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 kit along to the Toronto Island SUP, for a day on the lagoon. The kit fits easily on the board and this allows you to take water samples from places other than the shoreline. All the instrument were easy to use even on a moving board.
