  Water Test at Monee Reservoir Shows Algae Bloom Non-Hazardous

On July 28 and August 4, the Forest Preserve District tested the lake water at Monee Reservoir for hazardous toxin (microcystin) concentration levels resulting from a recent algae bloom. Both tests showed that at this time, the lake water microcystin concentration is well below levels considered hazardous by the World Health Organization.

Algae blooms are temporary and are natural seasonal events that occur in some water bodies, and not all are capable of producing microcystins. Exposure to high levels of microcystins may cause health concerns if they are ingested or if they come into contact with sensitive individuals, children and pets. When the bloom is no longer present, the potential health risk will also go away. The Forest Preserve will continue to monitor the situation and will keep the public informed of any new developments. Additional testing will be done periodically.

As a general rule, however, it is always good practice to avoid coming into contact with any algae that is visible on the surface of the water. If contact is made, wash your skin thoroughly as a precaution. Do not let pets drink or swim in the water. If pets come into contact with algae, rinse them off before they lick their fur.
