Harmful bacteria can be found in our rivers. These bacteria pose a human health risk, and West/Rhode Riverkeeper monitors bacteria levels to inform our community of that risk. Bacteria come from a variety of sources, including failing septic systems, sewer overflows or leaks, pet waste, and livestock. During significant rainfalls, the possibility always exists for elevated and unsafe bacteria levels.

Note: The Anne Arundel County Health Department advises that after a rainfall, all Anne Arundel County beaches are under a no swimming/no direct water contact advisory for 48 hours due to predicted elevated bacteria levels from rainwater runoff and increased health risks.
