Water Quality Monitoring

Citizen Stewards Water Quality Monitoring Program

Each year, dozens of volunteers collect data on water quality in Casco Bay. Trained in EPA-approved techniques, these Citizen Stewards collect samples at 40 sites around Casco Bay.

Supplementing the sampling and research work done by our staff, our volunteers collect baseline data on salinity, dissolved oxygen, temperature, pH, water clarity and nutrients. Together, our staff and volunteers have collected nearly 250,000 water quality measurements since 1992, making our data set one of the most comprehensive and reliable in Maine. This data is critical as Friends of Casco Bay works with businesses, municipalities, and decision-makers around the Bay to find effective ways to curb pollution.
