Testing tap water for lead
Lead can be toxic. While lead is no longer used in plumbing, some older structures might still have lead piping.
On this page
Homes and buildings in Peel that are at higher risk for lead water pipes are eligible for lead testing.
We’ll test the tap water for lead if your home or business:
- Was built before 1960.
- Has plumbing that’s connected (or you suspect it’s connected) to lead service pipes.
- Might have lead plumbing.
- Might have plumbing or service pipes with lead solder (welding).

Testing for lead in Peel’s drinking water
- Municipal drinking water systems in Ontario are required to monitor lead concentration in water supply through a Community Lead Testing Program.
- We test drinking water for lead in private taps twice a year (in homes and businesses), and in the distribution system (i.e. municipal hydrants) throughout Mississauga, Brampton, and south Caledon.
- Our program results have consistently met provincial drinking water quality standards and Health Canada Guidelines.
- Lead in Peel’s drinking water is well below the acceptable lead level of 10 parts per billion.
- To view a summary of lead results for previous years’ testing and for more information about your drinking water in Peel, visit our Water Quality Reports page.
Elevated lead levels
- If lead levels test above the provincial limit, we investigate the section of the water service pipe that connects the home or business to the watermain.
- If the municipal portion (public side) of the service pipe contains lead, we immediately replace it.
- If we find lead on the private (home or business owner’s) side of the service connection or in the building’s plumbing, we encourage the owner to replace the pipe or to monitor and control the lead levels. Refer to replacing your private side water service for more information.
