Surface Water Ambient Toxics Monitoring Program (SWAT)

Contact: Questions may be directed to authors of each study or to Tom Danielson, 207-441-7430

Maine’s Surface Water Ambient Toxics (SWAT) monitoring program was established in 1993. Its goal is to determine the nature, scope, and severity of toxic contamination in the surface waters and fisheries of the State. SWAT monitors tissue, sediment, and the water column in all waters of the State. This includes monitoring the health of organisms that may indicate toxic conditions. The program collects data to understand the risks to human and environmental health posed by these toxic contaminants.

SWAT data are available through EGAD.
