Private Well Water Testing

York Region provides water sample bottles, forms and information to local residents who own private wells  and want to ensure their water is safe to drink. Sample bottles are available for pick up and drop off at several locations. Samples are sent to Public Health Ontario Laboratories to be tested for bacteria. Results of the water test can be received by telephone, mail or can be picked up directly from the Public Health Ontario Laboratories. 

Well water should be tested regularly for bacteria. It is the owner’s responsibility to maintain and monitor their well. See the frequently asked questions for more details.
