Bottom Line Up Front
In Simcoe, the median completed well is 83 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 & Gravel (about 61% 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 Simcoe
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire Simcoe.
Most completed wells fall near the median depth of 83 ft. Recorded depths cover 45,068 wells.
Median depth of 83 ft falls inside the reported range. Deeper completions here usually mean higher mineral content but steadier year-round pressure.
Bedrock and drift aquifers recorded by drillers in this area. Recorded for 44,980 of these 45,274 wells.
27,609 of 45,274 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.
6,976 of 45,274 Impermeable glaciolacustrine clay and silt deposits formed in ancient glacial lakes. Acts as an effective regional aquitard confining underlying aquifers.
5,299 of 45,274 Major regional bedrock aquifer formed by Ordovician/Silurian dolomite. Known for reliable, high-volume yields with elevated mineral hardness and dissolved calcium/magnesium carbonates.
3,163 of 45,274 Crystalline Canadian Shield rock. Yields soft, slightly acidic water with minimal dissolved solids, relying on secondary fracture networks for groundwater storage.
1,869 of 45,274 Fractured sedimentary shale formation (including Odanah / Pierre members). Characterized by high total dissolved solids (TDS) and potential sulfur/iron compounds.
59 of 45,274 Deep basal sandstone bedrock unit (including Winnipeg Formation). Supplies exceptionally stable yields; often exhibits moderate mineral hardness with silica-rich water.
5 of 45,274 Unclassified hydrogeological formation from legacy provincial drill records.

Historical permit and construction activity by decade.
66% 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.

Suggested system
Test kit
estimate, confirm with a lab testA test of your own well comes before any equipment. Test for coliform bacteria.
Water testingSediment prefilter
estimate, confirm with a lab testA sediment prefilter is worth considering where wells draw from Sand & Gravel. This follows the aquifer type.
Sediment guideIron and manganese filter
estimate, confirm with a lab testManganese above the aesthetic objective, consider an iron/manganese filter. One monitoring well near this place has median manganese of 0.0574 mg/L. Another has median iron of 0.75 mg/L and median manganese of 0.0634 mg/L. Another has median manganese of 0.0278 mg/L.
Iron and manganese guideWater softener
estimate, confirm with a lab testA softener is likely needed. The nearest monitoring well has a median hardness of 210 mg/L as CaCO₃.
