Lead concentration in the drinking water

The drinking water produced and distributed by Montreal’s water supply system is of excellent quality and meets all the regulatory standards pertaining to maximum permitted lead content as set by the Government of Quebec. However, when water stagnates in a lead service for a prolonged period of time, lead dissolution may occur thereby increasing the concentration of lead at the tap.

Please note that until 2001 the maximum concentration of lead in drinking water as per Quebec norms was 50 micrograms per liter after 5 minutes of flow. This regulation existed for several decades. In an effort to reduce the exposure of the population to lead, the government of Quebec reduced the maximum concentration of lead in the water to 10 micrograms per liter after 5 minutes of flow.

Over the past 8 years, the City of Westmount has been actively replacing lead services through our capital works program as well as our annual water maintenance program. To date, an estimated 30 to 40% of lead water services in Westmount have been replaced with copper services.

Should you have any questions about the sampling results at your home, please contact the Public Works department at 514-989-5468.

Beginning January 1, 2006, the City of Westmount became responsible for the distribution of drinking water to all residences and businesses in its territory. This meant changes to how problems should be reported and how the public would be notified of service interruptions or urgent situations. It is important to know where to call to report a problem or to get an answer to a question about drinking water.

No. Westmount’s water system was DEFINITELY NOT privatized. In fact, City Council and Westmount Public Works remain wholly responsible for the system, and work diligently to ensure a high level of service to the community. It is a responsibility that the City Council and administration take VERY seriously.

The source and the quality of the water remains the same, but residents must contact the City of Westmount directly if they have questions and concerns.

Until December 31, 2005, the City of Montreal had been responsible for the treatment and distribution of drinking water, including the repair and maintenance of water mains. In 2006, Westmount took over the management of the local distribution network for the first time.

Because of this new responsibility, Westmount sought out specialized services to help ensure that the municipality would meet the needs of citizens. A private firm was engaged to carry out both regular maintenance of the system and emergency repairs, including major water main breaks and smaller leaks.
