Volunteer

Our work begins where rivers meet the sky and ends where groundwater feeds the soil. We use science to protect it all.

This work is possible because of volunteers like you. Your voice is essential.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across generations to hold polluters accountable.

• Emergency support for vulnerable populations

The water that flows through you connects you to 7 billion people — and billions more organisms. Join the fight.

'Thirty years ago, this river was polluted. Because we organized, the ecosystem breathes again. I bring my grandchildren to witness it.' — Commissioner James

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