Harmful Algal Bloom (HAB) issues locally and regionally will be the focus for the next Pennsylvania Lake Erie Environmental Forum (PALEEF), hosted virtually on March 26, 2024, at 1:00PM Eastern. Participation is free but registration is required. The forums are hosted by the Pennsylvania Department of Environmental Protection (PA DEP) and Pennsylvania Sea Grant.

Invited local and regional speakers will come together to discuss the Harmful Algal Bloom issues in Pennsylvania and the Great Lakes Region. The Erie County Department of Health will present about HAB issues in Lake Erie and Erie, PA. The Pennsylvania Department of Environmental Protection will present about HABs in a statewide scope. Guests from the Great Lakes HABs Collaborative will cover HAB issues throughout the basin, and new, innovative research in the HABs space will be touched upon.

HABs are a major threat to Great Lakes and Pennsylvania waters. They can form quickly and produce harmful toxins that impact the skin, livers, and neurological systems of people, dogs, and other animals. Because of their potential danger, HABs can cause declining recreation and revenue generation in the areas they impact. According to the Center for Disease Control (CDC), blooms can become dense, blocking sunlight availability to underwater plants, and clogging the gills of fish, shellfish, and other animals which can prevent them from breathing. When the dense blooms die off, the decay process can use up all available oxygen in the water, causing other organisms in the water to suffocate. Decaying blooms can also release methane and hydrogen sulfide further impacting recreation and water quality (CDC, 2024).

It is imperative that we learn about HABs at local, statewide, and regional levels in order to understand their formation, toxin production, environmental impacts, and possible solutions. Join the Lake Erie Environmental Forum to learn more about HABs through multiple speakers and researchers both locally and regionally.

Participation is free, but registration is required. Contact Amber Stilwell, Pennsylvania Sea Grant’s Lake Erie Coastal Outreach Specialist, for additional details or with questions. The Forum agenda and links to previously recorded sessions are available online.

Pennsylvania Sea Grant is supported by the National Oceanic and Atmospheric Administration (NOAA), Penn State University, and through federal, state, and local funding.
