What You Can Do
Harmful algal blooms are a major environmental problem across the United States. Red tides and toxic cyanobacteria blooms are examples of HABs that can impact human health, aquatic ecosystems, and the economy.
Harmful algal blooms can produce dangerous toxins that can sicken or kill people and animals (livestock or pets), create low oxygen/dead zones in the water, threaten access to water and/or raise its treatment costs, and hurt industries that depend on clean water.
We can all take action to reduce some of the factors that promote the formation and persistence of HABs (e.g. nutrients), learn to identify and report their occurrence and associated illnesses to the appropriate agencies, and help to educate and create public awareness.
Help prevent HABs by reducing nutrient loading into waterbodies
Simple actions around your home and yard can reduce nutrient loadings into waterbodies and can make a big difference.
Volunteer to monitor waterbodies for algal blooms
Report suspected algal blooms to your local and/or state agencies
State departments of health or environment are the best sources for local information about harmful algal blooms and many have apps you can use to report a suspected bloom.
Educate and create public awareness of HABs and their sources
Learn about HABs and use the resources available - e.g. photos and videos- to communicate their associated risks, minimize exposure, and help with reporting.
