Finding water pollution, figuring out the source, developing a solution.

How It Works

Through citizen reports and staff monitoring, we investigate pollution incidents and ongoing threats to water quality. Once a major pollution threat is identified we implement measures to find a solution.

  1. PATROLLING: Staff and volunteers conduct regular On-The-Ground and On-The-Water investigations to hunt for pollution.
  2. CITIZEN POLLUTION REPORTS: Our Riverwatcher Program trains interns and citizens how to identify and report pollution in our watershed.
  3. COMPLIANCE SWEEPS: We conduct systematic, bi-annual compliance sweeps to determine what point-source polluters are exceeding their Clean Water Act (CWA) Permits.
  4. SCIENTIFIC RESEARCH: Working with partners, we research and assess the current state of our rivers.
