The Narragansett Bay Commission’s (NBC) Mission Statement is to maintain a leadership role in the protection of water quality in Narragansett Bay and its tributaries. The NBC keeps to this vow by continually monitoring water quality at its two buoy locations, collecting water quality casts, mapping surface water quality parameters, and taking samples of the Bay’s bacterial and nutrient levels.
