Impact

Our work begins where rivers meet the sky and ends where groundwater feeds the soil. We use partnerships to protect it all.

This work is possible because of partners like you. Learn how you can join.

Impact

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We predict risks so communities can act.

• Long-term scientific monitoring of water quality shifts

The water that flows through you connects you to 7 billion people — and countless ecosystems. Protect it with us.

Impact

'Thirty years ago, this river was polluted. Because we organized, children can swim safely. I watch the difference daily.' — Commissioner James

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across generations to solve problems at their source.
