The New York State Department of Environmental Conservation has confirmed Laurel Lake is safe for swimming.
In May, the Suffolk County Health Department issued a warning to residents and asked them to stay out of the lake since Stony Brook University professors found high levels of cyanobacteria — also known as a blue-green algal bloom — in the water.
DEC spokesperson Lori Severino said the lake tested negative for harmful algal blooms on June 13, adding cyanobacteria is naturally present in lakes and streams.
Not all blue-green algal bloom are toxic and health risks for humans typically occur when they’re exposed to high levels of cyanobacteria, county health officials said.
Waters become unsafe when larger blue-green algal blooms form and produce scum or take on a paint-like appearance, officials said, adding contact with the skin can cause a rash or irritation and swallowing highly-infested water could cause nausea, vomiting, abdominal pain or diarrhea.
