Our Work

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

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

Our Work

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

• 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.
