Lead
Testing for lead in water is mandated under schedule 15 of Ontario Regulation 170/03: Drinking Water Systems.
The City of Greater Sudbury, like other municipalities in Canada, tests for lead in the distribution system during two set time frames mandated by the government to ensure the water being supplied is within provincial guidelines.
Lead is not found at elevated levels in City of Greater Sudbury reservoirs or distribution systems. However, it may be possible to have higher levels in household taps.
How can lead-contaminated water exist in my home?
Lead pipes, solder, and some fixtures in household plumbing can introduce lead in the water by a leaching affect. Lead that is present in household plumbing can cause the tap water to have increased residuals if water sits stagnant for long periods of time.
- In homes built before 1955, lead pipes may have been used to bring water from the property line to the house. The National Plumbing Code restricted the use of lead in household plumbing in 1989; however, it may still be available in some hardware stores.
- Any fixture or fitting made of metal alloys such as brass or bronze may also have lead content.
