The Delaware River runs from the base of the Catskill Mountains to the Delaware Bay. The Delaware Riverkeeper Network (DRN) is a nonprofit organization working in New York, New Jersey, Pennsylvania, and Delaware to help protect and restore the Delaware River and its tributary watersheds. The DRN is involved in advocacy all along the Delaware's watershed. Their web site describes how you can become a member of the network, or a student intern or volunteer. The Delaware Riverkeeper since 1996 is Maya K. van Rossum, who received her Juris Doctor degree from Pace University School of Law; and a Masters of Law degree in Corporate Finance from Widener University School of Law.
