What the ground in Rock Hill is like

The USDA soil survey rates every mapped parcel for its suitability as a septic drain field. Across Rock Hill's 44.9 square miles, 84.0% 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 movement99.7%
• Depth to saturated zone21.3%
• Depth to bedrock20.2%
• Seepage, bottom layer8.4%

The most common soil series underfoot: Urban land, Cecil, Brewback.

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.
