Tallahatchie County, MS's soil, for a septic absorption field

Very limited

Soil across 91.4% of Tallahatchie County, MS rates "Very limited" in USDA's septic-absorption-field interpretation. This is the reading that pushes a project toward an engineered system rather than a conventional one, and it covers 91.4% of Tallahatchie County's land.

What Tallahatchie County's reading doesn't cover

USDA's survey covers the whole of Tallahatchie County, MS at once, not any single address. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Tallahatchie County will actually do.

What a system would cost here

With 91.4% of Tallahatchie 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.
