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.
