The Annual NPS Conference is the premier forum in the Northeast for sharing information and improving communication on NPS pollution issues and projects. Since 1990, NEIWPCC, in partnership with its member states, has been coordinating the event. Conference participants include federal, tribal, state, and municipal government staff, private sector professionals, nonprofit and watershed organization staff, as well as college and university students and professors.

This year’s theme is “Nonpoint Source Pollution and Clean Water: Perspectives from the Arts, Sciences and Humanities.”

The 35th Annual NPS Conference is being held April 9th and 10th, 2025 at the Harraseeket Inn & Event House in Freeport, Maine.
