Harmful Algal Blooms and Health

Harmful algal blooms are the rapid growth of algae or cyanobacteria in water that can harm people, animals, or the environment. Going in or near water with a harmful algal bloom can make you sick and be deadly for pets. Harmful algal blooms can discolor water and look like foam, scum, mats, or paint on the surface of the water. They can also grow underneath the water, making some harmful algal blooms hard to see. Stay out of water if it has a swimming advisory or looks or smells bad. For more information, visit: This video can also be viewed at
