Bottom Line Up Front
In Nipissing, the median completed well is 188 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 Crystalline Bedrock (about 87% 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 Nipissing
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire Nipissing.
Most completed wells fall near the median depth of 188 ft. Recorded depths cover 9,661 wells.
Median depth of 188 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 9,632 of these 9,679 wells.
8,381 of 9,679 Crystalline Canadian Shield rock. Yields soft, slightly acidic water with minimal dissolved solids, relying on secondary fracture networks for groundwater storage.
617 of 9,679 Major regional bedrock aquifer formed by Ordovician/Silurian dolomite. Known for reliable, high-volume yields with elevated mineral hardness and dissolved calcium/magnesium carbonates.
564 of 9,679 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.
51 of 9,679 Impermeable glaciolacustrine clay and silt deposits formed in ancient glacial lakes. Acts as an effective regional aquitard confining underlying aquifers.
11 of 9,679 Fractured sedimentary shale formation (including Odanah / Pierre members). Characterized by high total dissolved solids (TDS) and potential sulfur/iron compounds.
7 of 9,679 Deep basal sandstone bedrock unit (including Winnipeg Formation). Supplies exceptionally stable yields; often exhibits moderate mineral hardness with silica-rich water.
1 of 9,679 Unclassified hydrogeological formation from legacy provincial drill records.

Historical permit and construction activity by decade.
55% 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 testingIron 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 iron of 18.1 mg/L and median manganese of 3.76 mg/L. Another has median manganese of 0.0208 mg/L. Another has median manganese of 0.0418 mg/L.
