Method: medians computed from CWI records (water-supply wells only (domestic, irrigation, public/community supply, commercial, industrial) — monitoring, observation, test, injection, heat-pump and environmental boreholes 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.
