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 partners like you. Every contribution matters.

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

The water that flows through you connects you to 7 billion people — and future generations. Stand with us.

'Thirty years ago, this river was forgotten. Because we organized, the ecosystem breathes again. I watch the difference daily.' — Dr. Robert L.

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