What the ground in Beaufort is like

The USDA soil survey rates mapped ground in Beaufort for septic drain-field suitability across roughly 25 square miles. About 99% 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 Beaufort, the leading limit is seepage in the bottom layer: water moves through the soil too quickly. That is the opposite of a slow-drainage problem. The risk is untreated effluent reaching groundwater before the soil can clean it, not backup at the surface. The survey flags that limit on about 84% of the rated ground here.

The limiting features the survey records most often here:

• Seepage, bottom layer84.3%
• Depth to saturated zone72.8%
• Slow water movement43.1%
• Filtering capacity41.6%

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.
