Very limited
Soil across 96.9% of McCreary County, KY rates "Very limited" in USDA's septic-absorption-field interpretation.

What McCreary County's reading doesn't cover
McCreary 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 McCreary County will actually do.
What a system would cost here
With 96.9% of McCreary 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.
