Soils and septic systems here
USDA soil surveys rate 97% of Leavenworth County’s rated land “very limited” for a conventional septic drain field, 3% “somewhat limited” and 0% “not limited”, the 37th highest “very limited” share of 105 Kansas counties with survey data. The most common limits: slow percolation (dense or clay soil) on 91%; a high water table (saturated soil near the surface) on 53%; steep slopes on 33%.
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.
