The EPA Office of Water partnered with Region 10 to do a Harmful Algal Blooms (HABs) Workshop on March 29, 30 and 31st in Seattle, Washington. The purpose of the workshop was to bring together Federal, States and Tribal government agencies working on HABs-related issues in freshwater and coastal waters to discuss issues related to harmful algae trends, guideline development, and potential effects of HABs on human and animal populations. In addition, the workshop discussed monitoring tools to predict HABs and an overview of tools aimed at preventing, reducing, and managing HABs in the Northwest (AK, ID, OR and WA). The workshop also provided a venue for participants to learn about existing collaborations with partners nationally and regionally.
