Method: medians computed from WI DNR records (drilled water wells (well-construction reports) — geothermal loop/heat-exchange, anode, test and dry holes 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.
