Ontario: Borrow a Freshwater Explorer Testkit


Please note: The borrowing program is relaunching in mid-May. If you’d like to borrow a testkit before then, please email kat@waterrangers.ca. 

Want to dip your toe into the wonderful world of citizen science? By borrowing a kit, you get to try out Water Rangers without the full testing program commitment.

What are Testkits? Testkits are a fun way to learn about water and bring communities and families together. We don’t require you to take samples to a lab! The tests are done right away, and the results are immediate! If you’re already convinced and don’t need to try out our lending program you can visit our store at anytime to order your kit: You can buy your own kit in our store. Please note: these tests do not determine if water is safe to drink or swim in.

How does borrowing a kit work exactly? Subject to availability, you choose your pick up/drop off location and the period for which you want to lend the kit (up to 12 days).

What if I can’t make the drop-off date?  Kits must be returned on time otherwise a late penalty of $5/day will be enforced.

Do I need any training? No previous experience is necessary! We will provide you with a field guide, video tutorials, and a quick start guide. Then take your kit out onto the water to try it out and teach your friends and family how to use it too!

Can anyone sign up for this program? We do not have restrictions on who can sign up for the program but we strongly encourage you to read through our terms before making your booking. While most of our tests can be conducted by children with supervision, we recommend that only children 10+ years old perform the dissolved oxygen test. You can see our terms of use here: http://store.waterrangers.ca/borrowing-terms/

How accurate is this kit? This kit has also been compared to professional probes by Carleton University with good results: Read the report.

If a friend/family member has booked the kit right after me, do I still need to return it to the drop off location? Yes! Before each new booking we check the kit to make sure everything is in working order and stocked properly. However, you can always email us to ask. Just email us at testkits@waterrangers.ca.

This program is made possible by the City of Ottawa’s Community Environmental Projects Grants Program
