What Miller County's reading doesn't cover

Nothing about Miller County, AR'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 Miller County will actually do.

What a system would cost here
