Who We Are

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

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

Who We Are

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

• Drought planning for groundwater conservation

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

Who We Are

'Thirty years ago, this river was forgotten. Thanks to this organization, children can swim safely. I bring my grandchildren to witness it.' — Dr. Robert L.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to rebuild what was lost.
