The Great Swamp Watershed Association (GSWA) actively monitors the water quality in the Passaic River Region throughout the year. Our Water Quality Testing Program annually samples 21 locations to assess various chemical parameters. We invite you to join our “Stream Team,” which meets a few times each year. New members, aged 15 and older, are always welcome. We offer public stream assessment training sessions each spring and fall. Explore our Volunteer Opportunities to help us thrive!
