As weather warms up, it's important to look out for algal blooms. In our division, we work to prevent these incidents as much as possible by enforcing nutrient pollutant load requirements and educating the public about pollution prevention. In the event that an algal bloom does occur, NC Department of Environmental Quality provides this resource for how to identify and report the issue.
What are some potential clues of a potential harmful algal bloom? Blue-green algae can look like spilled blue or green paint on the water, a floating mat, or scums along shorelines. Another clue is a foul odor.
Testing and analysis are required to confirm the presence of algae that can produce toxins.
Report a bloom online or call your Division of Water Resources regional office.
