We design and sell water quality testkits

Our testkits are built for communities, schools, and passionate individuals who want to learn about the health of local lakes, rivers, or other waterbodies! We have tested them against professional equipment to make sure you get accurate tests in the field without a lab.

Accessible water testing

We're a non-profit organization, and our goal is to provide people with water testing tools and resources that are accurate, affordable, and easy-to-use. All of our tests give results right away for parameters we're sure are as accurate as possible. That means that there are probably a few tests you wish were in our kits (we do too!), but we won't include certain tests in our kits until we're sure they're accurate and safe.
