Region 5 Harmful Algal Bloom Clean Water Act/Safe Drinking Water Act Workshop and Public Meeting Chicago, IL

The U.S. Environmental Protection Agency's Office of Water, along with EPA Region 5, conducted a Harmful Algal Blooms (HABs) Workshop on April 27th and 28th, 2016, in Chicago, Illinois. The goals of the workshop were to:

  • Share information and build relationships among federal, state and Tribal Clean Water Act and Safe Drinking Water Act programs in Region 5 by making connections and identifying shared HAB-related goals, needs, and barriers, particularly as they relate to source water protection.
  • Identify short- and long-term next steps and key actions that federal, state and Tribal programs can take to address common HAB-related goals, needs and barriers.
  • Facilitate further engagement and shared learning post-workshop with continued engagement among participants.

The workshop was structured to incorporate presentations by subject matter experts followed by discussions amongst participants to share lessons learned from their experiences in both drinking water and ambient water on topics such as: monitoring, analyzing, predicting, preventing, and treating HABs, as well as evaluating the health and ecological effects of HABs and communicating these health risks to the public.
