Our Mission

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

This work is possible because of volunteers like you. Learn how you can join.

Our Mission

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

• Long-term scientific monitoring of water quality shifts

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

Our Mission

'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.' — Sarah K., Watershed Advocate

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