What the ground in Mandan is like
The USDA soil survey rates mapped ground in Mandan for septic drain-field suitability across roughly 14 square miles. About 90% of the rated ground is classed "Very limited", meaning the soil has one or more features unfavorable for a conventional drain field, and the limits generally cannot be overcome without major soil reclamation, special design or expensive installation.
In Mandan, the leading limit is slow water movement: effluent does not drain through the soil fast enough, so a conventional field can back up or pond when the ground cannot keep pace. The survey flags that limit on about 63% of the rated ground here.
