What the ground in Summerville is like

The USDA soil survey rates every mapped parcel for its suitability as a septic drain field. Across Summerville's 22.6 square miles, 89.2% 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:

• Depth to saturated zone100.0%
• Slow water movement91.8%
• Seepage, bottom layer35.7%
• Flooding22.2%

The most common soil series underfoot: Mouzon, Bonneau, Ocilla.

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.
