About Us

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

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

About Us

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

• Corporate accountability driving stronger standards

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

About Us

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

We believe that nature can heal if we remove barriers. Our growing coalition shows that change happens.
