Cyanobacteria/Cyanotoxins

AWWA Resources on Cyanobacteria/Cyanotoxins

cyanotoxins

Cyanobacteria, also known as blue-green algae, are photosynthetic bacteria that can live in many types of water. 

They are important primary producers (organisms that make energy directly from the sun) in aquatic ecosystems. While critical to water and soil resources, excessive cyanobacteria growth can cause ecological and public health concerns, including producing cyanotoxins.

Additional Resources

CyanoTOX® Version 3.0 is an oxidation calculator designed to help utilities evaluate how treatment adjustments (such as pH, oxidant dose, and contact time) may influence degradation of individual cyanotoxins and some groups of cyanotoxins. The latest version maintains the ability to model the oxidative removal of extracellular toxins under various conditions (3 toxins, 5 oxidants, pH, temp, etc). New in this version is an additional module to model intracellular and extracellular toxins throughout a water treatment plant. New capabilities include release of intracellular toxins, three zones of oxidation, PAC carbon adsorption, settling of solids, biofiltration/GAC and other features. 
 
 

Summer 2021 Webinar Series - Comprehensive Strategies to Protect Drinking Water from Harmful Algal Blooms

The USACE Invasive Species Leadership Team in collaboration with the Aquatic Plant Management Society, North American Lake Management Society, and the American Water Works Association held a series of webinars in June-July 2021 that summarized the latest research and technical information on management strategies to encourage better integration and facilitation in the protection of drinking water.

  • HAB Impacts to Drinking Water and Current Management Outlook
  • Source Water Protection in the Watershed
  • Mitigation of Internal Nutrient Loads in Drinking Water Sources
  • Harmful Algal Bloom Management
Recordings and PowerPoint slides of all webinars can be access at USACE's Natural Resource Management Gateway.

Conferences

 

AWWA Policy Statements

AWWA's policy statements are brief statements on protecting and improving water supply, water quality, management, and the interests of the public and the environment. They are written by consensus, subject to review and comment by AWWA committees, councils, and members. Because they represent AWWA's position on these matters, they are approved by the AWWA Executive Committee of the board of directors.

Technical Committee Engagement

AWWA members are recognized globally for their industry expertise and their generosity in sharing that expertise for a better world through better water. AWWA members participate in committee activities, developing conference programs, writing technical manuals, developing standards, creating educational content and contributing to AWWA publications. Committee members primarily interact through conference calls, emails, and face to face meetings at conferences and events.Access more information on volunteering for an AWWA committee.
