VIDEO: Tools for Addressing the Risks of Cyanotoxins in Drinking Water

U.S. EPA Office of Ground Water and Drinking water recently released a video that provides an overview of available tools to support proactive planning for cyanotoxin management in drinking water; watch the video here.

Many thanks to Dr. Lesley D’Anglada, US EPA, Editor of the Freshwater HABs Newsletter  for sharing this information.


CyanoSED: A Workshop on Benthic Cyanobacteria and Cyanotoxins, August 6 & 7, in Cincinnati, Ohio.

On August 6 and 7, 2018, CyanoSED: A Workshop on Benthic Cyanobacteria and Cyanotoxins will take place at EPA-Cincinnati.

The workshop is organized by Dr. Kaytee Pokrzywinski (U.S. Army Corps of Engineers), Dr. Timothy Davis (Bowling Green State University), Dr. Susie Wood (The Cawthron Institute) and Dr. Jim Lazorchak (EPA, ORD, NERL).

The goals of the workshop are to identify knowledge gaps and prioritize research needs on issues surrounding benthic cyanobacteria and it will feature presentations from experts in the field and discussions on those presented topics.

 Symposium Objectives:

  1. Understand current research in benthic/sediment-associated HABs related to benthic mat-forming (including attached, periphytic and filamentous) cyanobacteria and benthic-pelagic (planktonic) coupling of bloom events.
  2. Identify knowledge gaps and topic areas worth pursing in more detail.
  3. Facilitate engagement among federal, local and state government agencies; academic institutions; and industry partners to continue coordination and collaboration on sediment/benthic-associated HABs issues.
  4. Effectively disseminate workshop results by facilitating publication of research priorities and detailed key discussions developed through this workshop.

This information was shared by Dr. Jim Lazorchak (EPA, ORD, NERL).

CYANOCOST featured in the US EPA “Freshwater HABs” newsletter

The “Freshwater HABs” newsletter issued by US EPA (Dr. Lesley V. D’Anglada) features CYANOCOST in its recent edition (January 2017).

The Freshwater HABs newsletter contains information about many important programs, initiatives, regulations and events in USA and beyond around toxic cyanobacteria, cyanotoxins and the protection of water resources.

The Newsletter features CYANOCOST’s new website and CYANOnews. We warmly thank Dr. D’Anglada and US EPA for creating those links between US and European researchers in Freshwater HABs.

You can download all “Freshwater HABs” newsletters here, or you can contact Dr D’Anglada to sign up for the Newsletter.



This event is hosted by the Health and Ecological Criteria Division in the Office of Water at the United States Environmental Protection Agency. This event is open to the public, but interested parties would include: local, state, and federal public health and environmental agencies that are responsible for the protection of human health while recreating in water.

This webinar will include a presentation on the basic science used in the development of the criteria, a look at implementation considerations, and an opportunity to receive feedback from participants.

Date and Time: Wed, February 15, 2017, 2:30 PM – 3:30 PM EST
