The Bangor Area Stormwater Group (BASWG) is a collaboration of members, including Bangor, Brewer, Hampden, Milford, Old Town, Orono, Veazie, Eastern Maine Community College, Maine Air National Guard, University of Maine Augusta – Bangor and University of Maine to use public education and sound science to improve regional water quality through collaborative stormwater management in the Greater Bangor Urbanized Areas.
The Maine Department of Environmental Protection (DEP) routinely tests streams throughout the state to determine the water quality in a stream. When the waters of the stream are determined to not meet their standards, the DEP considers them impaired. There are six Urban Impaired Streams that are within the City of Bangor.
