Heard County, GA's soil, for a septic absorption field

Somewhat limited

Soil across 66% of Heard County, GA rates "Somewhat limited" in USDA's septic-absorption-field interpretation.

Heard County, GA is 295.973 square miles with a population of 12,119.

What Heard County's reading doesn't cover

Heard County's rating is an average across the whole county, not a promise about any one lot inside it. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Heard County will actually do.

What a system would cost here

With 66% of Heard County rating "Somewhat 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.

Heard County's rank among Georgia counties
