What Montgomery County, NY's soil rates for a septic system

Very limited

86.6% of Montgomery County, NY'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. Montgomery County, NY is 403.111 square miles with a population of 49,648.

What Montgomery County's reading doesn't cover

This is a countywide, area-weighted figure across every soil survey map unit in Montgomery County, NY - 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 Montgomery County will actually do.

What a system would cost here

With 86.6% of Montgomery 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.
