Our Work

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 volunteers like you. Every contribution matters.

Our Work

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

• Policy research driving justice

The water that flows through you connects you to 7 billion people — and future generations. Join the fight.

Our Work

'Thirty years ago, this river was forgotten. Because we organized, the ecosystem breathes again. I bring my grandchildren to witness it.' — Elder Maria

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