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.
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.
