About this organization
Building the tools to care for your local waterways.
Water Rangers turned 10 in 2025! For the past decade, we’ve worked with passionate individuals and groups dedicated to taking care of our most precious resource, water. We imagine a world where every waterbody’s community has the tools they need to take care of them. Plus, every lake, river, or stream should have enough data to know whether or not they are healthy.
Our ability to design beautifully integrated water testing experiences means that our tools are easy-to-use and accessible. That means custom water quality testkits, an open-data platform to manage data, and specially designed resources so that anyone can get started.
