What the ground in Farmington is like

The USDA soil survey rates mapped ground in Farmington for septic drain-field suitability across roughly 34 square miles. About 67% 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 Farmington, 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 56% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement56.2%
• Slope43.3%
• Depth to bedrock18.1%
• Filtering capacity16.1%

This is survey data for mapped areas, not a substitute for a site evaluation on your own lot. Conditions on a single parcel can differ from the map.
