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. Learn how you can join.

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 data prevents harm. Now I'm training others.' — Jennifer M., Community Monitor

We believe that nature can heal if we give it the chance. Our 20-year track record shows that grassroots action works.
