Regional groundwater summary • British Columbia Historical Log Extraction
Bottom Line Up Front
In Merville, the median completed well is 107 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 Unconsolidated (about 36% of local wells).
These municipal aggregates support planning only — they do not replace an accredited laboratory potability test for your own well.

Approximate boundary of Merville
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire Merville.
Most completed wells fall near the median depth of 107 ft. Recorded depths cover 119 wells.
Median depth of 107 ft falls inside the reported range. Deeper completions here usually mean higher mineral content but steadier year-round pressure.
