Sarnia Lead Reduction Program

The City of Sarnia’s drinking water is transported through the municipal watermain below the street, which then connects to smaller underground pipes that bring the drinking water into your home (also known as water service lines).

In certain parts of the city, these water service lines are made of lead which poses a threat to the vulnerable public (i.e. small children, pregnant women, women who are planning to become pregnant, as well as the elderly). Excessive exposure to lead can lead to health effects.

The City of Sarnia is conducting lead verification visits to homeowners who live in the Suspected Lead Zone to visually inspect in-home water services and to take a water sample from your tap. There is no cost for this visit. In response to the COVID-19 pandemic, all water samples will be collected from an outside tap and no in-home water service shall be performed. Homes within the suspected lead zone will receive a notice detailing this process and results will be sent after a free water sample collection.

Are you in the Suspected Lead Zone?

The map below indicates potential lead service areas in Sarnia.

The suspected lead zone is classified into the Primary Suspected Lead Zone and Secondary Suspected Lead Zone. The “Primary Zone” is bounded by Murphy Road and the St. Clair River (east to west) and Highway 402 to St. Andrew St (north to south). The Secondary Zone includes properties by Lakeshore Road, Exmouth St and London Line as shown on the map.

If your home is in the Lead Zone depicted on the map, call our office Monday through Friday 8:00 am – 4:00 pm to book your free verification visit!

Phone: 519-332-0330, extension 2232

Once you receive a notice requesting a sample for your property, a qualified City of Sarnia team will arrive at your home to collect the water sample from an outside tap. It is requested that all obstacles are removed before staff arrive. Since samples are collected at the outside tap it is not required for a homeowner/tenant to be home at the time of sampling.

NOTE: Even though the visible plumbing in your home doesn’t look like lead, the service lines underground may still be made of lead.

2020 Results Summary

In 2020, the Lead Reduction Program was able to gain information on more than 93% of properties in the suspected lead zone through water sampling, historical data analysis and maintenance notes. It was also determined that less than 2% of these homes exceeded the Ontario Drinking Water Quality Standard of 10 micrograms per liter. The goal for 2021 is to collect samples from the remaining properties and develop plans to eliminate all lead lines from the water system.
