Bottom Line Up Front

In RM of Alonsa, the median completed well is 100 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 57% of local wells).

These municipal aggregates support planning only — they do not replace an accredited laboratory potability test for your own well.

Where This Report Applies

Approximate boundary of RM of Alonsa

Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire RM of Alonsa.

Depth Distribution

Most completed wells fall near the median depth of 100 ft. Recorded depths cover 901 wells.

Median depth of 100 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.

Carbonate Bedrock (Limestone / Dolomite) Primary Bedrock Aquifer
56.5%

511 of 905 Major regional bedrock aquifer formed by Ordovician/Silurian dolomite. Known for reliable, high-volume yields with elevated mineral hardness and dissolved calcium/magnesium carbonates.

Sand & Gravel Aquifer Glacial Drift Aquifer
33.5%

303 of 905 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.

Undifferentiated Aquifer Regional Formation
3.4%

31 of 905 Unclassified hydrogeological formation from legacy provincial drill records.

Sandstone Bedrock Formation Basal Bedrock Aquifer
3.3%

30 of 905 Deep basal sandstone bedrock unit (including Winnipeg Formation). Supplies exceptionally stable yields; often exhibits moderate mineral hardness with silica-rich water.

Sedimentary Shale Formation Fractured Shale Aquifer
1.9%

17 of 905 Fractured sedimentary shale formation (including Odanah / Pierre members). Characterized by high total dissolved solids (TDS) and potential sulfur/iron compounds.

Glacial Drift Silt & Till Protective Overburden
1.4%

13 of 905 Dense, low-permeability clay-rich glacial deposits with localized silt lenses. Serves as a natural confining barrier protecting deeper aquifers from surface contamination.

  • Not a reason to size a softener. Size equipment from a lab test.

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.

Test kit

estimate, confirm with a lab test

A test of your own well comes before any equipment. Test for coliform bacteria.

Water testing
2

Iron and manganese filter

estimate, confirm with a lab test

An 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.

3

Water softener

estimate, confirm with a lab test

Some wells nearby test above 120 mg/L, a softener may help, confirm with a lab test. 11 wells test above 180 mg/L.
