What the ground in Farmington is like

The USDA soil survey rates every mapped parcel for its suitability as a septic drain field. Across Farmington's 34.5 square miles, 66.5% of the rated ground is classed "Very limited", meaning restrictions severe enough that a conventional field is often unsuitable and an engineered system may be required.

The limiting features the survey records most often here:

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

The most common soil series underfoot: Haplargids, Avalon, Farb.

This is survey data for the area, not a substitute for a site evaluation on your own lot. A soil scientist or your county health department tests the actual parcel, and the result can differ from the map.
