WORCESTER – The City of Worcester announced on Thursday the reopening of Coes Reservoir and John J. Binienda Memorial Beach after test results confirmed cyanobacteria and cyanotoxins concentrations in the water don’t pose a threat to public health.
On July 20, the City identified scum along the shoreline at Coes Reservoir. The cyanobacteria in it was identified as the genus Aphanizomenon, which has the capacity to produce toxins.
The reservoir was treated with an algaecide on July 22 and further testing of the water confirmed that cyanobacteria and toxins were not present in harmful concentrations.
Cyanobacteria are naturally occurring, but can be harmful in high densities. If you or your pet has had contact with surface scums, wash off with freshwater immediately. If your pet has ingested any of the scums, contact your vet.
The City has an active cyanobacteria monitoring and management program intended to keep our lakes safe for recreation and wildlife.
John J. Binienda Memorial Beach at Coes Pond is open to the public daily from 12 PM to 7 PM.
