Who We Are

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 volunteers like you. Your voice is essential.

Who We Are

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

• Disaster response for vulnerable populations

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

Who We Are

'Thirty years ago, this river was forgotten. Because we organized, native fish are returning. I bring my grandchildren to witness it.' — Commissioner James

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