Septic & well water services in St. Louis County, MN

Minnesota's largest county spans thin till over Precambrian bedrock, from Duluth Complex gabbro along Lake Superior to the Biwabik iron formation of the Mesabi Range and bog lowlands to the north. Bedrock within a few feet of grade, red clay soils on the Duluth slope, and extensive peat leave conventional trenches viable on only a fraction of rural sites, so mounds dominate. Bedrock wells at 100 to 400 feet yield soft, iron-stained water at low rates.
