In Halton Region, drinking water comes from either Lake Ontario or groundwater wells. The water is treated and then delivered to homes and businesses through a system of underground water service lines.

Homes built in 1952 might have lead service connections or internal plumbing. Homes built before 1990 might have brass fittings containing lead, or lead solder connecting to the copper pipes.
Exposure to lead has decreased significantly due to its reduction or removal from construction materials, gasoline, paint and solder, as well as changes to the Building Code. Today, most exposure to lead is from food, dirt and dust.
Halton Region is committed to providing residents and businesses with safe, clean drinking water. Halton Region’s Lead Sampling Program ensures that all drinking water is lead-free through:
The MOECC Drinking Water Quality Standard for lead is 10 micrograms/litre. This level was set to protect the most "at risk" population, pregnant women and small children. Historical test data indicates that the potential for lead in private plumbing in Halton Region drinking water is low. Since 2012, MOECC has provided an exemption for Halton Region for regular sampling of residential/private properties. Halton Region continues to conduct regular sampling of public infrastructure for the presence of lead.
Although the risk of lead in Halton Region's drinking water remains low, the MOECC has requested that Ontario municipalities, including Halton Region, do a series of private/residential lead sampling in 2017.
