Frequently Asked Questions
How was the Charles River cleaned up?
The Charles River was once so polluted that the Standells’ 1966 song “Dirty Water” became its anthem. A massive cleanup effort beginning in the 1990s transformed it — today the river earns an A grade for water quality. The EPA’s Clean Charles Initiative is considered one of the most successful urban river restorations in the US.
