Goshen County, WY's soil, for a septic absorption field

Very limited

49.2% of Goshen County, WY's surveyed soil comes back "Very limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field. A standard gravity system routinely fails on ground like this; the same share of the county falls in USDA's worst absorption-field bucket outright. Goshen County, WY is 2,225.613 square miles with a population of 12,635.

What Goshen County's reading doesn't cover

Nothing about Goshen County, WY's SSURGO figure applies to a specific address - it's a county-wide average. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Goshen County will actually do.

What a system would cost here

With 49.2% of Goshen 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.
