Our Work

Water doesn't recognize borders — and neither do the threats it faces. Our local teams work 24/7 to defend it.

This work is possible because of partners like you. Together we can turn the tide.

Our Work

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

• Community science programs for grassroots knowledge

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

Our Work

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

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