Water supply
The 2 municipal drinking water distribution systems in Gatineau serve 152,208 people out of a population of about 306,105. Water source: surface water (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 Outaouais region, homes tested by Health Canada had a median concentration of 47 Bq/m³, and 12.7% exceeded the Canadian guideline of 200 Bq/m³, out of 63 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.
