“making water quality data accessible…”

“world’s largest water database…”

“taking on America’s water crisis…”

We are the Guardians of H2O.

That’s why we’re building a future where everyone has access to real-time water quality data so they can protect their health. When we gather more hyperlocal data points and build a water quality forecast – the same way meteorologists build a weather forecast – we’ll be able to monitor water quality in real-time, predict (and even prevent!) water-related crises BEFORE people get sick. That will make the world a safer place to live – from your local neighborhood where you live, work and play, to the farthest communities who suffer from insufficient resources and crumbling infrastructure.

You can help us raise the standard of water quality for all. Just by testing your home’s tap water Join us on this journey. Become a Guardian of H2O.

Frequently asked questions

The AquaScore™ is a drinking water quality index based on a 0-100 scale. The higher your score the better. It’s designed to help make it easy for anyone to understand the current state of their local water.

Enter your zip code to find out the score in your area.

The AquaScore™ uses the EPA’s Maximum Contaminant Levels (MLC) in order to evaluate the overall quality of the water.

The contaminant results come from the local public water systems that supply the zip code.
