Charles River Wins Prestigious International Award
A River Reborn: From Pollution to Prize
October 2011 marks a watershed moment for Boston’s Charles River. For the once-polluted waterway most notably clinches the 2011 Thiess International Riverprize. This accolade, bestowed by the International River Foundation, recognizes outstanding achievements in river management and restoration.
Charles River Cleanup: Decades of Dedication Pay Off
The transformation spans nearly two decades. Since 1995, a coalition of federal, state, and local entities has worked tirelessly to revitalize the river. In addition, their efforts focus on reducing pollution. Moreover and also improving water quality.

Measurable Success in Water Quality
For starters, the river’s health shows remarkable improvement. In 1995, the Charles met boating standards only 39% of the time and also swimming standards a mere 19%. Fast forward to 2010, and these numbers skyrocket to 86% for boating and 66% for swimming.
A Model for Global River Restoration
Matthew Reddy, CEO of the International River Foundation more notably lauds the achievement. He states, “Charles River joins the ranks of iconic rivers like the Thames, Danube, and Mekong.” This recognition places Boston’s backyard river on the world stage of environmental success stories.
Collaborative Efforts Drive Progress
The Charles River Watershed Association (CRWA) accepts the award in Brisbane, Australia. However, the victory belongs to a broad coalition. For starters, the U.S. Environmental Protection Agency, Massachusetts Department of Environmental Protection, and local municipalities all play crucial roles in the river’s restoration.
Challenges Remain Despite Progress
While bacteria levels have decreased significantly, nutrient pollution remains a concern. Phosphorus levels, in particular, continue to pose challenges for the river’s ecosystem. Ongoing efforts target this issue to further improve water quality.
Looking Ahead: A Swimmable Charles
Finally, the ultimate goal of a fully swimmable Charles River inches closer to reality. As cleanup efforts continue, the river’s future looks brighter than ever. For this international recognition serves as both a celebration of progress and a call to continue the vital work of river restoration.
