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. Homes within the suspected lead zone will receive a notice detailing this process and will have one week to opt out of the free water sample collection.

Phone: 519-332-0330, extension 2232

Once you have booked your verification visit, 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.

2019 Results Summary

Year one of the Lead Reduction Program was successful with over 2000 homes sampled and only 2% of these homes exceeding the Ontario drinking water standard of 10 micrograms per liter. The goal for 2020 is to match, or exceed, the number of samples completed last year.
