About Us

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.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to rebuild what was lost.

Join thousands of climate leaders fighting for change.

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

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