Method: medians computed from IDWR records (IDWR well records, excluding the 8,758 monitoring, injection, test, dewatering, cathodic-protection and heat-exchange wells that are not water supplies; depths 0-5,000 ft). Cost estimate applies published per-foot ranges (checked 2026-06-11) to the local median depth — full methodology & sources.
