Jones County, NC's soil, for a septic absorption field

Very limited

93% of Jones County, NC's surveyed soil comes back "Very limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field. Practically, that rules out a simple gravity system for most of the county - 93% of it sits in USDA's most-constrained bucket. Jones County, NC is 471.368 square miles with a population of 9,462.

What Jones County's reading doesn't cover

Two lots a mile apart in Jones County can carry different soil, even though they share one countywide rating. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Jones County will actually do.

What a system would cost here

With 93% of Jones County rating "Very limited", a standard gravity system is not a safe assumption here. The engineered-system range, $10,000-$40,000 (mound or aerobic treatment), is the more realistic number to plan around, against $3,000-$8,000 for a conventional system on the rare lot that passes.
