Since 1990, NEIWPCC, in partnership with its member states, has been coordinating the Annual Nonpoint Source (NPS) Pollution Conference, the premier forum in our region for sharing information and improving communication on NPS pollution issues and projects. This year’s conference is being coordinated in conjunction with NHDES and EPA Region 1.
The conference brings together all those in New England and New York State involved in the management of NPS pollution, including participants from state, federal, and municipal governments, the private sector, academia, and watershed organizations.


The Call for Abstracts is now closed.
