Beaches in Boston Harbor are managed by local municipalities or the Mass. Department of Conservation and Recreation (DCR). MWRA assists DCR with daily bacterial testing of five urban beaches in summer. All other Boston Harbor beaches are tested weekly.

Daily updates on the bacterial water quality at Harbor beaches can be accessed by calling DCR's telephone hotline at 617-626-4972.
