Bottom Line Up Front
In Saint-Denis, the median completed well is 169 ft deep.
A published hardness range for this place and aquifer is under 60 to above 180 mg/L as CaCO₃. That is a regional estimate, not a test of your well. Source: Estimate based on Health Canada hardness bands.
These municipal aggregates support planning only — they do not replace an accredited laboratory potability test for your own well.

What this is not
- Not a laboratory result for a well on your property.
- Not a reason to size a softener. Size equipment from a lab test.
- Not a drilling quote. A cost line on this page is a national estimate, not a price for one well.
Health Canada has not set a maximum acceptable concentration for hardness. A wide published range can sit in more than one USGS band.
