FAQs

Frequently Asked Questions

Collecting Your Sample

Do I need a special collection kit if I use the electronic requisition?
You do not need a special collection kit if you use the electronic requisition. If you already have one of PHO's drinking water test collection kits at home, you can use the bottle in that kit to collect a water sample. Alternatively, you can pick up a sterile PHO drinking water collection bottle from your local PHO laboratory, local public health unit, or one of the public health unit affiliated locations in your community. Only a PHO drinking water collection bottle will be accepted by the laboratory.

Who can submit a water sample for testing?
Any individual who relies on private water sources, such as wells, cisterns, or treated lake water, can submit a water sample for testing.
