Don’t Take Chances with Your Well Water: Test It Twice a Year
Artesian Well
For artesian well water testing in Drummondville, Saint-Hyacinthe, or nearby areas, trust EAUVY M-N. With over 35 years of expertise in bacteriological and mineralogical analysis of potable water, we ensure your water is safe to drink.
Even if your artesian well water appears clear, odorless, and tasteless, it may still contain bacteria, viruses, protozoa, nitrates, and nitrites that can be harmful to health. Contamination events can occur and can only be detected through bacteriological and mineralogical analysis.
Most disease-causing viruses, bacteria, or protozoa in water come from human or animal waste. Since it is technically impossible to test for all pathogens, microbiological indicators such as E. coli, enterococci, and total coliform bacteria are used to detect contamination.
When to Test Artesian Well Water
Water from surface or tubular wells (commonly called "artesian wells") must comply with the Regulation Respecting the Quality of Drinking Water (Q-2, r.40), whether serving individual households or networks of up to 20 people.
For water intended for human consumption, a microbiological analysis must be conducted at least twice a year (in spring and fall) by an accredited laboratory. This analysis includes testing for E. coli, enterococci, and total coliform bacteria. The presence of these bacteria indicates the potential for viruses, bacteria, or protozoa that can cause illness.
Additionally, the government requires at least one physico-chemical analysis during a well’s use. This test measures arsenic, manganese, barium, chlorides, sodium, iron, sulfates, fluorides, and the total hardness of the water (calcium and magnesium levels). It also detects nitrate-nitrite levels, often originating from agricultural fertilizers, manure, sanitary waste, or decomposing animals.
Extra tests should be performed if your water’s taste, odor, or appearance changes or if modifications are made to the well or its surrounding soil.
