Harmful Algal Blooms & Cyanobacteria
Most species of algae are not harmful, but sometimes certain types bloom in excessive amounts and can cause harm to human and pet health, aquatic ecosystems, and local economies. These harmful algal blooms (HABs), usually associated with algae that produce toxins, cause problems across the Nation.
Sometimes HABs are referred to as red tides, but this can be misleading since they can be different colors. Also, even though they are classified as bacteria, cyanobacteria—sometimes referred to as blue-green algae—exhibit characteristics of algae and are associated with HABs. EPA researchers are looking for ways to eliminate or reduce the negative effects of HABs on human health and the environment.
