Water supply
The 3 municipal drinking water distribution systems in Montréal serve 1,912,518 people out of a population of about 1,915,366. Water source: surface water (Fleuve Saint-Laurent, river).
Source: directory of municipal drinking water distribution systems, Quebec Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs. The directory describes where the water comes from and the size of each system; it contains no test results and does not say which addresses are connected.
Radon
In the Montréal region, homes tested by Health Canada had a median concentration of 26 Bq/m³, and 6.8% exceeded the Canadian guideline of 200 Bq/m³, out of 74 measurements.
This figure describes a region, not this property. Radon is a natural gas that comes from the ground, but its concentration in a home depends on cracks in the foundation, the drainage and the ventilation: two neighbouring houses can differ by a factor of ten. Only a long-term test on site gives the actual concentration. Test kits cost a few dozen dollars and must stay in place for at least three months during the heating season.
