Our mission is to protect the public’s right to clean water in the Potomac and Shenandoah Rivers and their tributaries. We stop pollution to enhance the safety of our drinking water, protect healthy river habitats, and enhance public use and enjoyment.
With our watershed covering more than 14,000 square miles, our three riverkeepers are working every day to be a voice for our rivers and the best advocates against pollution in the Lower Potomac, Upper Potomac, and Shenandoah.
