Very limited

69% of Adams County, MS's surveyed soil comes back "Very limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field.

Adams County, MS is 462.344 square miles with a population of 28,674.

What Adams County's reading doesn't cover

This is a countywide, area-weighted figure across every soil survey map unit in Adams County, MS - never a reading for one specific parcel. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Adams County will actually do.

What a system would cost here

With 69% of Adams 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.
