We are organized around the core principle of service to, and collaboration with, our seven member states—Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont—each of which pays annual dues to be a part of NEIWPCC.

In addition to region-wide work at our Lowell, Massachusetts, headquarters, NEIWPCC manages or supports programs and environmental training in its seven member states. Many programs focus on a particular watershed or area.

Additional NEIWPCC employees work in state offices across the region.

Long Island Sound Study

The Long Island Sound Study Program runs and funds research, monitoring, mitigation, and public outreach programs that protect the sound.

Massachusetts Training

NEIWPCC trains and accredits wastewater operators and soil and septic inspectors in Massachusetts.

Maine Training

NEIWPCC’s JETCC program trains and accredits wastewater operators in the state of Maine.

Lake Champlain Basin Program

The Lake Champlain Basin Program runs and funds research, monitoring, mitigation, and public outreach programs that protect the lake.

Hudson River Programs

In the Hudson Valley, two linked programs run and fund research, monitoring, mitigation, and public outreach programs that protect the Hudson estuary watershed.

As an interstate commission, established by an Act of Congress in 1947, NEIWPCC has some jurisdiction over the waters of New England and New York.

Watersheds do not always fit neatly within state boundaries, and there are many environmental similarities across our member states.

NEIWPCC engages and convenes water quality professionals and other stakeholders across the Northeast to collaborate on clean water and environmental science challenges across shared regions, ecosystems, and areas of expertise.
