About Us

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 scientists like you. Every contribution matters.

About Us

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

The water that flows through you connects you to 7 billion people — and countless ecosystems. Join the fight.
