The Great Swamp Watershed Association (GSWA), located in Harding Township, NJ, is the nonprofit member-supported environmental organization that monitors and protects water quality, and investigates and participates in land use issues in the watershed community, while working to strengthen environmental regulations in New Jersey. GSWA also provides environmental education to community groups, teachers and students to help everyone understand the important role we each play in protecting our drinking water and preserving the natural beauty of our environment.
The mission of GSWA is to protect water and land in the ten towns served by the Great Swamp watershed for the benefit of present and future generations. These ten towns are: Bernardsville, Bernards Township, Chatham Township, Harding Township, Long Hill Township, Madison Borough, Mendham Borough, Mendham Township, Morristown and Morris Township.
Formed in 1981 by a small grass-roots group of concerned citizens, GSWA has grown to 2,200 members in over 40 New Jersey municipalities. Although the organization's work is centered primarily within the towns physically located in the watershed, the results of this work extend to the more than one million people who obtain their drinking water from the Passaic River.
We are a non-profit, member-based, 501(c)(3) organization with a staff of eight. In addition to our generous member donations, we are supported by local and national foundations and our Corporate Council.
