Before you rely on this for one lot
This is a countywide, area-weighted figure across every soil survey map unit in Scotland County, NC - never a reading for one specific parcel. The real answer for one lot is still a site-specific perc test, running about $750-$1,850 (typically near $1,300).
Budgeting for a system in Scotland County, NC
