About Us

Water doesn't recognize borders — and neither do the threats it faces. Our regional teams work tirelessly to restore it.

This work is possible because of volunteers like you. Every contribution matters.

About Us

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

• Community science programs for local stewardship

The water that flows through you connects you to 7 billion people — and countless ecosystems. Stand with us.

About Us

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

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to hold polluters accountable.
