Bottom Line Up Front
In RM of Rockwood, the median completed well is 118 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 LIMESTONE OR DOLOMITE (about 88% 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 RM of Rockwood
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire RM of Rockwood.
Most completed wells fall near the median depth of 118 ft. Recorded depths cover 2,557 wells.
Median depth of 118 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.
2,412 of 2,741 Major regional bedrock aquifer formed by Ordovician/Silurian dolomite. Known for reliable, high-volume yields with elevated mineral hardness and dissolved calcium/magnesium carbonates.
275 of 2,741 Unclassified hydrogeological formation from legacy provincial drill records.
30 of 2,741 Fractured sedimentary shale formation (including Odanah / Pierre members). Characterized by high total dissolved solids (TDS) and potential sulfur/iron compounds.
17 of 2,741 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.
3 of 2,741 Dense, low-permeability clay-rich glacial deposits with localized silt lenses. Serves as a natural confining barrier protecting deeper aquifers from surface contamination.
2 of 2,741 Crystalline Canadian Shield rock. Yields soft, slightly acidic water with minimal dissolved solids, relying on secondary fracture networks for groundwater storage.
2 of 2,741 Deep basal sandstone bedrock unit (including Winnipeg Formation). Supplies exceptionally stable yields; often exhibits moderate mineral hardness with silica-rich water.

Historical permit and construction activity by decade.
67% 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 testAn iron filter is worth considering because wells in this place draw from LIMESTONE OR DOLOMITE. This follows the aquifer type. Iron and manganese were not used from a monitoring-well test.

Hard-water guideBecause water wells in RM of Rockwood average 118 ft into limestone or dolomite, contractors equipped with heavy rotary rigs and proper casing seals are recommended. Contact local drillers directly or request competitive bids.
