Confirmed Harmful Algae Bloom (HAB) for Mohawk Bay, Deseronto – August 25, 2020.
The Ministry of the Environment, Conservation and Parks (MECPs) Drinking Water and Environmental Compliance Division has confirmed the presence of a blue-green algal bloom at the Mohawk Bay – and at the Deseronto public boat launch, 183 Main St.
Blue-Green Algae can foul the water and cause smelly water. Several species of cyanobacteria in the algae can create toxins, which pose health concerns. A water sample was taken by the Ministry of the Environment on August 14th, 2020 and analysis confirmed the cyanobacteria in our blue-green algae (specifically: Gloeotrichia, Microcystis). This is a health concern.
The processes of the Deseronto Water and Wastewater Treatment Plant remove the health risk posed by blue-green algae and extra testing is performed starting in June through October to ensure safe drinking water. People are advised to avoid water contact in the Bay and at the Deseronto Boat Launch area.
