Tools for community water monitoring

We're a non-profit organization building tools to help local communities, governments, and academics organize water monitoring programs for your local lake, river, or ocean. We've designed easy-to-use water quality testkits, an open data platform and training resources to help your community set up your own water quality monitoring program. Originally from Canada. Now, we're in the UK!

How's your water quality?

Did you know? According to WWF's Watersheds Report, over 60% of Canadian subwatersheds are so data poor, we don't even know if they're healthy or not. That's where you come in. We need your help to fill data gaps! We believe that crowdsourcing water quality data through community water monitoring is a great way to help scientists fill in gaps to achieve sustainable water monitoring.

Thank you to our supporters!

Water Rangers' impact would not be possible without the generosity of our funders and supporters.

I took a test kit along to the Toronto Island for a day on the lagoon. The kit fits easily on a paddleboard and this allows you to take water samples from places other than the shoreline. All of the instruments were easy to use, even on a moving board!
