Since 1992, Friends of Casco Bay (FOCB) has been collecting scientifically-credible data on the water quality of Casco Bay.   Research conducted by staff and volunteers has added to the fundamental understanding of the health and dynamics of Casco Bay.  The data has been used to promote polllution reduction efforts, restore marine habitats, identify sensitive areas in need of protection or further study, and to inform state regulatory actions.  For example, FOCB data was instrumental in the State reclassification of waters off Peaks and Little Diamond Islands, Two Lights in Cape Elizabeth and Willard Beach from class SC to SB, a higher standard for water quality.

The Water Quality Monitoring Program is not just about collecting data; it also entails recruiting, training, and supporting a valued corps of volunteer "citizen scientists."  Since the inception of the program, more than 400 Citizen Scientists have been trained in U.S. EPA-approved sampling techniques.  Rigorous review of the monitors' techniques and data ensure that the Program accrues reliable information on the water quality of Casco Bay.  Shoreside sampling by volunteers complements the monitoring done by FOCB staff members Peter Milholland and Mike Doan aboard the Baykeeper boats.  They conduct monthly profiles of the water column at ten offshore stations, year-round at times coping with stormy weather, rolling seas, and frozen bays.  CBEP provides funding to support this Water Quality Monitoring Program.
