxin treatment guidance will also be discussed.

Monitoring Algal Toxin Treatment Barriers Using Decision Support Software: Dr. Christopher Miller is the founder of Fontus Blue, Inc will cover A case study involving a surface water plant in Ohio with persistent microcystin concentrations in their source water will be discussed, as well as their unique approach using decision support software to monitor and manage their algal toxin treatment barriers during HAB events. The approach has resulted in enhanced operational awareness, efficiency, and successful treatment of microcystin to acceptable levels. Simultaneous compliance challenges associated with other water quality measures (e.g. disinfection byproducts) will also be discussed.
