Well Water Testing

All Preston Lake residents (private well owners) should test their well water three times each year, in the spring, summer and fall. Well water should also be tested after any repairs / flooding, if the well has been dormant, or if there is a change in water appearance, colour or odour.

Private well water testing is available free of charge. Results from private water tests are sent to the well owner and the local public health office. York Region Health Services public health inspectors are available to assist in the interpretation of the well water results and offer advice on well disinfection, treatment and maintenance through the Health Connection information line (see below).

Water sample bottles are provided free of charge by York Region Health Services. It is recommended to test your water by running your main tap (often kitchen faucet) for 1 minute without any filters (this includes removing the screen at the end of the faucet), prior to filling your bottle.
