Hardin County, OH Septic Rating

Hardin County's SSURGO septic rating

Very limited

USDA puts Hardin County, OH at "Very limited" for septic absorption fields, the dominant reading across 99.4% of the county's soil. That reading means a conventional system is a poor bet here - it's already USDA's strictest "very limited" bucket, not a partial constraint. The county spans 470 square miles, home to 30,402 people.

What this number does and doesn't tell you

Two lots a mile apart in Hardin County can carry different soil, even though they share one countywide rating. Budget $750-$1,850 for a real perc test on any specific parcel - that's the only figure a permit application accepts.

Hardin County: conventional vs. engineered cost

99.4% of Hardin County carrying a "Very limited" reading changes the realistic budget here. Conventional systems run $3,000-$8,000 where they pass; where they don't, engineered alternatives (mound or aerobic treatment, whichever the health department requires) run $10,000-$40,000 - budget toward the higher figure until a perc test says otherwise.
