Start of testing season

Whether you’ve been at it for years or this is your first season water testing, this page will tell you everything you need to know about starting your season on the right foot.

Start of testing season

I went to the Toronto Islands Public school and did some water sampling with three Water Ranger kits with 26 first graders along with several parents and their teacher Biz Arends. This was very exciting for everyone, and the kids were able to learn about the waters right outside their school. The Kits were a great hit, and all the instruments and testing devices were easy to grasp by these young children. The kit was also passed to other grades to see if there were opportunities for old classes to plan for testing the water in warmer weather and doing some scientific studies.
