Method: medians computed from ODNR records (water-supply wells only (domestic, public/municipal, commercial, industrial, agricultural/irrigation, fire protection) — monitoring, test/boring, heat-pump, injection, abandoned/sealed and unclassified wells excluded; depths 0–5,000 ft). Cost estimate applies published per-foot ranges (checked 2026-06-11) to the local median depth — full methodology & sources.
