Bottom Line Up Front
In RM of Thompson, the median completed well is 42 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.
Most production draws from SAND AND GRAVEL (about 54% of local wells).
These municipal aggregates support planning only — they do not replace an accredited laboratory potability test for your own well.

Median depth of 42 ft falls inside the reported range. Deeper completions here usually mean higher mineral content but steadier year-round pressure.
Aquifer Composition
Bedrock and drift aquifers recorded by drillers in this area.
Sand & Gravel Aquifer Glacial Drift Aquifer
53.6% 148 of 276 Shallow to intermediate glacial drift aquifer deposited in alluvial channels or outwash plains. Yields softer water but requires continuous sediment filtration and shallow bacterial monitoring.
Undifferentiated Aquifer Regional Formation
19.2% 53 of 276 Unclassified hydrogeological formation from legacy provincial drill records.
Sedimentary Shale Formation Fractured Shale Aquifer
18.1% 50 of 276 Fractured sedimentary shale formation (including Odanah / Pierre members). Characterized by high total dissolved solids (TDS) and potential sulfur/iron compounds.
Glacial Drift Silt & Till Protective Overburden
7.6% 21 of 276 Dense, low-permeability clay-rich glacial deposits with localized silt lenses. Serves as a natural confining barrier protecting deeper aquifers from surface contamination.
Sandstone Bedrock Formation Basal Bedrock Aquifer
1.1% 3 of 276 Deep basal sandstone bedrock unit (including Winnipeg Formation). Supplies exceptionally stable yields; often exhibits moderate mineral hardness with silica-rich water.
Carbonate Bedrock (Limestone / Dolomite) Primary Bedrock Aquifer
0.4% 1 of 276 Major regional bedrock aquifer formed by Ordovician/Silurian dolomite. Known for reliable, high-volume yields with elevated mineral hardness and dissolved calcium/magnesium carbonates.

76% of dated wells are over 30 years old (pre-1995). Steel casing installed before 1995 can lose integrity over time. Any older well should get a casing inspection and a certified bacterial test before reliance.
