Lethbridge Water Well Depth & Hydrogeology
Regional groundwater summary • GWDrill Historical Log Extraction
Bottom Line Up Front
In Lethbridge the median well is 140 feet deep and draws from Shale / Siltstone bedrock, which supplies 75% of wells here. Water is very hard at about 325 mg/L, so a softener is standard equipment. Rotary drilling is routine and 94% of wells serve ordinary household use. Treatment emphasis: elevated tds, sulfate, potential hydrogen sulfide (h2s). Fine shale layers raise sulfate and sulfide concerns.

Where This Report Applies
Approximate boundary of Lethbridge
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire Lethbridge.
Depth Distribution
Most completed wells fall near the median depth of 140 ft.
Median depth of 140 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.
123 wells Fractured Cretaceous shale formation prominent in western Manitoba. Characterized by high total dissolved solids (TDS) and potential sulfur/iron compounds.
25 wells 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.
16 wells Unclassified hydrogeological formation from legacy provincial drill records.

Present Mineral Risk
- Scale build-up in kettles, heaters and fixtures
- Dissolved iron and manganese staining
- Elevated calcium and magnesium from Shale / Siltstone bedrock
Test before purchasing treatment. Hardness varies well to well within the same quarter section.
Size custom treatment system for this waterDrilling Activity
Historical permit and construction activity by decade.
63% of wells are over 30 years old. Steel casing installed before 1995 can lose integrity, so any older well should get a casing inspection and a bacterial test before you rely on it.
Data-Driven Prescription
The treatment system this water needs
Generated from 325 mg/L hardness, shale / siltstone and a 140 ft median completion depth, for a four-person household. Adjust the assumptions in the builder.
