The Rhode Island Department of Health (RIDOH) and the Rhode Island Department of Environmental Management (DEM) recommend lifting the advisory restricting recreational activities at Barney Pond in Lincoln. The advisory related to high levels of blue-green algae, also known as cyanobacteria, and associated toxins.
Recent consecutive surveys and sample analysis confirmed that blue-green algae has been at acceptably low levels and that cyanotoxin is not present in detectable concentrations. These findings meet State guidelines to support lifting the advisory.
Blue-green algae conditions can change quickly, and it is possible that blooms may affect Barney Pond again, as well as other waterbodies in Rhode Island. The public should avoid contact with any body of water that is bright green or has a dense, floating algal mat on the water's surface. Blue-green algae blooms may look like green paint or thick pea soup. Toxins may persist in the water after a blue-green algae bloom is no longer visible.
