Cobble Hill Water Well Depth & Hydrogeology
Regional groundwater summary • GWDrill Historical Log Extraction
Bottom Line Up Front
In Cobble Hill the median well is 168 feet deep and draws from Sand & Gravel Drift bedrock, which supplies 572.4% 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: sediment turbidity, localized iron/manganese. Unconsolidated sediments demand particulate intrusion monitoring.

Where This Report Applies
Approximate boundary of Cobble Hill
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire Cobble Hill.
Depth Distribution
Most completed wells fall near the median depth of 168 ft.
Median depth of 168 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.
830 wells Unclassified hydrogeological formation from legacy provincial drill records.
Water Quality Profile

Present Mineral Risk
- Scale build-up in kettles, heaters and fixtures
- Dissolved iron and manganese staining
- Elevated calcium and magnesium from Sand & Gravel Drift 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.
66% 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, sand & gravel drift and a 168 ft median completion depth, for a four-person household. Adjust the assumptions in the builder.

Water Testing
Tap Score Canadian Essential Water Test
Nothing gets sized without numbers. Regional modelling puts hardness near 325 mg/L in sand & gravel drift, but your own well can sit well off that median.

Sediment Prefilter
SpringWell Whole-House Spin-Down Sediment Filter
Sand & Gravel Drift aquifers carry fine sand and turbidity that destroys softener resin and UV lamp clarity.

Whole-Home Softening
SpringWell SS1 48,000 Grain Whole-Home Softener
At 325 mg/L (very hard) a 4-person household loads roughly 5.7k grains of hardness per day onto the plumbing.
