Drinking water analysis

To ensure the health of your family

Drinking water analysis


Drinking water from artesian wells must be tested annually. This requirement has been put in place to ensure that the water that flows from your tap is of good quality and in compliance with the Règlement sur la qualité de l’eau potable (Regulation respecting the quality of drinking water) issued by the Ministère de l’Environnement et Lutte contre les changements climatiques.

Drinking water can contain pathogenic microorganisms that are very harmful to your health, such as: E. coli, fecal coliforms/enterococci, nitrates/nitrites, arsenic, etc. Water may be contaminated despite a clear or limpid appearance, and no particularly bad odor or taste. Water quality can only be confirmed by a drinking water analysis carried out by an approved laboratory.

Drinking water quality Testing schedule:

  • 1 to 2 times per year, in spring or fall, to detect the presence of microbiological particles, if any.
  • At least once, usually when purchasing a new property to detect the presence of chemical substances in the soil, which is generally correlated with the water quality.
  • When modifications are made directly to the well or to the ground around it;
  • If you notice any sudden change in the taste, smell or appearance of your drinking water.

Drinking water analysis includes:

  • An easy-to-use sampling kit;
  • Analysis of your samples by a certified laboratory;
  • Interpretation of analysis results.
