EPA Updates! HAB's Research, Resources, and Tools ------- NEWS ON HABs U.S. EPA fs Harmful Alsal Blooms Regional Workshops Summary Report On March 3, 2021, EPA released a summary report of the outcomes and recommendations from a series of workshops held from 2015 to 2019 in nine EPA regions on the protection of public health from HABs in fresh and marine waters. The Office of Water, in coordination with the EPA Regions, brought together HABS experts from federal, state, and local agencies, and representatives from utilities, academia, and other stakeholders to learn and discuss the strategies for managing HABs in drinking water and recreational waters; make connections; and identify shared goals, needs, and barriers among federal, state, and tribal Clean Water Act (CWA) and Safe Drinking Water Act (SDWA) programs. How Do You Respond to Benthic CyanoHABs? The Interstate Technology and Regulatory Council's (ITRC) Strategies for Managing and Preventing Benthic Harmful Cyanobacterial Blooms (BHCB) team is requesting your assistance in determining if and how states respond to benthic harmful cyanobacterial blooms. The BHCB is sharing this survey to learn about the variety of state response capabilities and needs regarding benthic HABs. The team will use information gathered from this survey to target the topics to be covered and resources to be developed in its guidance. If interested, please complete the survey located at https://www.survevmonkev.eom/r/8PVX2L2 by April 2, 2021.

Registration is not required. The webinar will be held 11:30am to 1:00pm EST. More details will be online here. Publication of the 2nd Edition of WHO's Toxic Cvanobacteria in Water On March 8, 2021, the WHO published the 2nd Edition of Toxic Cyanobacteria in Water. This publication presents the current state of knowledge on the occurrence of cyanobacteria and cyanotoxins, as well as their impacts on health through water-related exposure pathways. It also provides information to support the effective assessment and management of the risks posed by cyanobacteria and their toxins. ------- Reported Blooms, Beach Closures, and Health Advisories* - February 2021 includes blooms, cautions, warnings, public health advisories, closings, and detections over state thresholds, due to the presence of algae, toxins, or both. This is not a comprehensive list, and many blooms may have not been reported or lakes are not actively monitored. Vancouver •=> O T . ^ .

(live and virtual) The New York Department of Environmental Conservation (DEC) announces the release of the Harmful Algal Blooms Research Guide, which highlights topics to advance the study, management, and mitigation of HABs in New York. Four research focus areas - Prevention and Mitigation, Causes of HABs, Monitoring and Modeling, and Engagement - are intended to prioritize DEC research efforts and to lay the foundation for HABs research coordination. The initiative included regional HABs summits that led to the development of waterbody-specific HABs Action Plans and targeted mitigation studies ------- Recently Published Articles* Using a lake sediment record to infer the long-term history of cyanobacteria and the recent rise of an anatoxin producing Dolichospermum sp.
