Lead water service lines in Longueuil

In Longueuil, lead in drinking water comes mostly from lead water service lines, found mainly in buildings built between 1940 and 1950, and up to about 1970. If the private part of your service line is lead, the City asks you to have it replaced and to contact it so it replaces the public portion. Until the full replacement, use a filter pitcher, tap filter or under-sink filter certified to NSF/ANSI 53 for lead reduction; boiling the water does not help.
