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

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

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

Every action counts — from small donations to big movements. We can still protect if we move now.

'Thirty years ago, this river was dying. Through their work, native fish are returning. 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 political boundaries to hold polluters accountable.
