The Rhode Island Department of Health (RIDOH) and the Rhode Island Department of Environmental Management (DEM) are advising people to avoid contact with Brickyard Pond in Barrington due to a blue-green algae (or cyanobacteria) bloom. Blue-green algae can produce toxins that can harm humans and animals.
Recent consecutive surveys at Camp Hoffman at Larkin Pond in Kingston and Warwick Pond, and associated sample analyses, confirmed that blue-green algae cell counts and toxin levels have been at acceptably low levels. These levels meet state guidelines to support lifting the advisory.
People should be careful not to ingest water or eat fish from areas near Brickyard Pond. All recreation, including swimming, wading, fishing, boating, and kayaking, should be avoided. Animals who may ingest the water are especially at risk from exposure to the algal toxins, so owners should not allow pets to drink or swim in the lake. The advisory will remain in effect until further notice.
Skin contact with water containing blue-green algae commonly causes irritation of the skin, nose, eyes, and/or throat. Common health effects associated with ingesting water containing algal toxins include stomach-ache, diarrhea, vomiting, and nausea. Rarer health effects include dizziness, headache, fever, liver damage, and nervous system damage. Young children and pets are at a particular risk for health effects associated with algal toxins. People who have had contact with pond waters and experience those symptoms should contact their healthcare provider.
If you come into contact with the water, rinse your skin with clean water as soon as possible and, when you get home, take a shower and wash your clothes. Similarly, if your pet comes into contact with the water, immediately wash your pet with clean water. Do not let the animal lick its fur. Call a veterinarian if your animal shows any symptoms of blue-green algae poisoning, including loss of energy, loss of appetite, vomiting, diarrhea, or any unexplained sickness that occurs within a day or so after being in contact with water. People are cautioned that toxins may persist in the water after the blue-green algae bloom is no longer visible.
Blue-green algae blooms can re-occur in affected waterbodies. People are advised to check the appearance of the water before deciding where to recreate. Please avoid contact with waterbodies that exhibit bright green coloration in the water or at the water surface and/or dense floating algal mats that form on the water's surface. Other potentially harmful blooms may look like green paint, thick pea soup, or green cottage cheese.
