Method: medians computed from TDLR SDR records (water-supply wells only (domestic, irrigation, stock, public supply, industrial) — monitoring, environmental borings, test holes, injection and geothermal 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.
