Potomac Named Most Endangered River

American Rivers named the Potomac River, known as ‘the nation’s river’ as it flows through the capital, the most endangered in the country. While the Potomac is cleaner than it used to be, the river is still threatened by urban and agricultural pollution– and it could get much worse if Congress rolls back critical clean water safeguards.

Take Action:
- Be a Potomac Advocate. Keep up on important issues for the lands and waters of the Potomac.
- Write your member of Congress to Stop the Continued Attacks on Your Clean Water. Congress must stop the ongoing attempts to weaken the Clean Water Act or prevent the Environmental Protection Agency and the U.S. Army Corps of Engineers from restoring protections for small streams and wetlands under the Act.

Potomac Health Weakens as Population, Development Increase

Potomac Conservancy released its fifth annual State of the Nation’s River report, scoring the rivers’ health at a barely passing “D” grade, a downgrade from our previous D+. The report points to reasons for the low grade: growing population and land use practices as the primary culprits for a polluted and degraded Potomac River.
This new Conservancy report compares the western, undeveloped, reaches of the Potomac River region to the more urbanized sections, east and south. Evidence points to population increases and poor development practices as primary sources of stress on the Potomac River, at a regional and local scale.
Conservancy forum talks about new pollutants

Potomac Conservancy hosted science, policy, and technology experts for an important discussion about how to protect the health of our rivers and streams in light of endocrine disrupting compounds (EDCs) and other emerging contaminants that are present in our waterways.
Here are links to media coverage of the event:
