We are a non-profit organization dedicated to sustainably growing the community water testing movement. Lovingly assembled in Canada and the United Kingdom.

Community-based water monitoring (CBWM) is a cost-effective and scientifically rigorous way to collect data on freshwater quality across watersheds. Water Rangers designs, produces, and manages tools that lower barriers to water quality monitoring and stewardship, including kits specifically designed for educators. Our affordable, easy-to-use testkits monitor key health parameters in fresh and marine waters, providing results right in the field. Our kits are available for purchase through our online store, below. In line with our internal mandate, 25% of our grant-supported equipment goes to Indigenous and underserved communities.
