Health Unit issues advisory due to possible blue-green algal bloom at Laurentian University Beach on Lake Nepahwin

The Sudbury & District Health Unit and the Ministry of the Environment and Climate Change are currently investigating a possible blue-green algal bloom at Laurentian University Beach on Lake Nepahwin in Greater Sudbury.

The Ministry of the Environment and Climate Change is testing water samples to confirm the presence of blue-green algae.

As a precaution, the Health Unit has posted signs advising the public to avoid swimming, drinking the water, and allowing pets into the water if the algal bloom is present at the beach. If no bloom is present, water can be used for regular recreational activities.

Blue-green algal blooms could also appear in other parts of affected lakes. Because blooms are not anchored, they can move from one location to another through wind and water action. New blooms can also form. All residents on lakes or rivers should look for blooms in their area.

Blue-green algal blooms have an unsightly pea soup appearance and foul smell, and can produce toxins.

The highest concentrations of toxins are usually found in blooms and scum on the shoreline. These dense accumulations pose the greatest potential risks to people and pets. The algae toxins can irritate a person’s skin and, if ingested, cause diarrhea and vomiting. If a person ingests high levels of toxin, they could suffer liver and nervous system damage.
