Private wells in Lac qui Parle County
In 2015 about 3,066 of Lac qui Parle County’s 6,856 residents (45%) got their drinking water from a private well, by the USGS estimate. That is the 26th highest share of the 87 Minnesota counties in the USGS table, and the 74th highest number of private-well users.

Soils and septic systems here
USDA soil surveys rate 87% of Lac qui Parle County’s rated land “very limited” for a conventional septic drain field, 13% “somewhat limited” and 0% “not limited”, the 77th highest “very limited” share of 85 Minnesota counties with survey data. The most common limits: slow percolation (dense or clay soil) on 93%; a high water table (saturated soil near the surface) on 84%; fast seepage below the field (risk to groundwater) on 14%.
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.
