Blue-Green Algae Found In Upper, Lower Melville Ponds

PORTSMOUTH, RI — Toxic blue-green algae blooms were found in two Portsmouth ponds, the Rhode Island Department of Health said. The department asked the public to avoid all contact with both Upper and Lower Melville Ponds, including fishing, boating and kayaking.

Blue-green algae, also known as cyanobacteria, produce toxins that can be harmful to both people and pets. Contact can cause skin, nose, eyes or throat irritation, while ingesting affected water can cause stomachache, nausea or diarrhea. Young children and pets are at the most risk of getting sick.

Blue-green algae blooms can produce toxins that are harmful to both people and animals, especially children and small pets. Toxins can remain in the water even after the algae bloom is no longer visible.

The department encouraged anyone who comes in contact with the toxic water to rinse their skin with clean water as soon as possible. Once home, take a shower and wash your clothes. If you pet comes into contact with the water, do not allow them to lick themselves clean. Wash them with clean water as soon as possible and monitor for signs of illness for the next few days.

The Department of Environmental Management asked Rhode Islanders to keep an eye out for algae blooms in other bodies of water. Blooms can appear as a bright green color in the water or at the surface, a dense mat floating on the surface or water that looks like green paint, thick pea soup or green cottage cheese.
