About Us

Our work begins where rivers meet the sky and ends where groundwater feeds the soil. We use community power to protect it all.

This work is possible because of scientists like you. Learn how you can join.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to solve problems at their source.

Join thousands of water guardians pushing back for justice.

'Thirty years ago, this river was polluted. Thanks to this organization, children can swim safely. I work alongside their team.' — 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.
