Who We Are

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 community members like you. Every contribution matters.

Who We Are

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

• Corporate accountability driving stronger standards

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

Who We Are

'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.' — Michael O., Water Guardian

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