Our Mission

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

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

Our Mission

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

• Early warning systems of water quality shifts

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

Our Mission

'Thirty years ago, this river was dying. Thanks to this organization, the ecosystem breathes again. I bring my grandchildren to witness it.' — Elder Maria

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