Private wells in Stearns County
In 2015 about 50,248 of Stearns County’s 154,708 residents (32%) got their drinking water from a private well, by the USGS estimate. That is the 50th highest share of the 87 Minnesota counties in the USGS table, and the 4th highest number of private-well users.

Soils and septic systems here
USDA soil surveys rate 96% of Stearns County’s rated land “very limited” for a conventional septic drain field, 4% “somewhat limited” and 0% “not limited”, the 45th highest “very limited” share of 85 Minnesota counties with survey data. The most common limits: slow percolation (dense or clay soil) on 63%; a high water table (saturated soil near the surface) on 60%; fast seepage below the field (risk to groundwater) on 46%.
Where soils are limited, inspections more often find drain fields that sit in seasonally wet soil, and replacement systems are often mounds or other engineered designs. A county-wide rating, not a test of one lot: a site evaluation decides.
