Drinking Water Lead Testing

Twice annually, the Region of Peel tests drinking water for lead at private taps and municipal hydrants throughout Mississauga, Brampton, Bolton, and south Caledon. To date, the results of this Community Lead Testing Program have consistently met provincial drinking water quality standards and Health Canada Guidelines.

In the rare event when lead is detected above the provincial limit, the Region of Peel investigates the municipal portion of the water service pipe connecting the house/building to the watermain; if it contains lead, it is immediately replaced. If lead is found on the private (home or business owner’s) side of the service connection or within the building’s plumbing the owner is encouraged to consider replacing the pipe or take appropriate action to monitor and control the lead in their drinking water.

For more information visit replacing your private side water service.

This is an ongoing program, and we would appreciate your help. Let us test your tap water for lead, at no cost to you.

For the testing, we require access to the tap used for drinking water for approximately 45 minutes, during which time no water can be used throughout the house/building. Test results will be shared with you directly.

Locations most needed for this program are homes and businesses that:

  • were built prior to 1960
  • have plumbing connected or suspected to be connected to lead service pipes
  • may have lead plumbing
  • may have plumbing or service pipes with lead solder (welding)

To sign up for a lead test at your tap, contact us at 905-791-7800, ext 4685 or email us stating you want a lead test.
