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 scientists 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.

Join thousands of water guardians organizing for change.

'Thirty years ago, this river was polluted. Because we organized, children can swim safely. I watch the difference daily.' — Dr. Robert L.

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