For centuries, the Potomac has been an anchor for our region's identity – and the source of 90% of its drinking water. The wildest river running through an urban area, it is home to more than 200 rare species and natural communities. But rapid population growth – and associated urban sprawl – has led to an increase in river and stream pollution. Potomac Conservancy provides effective, long-term conservation solutions: permanently protecting land from development (thereby preventing future pollution), and building a coalition of advocates for smart urban growth and river-friendly policies. Thousands of volunteers in its Community Conservation program engage in hands-on restoration, raise awareness, inspire action, and encourage their friends and family to get involved. Tree plantings, river cleanups, seed collections, and other hands-on activities improve the local environment and empower individuals to leave a healthier, cleaner legacy for generations to come.
