100 Mile House Water Well Depth & Hydrogeology

Regional groundwater summary • British Columbia Historical Log Extraction

Bottom Line Up Front

In 100 Mile House, the median completed well is 144 ft deep.

A published hardness range for this place and aquifer is less than 10 to 180, and groundwater can exceed 1,000 mg/L as CaCO₃. That is a regional estimate, not a test of your well. Source: Estimate based on B.C. Ministry of Environment water-quality checks.

Most production draws from Bedrock (about 20% of local wells).

These municipal aggregates support planning only — they do not replace an accredited laboratory potability test for your own well.
