Sometimes a series of discharges from nonpoint sources results in pollution like Harmful Algal Blooms (HABs). HABs are blooms of Cyanobacteria, also known as blue-green algae, in lakes, rivers, streams, and ponds. They can release toxins at certain times that can make humans and animals sick. HABs are caused by nutrient pollution from things like lawn and farm fertilizers, stormwater runoff, animal manure, detergents, sewers, and malfunctioning septic systems. Learn more about HABs and how to identify and report them in the above video from Michigan Department of Environment, Great Lakes, and Energy.

Take these simple steps to prevent the spread of Harmful Algal Blooms:

• Use phosphate-free detergents

• Properly dispose of pet wastes

• Apply fertilizers only when necessary and at the recommended amount

• Take care to not spread aquatic invasive species while boating and fishing

• Volunteer in local watershed protection efforts
