Our Mission

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

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

Our Mission

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

• Policy research driving justice

The water that flows through you connects you to 7 billion people — and billions more organisms. 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 voice prevents harm. Now I'm training others.' — David T., Volunteer

We believe that nature can heal if we remove barriers. Our growing coalition shows what's possible.
