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 30 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. 

 

Join Our Team!

Interested in joining the ranks of our volunteers who sample water quality at sites around the Bay?  Volunteers are trained in rigorous EPA-approved sampling methods and collect samples twice per day on 10 selected Saturdays.  To get involved, fill out our volunteer application and send it to Peter Milholland, volunteer coordinator, at pmilholland@cascobay.org.  You may also call Peter at 207-799-8574 ext. 207.

What are our volunteers like?  Each year, we recognize those Citizen Stewards who have reached 15-year, 10-year, and 5-year milestones in water quality monitoring.  Read bios of our most recent award winners, here.
