Boston area beaches are managed by local municipalities or the Mass. Department of Conservation and Recreation (DCR). MWRA assists DCR with summer bacterial testing of beaches. Download monitoring data from the Harbor, rivers, and beaches.

Water quality alerts for all DCR designated swimming areas are posted online in real-time on the park alerts dashboard.  We encourage you visit to check for any postings before your swim.
