RIDOH recommends lift on Slack Reservoir algae restrictions
PROVIDENCE, R.I (WLNE) – The Rhode Island Department of Health and the Rhode Island Department of Environmental Management (DEM) have released a statement recommending a lift on the restrictions to recreational activities at the Slack Reservoir in Smithfield and Johnston.
The advisory was related to high levels of blue-green algae (cyanobacteria) found in the water, which can produce harmful toxins to humans and animals upon contact.
According to RIDOH, recent consecutive surveys and sample analysis confirmed an acceptably low presence of blue-green algae and that cyanotoxin is not present in detectable concentrations.
These findings meet the advisory guidelines and support lifting the advisory.
RIDOH recommends that the public avoid contact with any body of water that is bright green or has floating algal mats on the water’s surface, which may look like green paint or thick pea soup when visible.
Toxins may persist in the water even after blue-green algae is no longer visible.
