Our Mission

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. Your voice is essential.

Our Mission

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

• Legal advocacy driving stronger standards

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

Our Mission

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my action prevents harm. Now I'm inspiring others.' — Jennifer M., Watershed Advocate

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to rebuild what was lost.
