Wells in Saint-Jean-sur-Richelieu
Saint-Jean-sur-Richelieu has private-well owners; the City has publicly reminded them to have their water tested, ideally twice a year.
How testing works in Quebec
There's no free provincial service: send samples to a lab accredited by Quebec's environment ministry (the CEAEQ list), which supplies the bottles. The ministry recommends testing for bacteria at least twice a year, in spring and fall, plus a chemical analysis while the well is in use.
What to test for
- Bacteria (total coliforms and E. coli): at least once a year, and after flooding, heavy rain or work on the well.
- Nitrate, especially near farmland or septic systems.
- Metals and naturally occurring contaminants such as arsenic, uranium or manganese when a well is new and every few years after, depending on local geology.
