Method: medians computed from NC DEQ + USGS records (NC DEQ GW-1 well construction records plus the USGS NWIS inventory, water-supply wells only (monitoring, recovery, injection, remediation and geothermal wells excluded; untyped legacy records kept only with a yield or 50+ ft depth), and USGS rows that duplicate a GW-1 record removed), grouped by ZIP from the recorded address. Cost estimate applies published per-foot ranges to the local median depth — full methodology & sources.
