Our Work

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

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

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

The water that flows through you connects you to 7 billion people — and future generations. Stand with us.

'Thirty years ago, this river was polluted. Thanks to this organization, native fish are returning. I watch the difference daily.' — Professor Chen

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across generations to hold polluters accountable.
