Water Quality Information

After rainfall of 1/2 inch or more, all Anne Arundel County beaches are under a no swimming/no direct water contact advisory for at least 48 hours due to predicted elevated bacteria levels from rainwater runoff and increased health risks.

Every summer the Herald Harbor Citizens' Association partners with Anne Arundel Community College's Operation Clearwater which tests the water quality at our local Bonaparte Beach.

You can find the weekly test results by clicking "Water Quality" in the navigation section of this website, or by clicking here.

You can find more information about when it's safe to swim on the county website.
