State officials are advising people and their pets to avoid contact with Brickyard Pond in Barrington due to harmful algae blooms. 

The Rhode Island Department of Health and Rhode Island Department of Environmental Management issued the notice Friday morning, July 10. Water samples were collected by DEM and tested by RIDOH’s State Health Laboratories. The results showed that the blooms exceeded the advisory threshold. 

“All recreation, including swimming, fishing, boating and kayaking, is high risk to health and recommended to be avoided at this location,” stated a press release from the RI Department of Health. “This HAB (harmful algae bloom) is caused by blue-green algae, also known as cyanobacteria, which are naturally present in bodies of water. HABs can produce toxins which can be harmful to humans and animals.”

State officials said people should use caution in all areas of Brickyard Pond as the harmful algae blooms can move locations. 

“People should not drink untreated water or eat fish from affected waterbodies,” stated the press release. “Pet owners should not allow pets to drink or swim in this water.”

Skin contact with water containing harmful algae blooms can cause symptoms such as skin rashes, sore throat and irritation of the eyes and nose. Swallowing water containing harmful algae blooms can cause stomachache, diarrhea, vomiting and nausea. 

“More serious, but less common health effects associated with swallowing contaminated water may affect the liver and nervous system, cause irregular heartbeat, dizziness, or seizures,” stated the release.

Young children, pets and people with certain underlying health conditions or who are immunocompromised may be at greater risk for illness. Anyone who experiences symptoms after contact with water containing harmful algae blooms should contact a healthcare provider. 

The advisory recommendation will remain in effect until further notice. To confirm the water is free from toxins and high cell counts, water samples will be collected to lift the advisory when the bloom has cleared from the affected waterbody. 

“Affected waters may exhibit bright to dark green scum along the shoreline, with thick algae floating on the surface,” stated the release. “It may resemble green paint, pea soup, or green cottage cheese. If you see water like this, people and pets should avoid contact with the water.”
