Our Work

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

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

Our Work

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

• Invasive management to prevent extinction

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

Our Work

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my action prevents extinction. Now I'm inspiring others.' — Michael O., Community Monitor

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to solve problems at their source.
