VILLAGE OF DUNNOTTAR Water Well Depth & Hydrogeology
Regional groundwater summary • GWDrill Historical Log Extraction
Bottom Line Up Front
In VILLAGE OF DUNNOTTAR the median well is 87 feet deep and draws from Carbonate Rock (Limestone/Dolomite) bedrock, which supplies 79.7% of wells here. Water is very hard at about 352 mg/L, so a softener is standard equipment. Rotary drilling is routine and 99.7% of wells serve ordinary household use. Treatment emphasis: scale buildup, calcium/magnesium hardness. Carbonate chemistry creates persistent calcite scaling.

Where This Report Applies
Approximate boundary of VILLAGE OF DUNNOTTAR
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire VILLAGE OF DUNNOTTAR.
Depth Distribution
Most completed wells fall near the median depth of 87 ft.
Median depth of 87 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.
345 wells Major regional bedrock aquifer formed by Ordovician/Silurian dolomite. Known for reliable, high-volume yields with elevated mineral hardness and dissolved calcium/magnesium carbonates.
87 wells Unclassified hydrogeological formation from legacy provincial drill records.
1 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.

Present Mineral Risk
- Scale build-up in kettles, heaters and fixtures
- Dissolved iron and manganese staining
- Elevated calcium and magnesium from Carbonate Rock (Limestone/Dolomite) 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.
32% 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 352 mg/L hardness, carbonate rock (limestone/dolomite) and a 87 ft median completion depth, for a four-person household. Adjust the assumptions in the builder.
