Lead Sampling Program


Municipalities in Canada are required to complete lead testing after Health Canada’s recent decision to lower the Maximum Acceptable Concentration (MAC) of lead in water from 0.010 mg/L to 0.005 mg/L.

Cochrane is testing the water from 60 homes in different neighbourhoods throughout the community, focusing on those built prior to 1975. Random testing is scheduled between May and September 2021.

Please note: if your home is randomly selected for water testing, Town staff will be in touch to arrange. We have COVID-19 safety protocols in place to maintain the health, safety and well-being of residents and staff.  

Water supplied to local homes and businesses is lead-free and meets or exceeds all provincial and federal health guidelines. 

Cochrane’s water distribution system was built in the 1950s and 60s, when the most common material used was copper. Before that, most existing homes were on private wells; connections to the Town’s water infrastructure was made using copper pipes. Over the years, as the Town has inspected and replaced pipes, no lead pipes have been found.  

This does not mean all homes are free of lead: until 1986, copper pipes were soldered with material containing 50% lead and 50% tin. Solder joints are mainly inside homes; service connections from the water main to the property line are Town-owned and are compression fit (so, no solder joints). Lead solder may have been used inside the property line and individual homes, and some faucets pre-2010 could contain lead from the manufacturing process.
