There is a long history of lead pipes being used for drinking water distribution, in Canada and around the world. Many homeowners – with the financial fortitude to do so – have replaced them with specialized plastic over the years but lead pipes still remain in many Canadian homes. Lead pipes are susceptible to corrosion due to the ions present in water, which can cause the lead to leach out of the piping and into the water. To try to prevent this leaching, historically some of the lead pipes in Canada were exchanged with copper pipes. However, when the replacement was only partial, the new connection of copper to lead accelerated the problem through galvanic corrosion.
6 west Saint John neighbourhoods to switch to east side water system
Less than two years after switching Saint John's west side to a new drinking water system, the city is now diverting many of those same neighbourhoods to a new water source. The areas affected include Saint John's lower west side, Milford, Randolph, Fundy Heights, Duck Cove and Sand Cove. They are to begin receiving surface water from the Loch Lomond Treatment plant on the city's east side by the end of the year. At the same time the city has cancelled its contract with the engineering firm that was instrumental in the creation of the west side well field water system and hired a law firm to pursue the company, BGC Engineering, for costs.
West Saint John leaks caused by water source changeover, says report
A new $40 thousand report concludes scaly material that built up over decades in the water pipes of west Saint John homes was weakened by a change in the water source, which eventually caused leaks. The report follows over 200 complaints of leaking pipes and a series of angry public meetings that concluded in an ongoing class action lawsuit.
