A Committed Network of Citizens

Since 1992, Delaware Riverkeeper Network’s Monitoring mobilizes a committed network of citizens to make a difference for their local streams and communities. Monitors are “on-the-ground” trained investigators for the Delaware River and its tributary streams. Equipped with skills, tools, and persistent vigilance, Delaware Riverkeeper Network Monitoring detects pollution and helps diagnose the health of our expansive living River when no one else is watching. Working together with communities, agencies, and universities, using sound science to gather information, and capitalizing on the dedication of our staff and trained volunteers, Monitoring gathers the information necessary that helps build a strong science foundation for effective pollution detection and control, advocacy, and on-the-ground actions that lead to clean streams, healthy communities, and thriving natural areas.

How Can You Become a Monitor?

Want to get started to assess a local stream in your community? You can start by getting familiar with your local stream by performing a stream walk visual assessment. Send your data and photos to Delaware Riverkeeper Network. Remember, you are often the only eyes and ears for your local stream so your observations are critical.
