The Future of Water

is in Your Hands

We imagine a world where you have real-time water quality information and how it impacts your health-now when you need it-not after an entire communities get sick. That's why we need your help!


Americans are being impacted by some form of water contamination.


You use an average of 80-100 gallons of water throughout your day. Could your water be impacting your health?


Americans are impacted by toxins in their tap water. Are you one of them?

Important Facts

Local Data. National Impact.

We're scanning millions of water quality data points so you don't have to. Help us make real-time water quality monitoring a reality for communities everywhere.

Using technology to prevent the greatest threat to out existence on the planet. Ever.


By 2030 there will be a 40% greater demand for cleaner water. According to the United Nations, by 2030 there will be a 40% greater demand for clean water than there is supply on this planet for the first time in human history.


We simply cannot survive that.
But we're not going to just sit back and watch it happen. Guardians are stepping up, leaning advanced technologies like data science, machine learning, and software engineering skills to help create innovative solutions and extend the life of the planet.

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.
