Solve pollution problems through voluntary action on the part of the polluter or government

How It Works

  1. EDUCATION: Riverkeepers and outreach staff engage communities that depend on and live near the Potomac and Shenandoah through educational presentations and development of close relationships.
  2. STAKEHOLDER ENGAGEMENT: Our Riverkeepers work with key community members to improve land use practices.
  3. GRASSROOTS CITIZEN ACTION: We call upon citizens to submit public comments and citizen complaints, and connect communities with their local waterways under our River Access & Recreation Program.
  4. BEHAVIORAL REFORM: Our Riverkeepers work with polluters/government agencies to improve practices or regulations that fall short of meeting requirements set forth by environmental laws. Lobby to improve legislation when laws are unable to protect our waters from a particular type of pollution.
