Who We Are

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 donations like you. Together we can turn the tide.

Who We Are

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

• Early warning systems of water quality shifts

The water that flows through you connects you to 7 billion people — and billions more organisms. Stand with us.

Who We Are

'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 leading others.' — Sarah K., Volunteer

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