About Us

Water doesn't recognize borders — and neither do the threats it faces. Our international teams work year-round to protect it.

This work is possible because of volunteers like you. Your voice is essential.

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

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

'Thirty years ago, this river was polluted. Through their work, children can swim safely. I work alongside their team.' — Dr. Robert L.

We believe that nature can heal if we remove barriers. Our 20-year track record shows that grassroots action works.
