Regional groundwater summary • British Columbia Historical Log Extraction
Bottom Line Up Front
In Mudge Island, the median completed well is 180 ft deep.
A published hardness range for this place and aquifer is less than 10 to 180, and groundwater can exceed 1,000 mg/L as CaCO₃. That is a regional estimate, not a test of your well. Source: Estimate based on B.C. Ministry of Environment water-quality checks.
Most production draws from Bedrock (about 20% 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 Mudge Island
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire Mudge Island.
Most completed wells fall near the median depth of 180 ft.
Median depth of 180 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 16 of these 82 wells.
16 of 82 Major regional bedrock aquifer formed by Ordovician/Silurian dolomite. Known for reliable, high-volume yields with elevated mineral hardness and dissolved calcium/magnesium carbonates.

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 0.566 mg/L and median manganese of 0.261 mg/L. Another has median manganese of 0.1725 mg/L.
Iron and manganese guideBecause water wells in Mudge Island average 180 ft into bedrock, contractors equipped with heavy rotary rigs and proper casing seals are recommended. Contact local drillers directly or request competitive bids.
