Give Today

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 volunteers like you. Your voice is essential.

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

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

'Thirty years ago, this river was forgotten. Through their work, children can swim safely. I watch the difference daily.' — Elder Maria

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