Method: medians computed from ISGS records (ISGS water wells; engineering, mineral and stratigraphic test borings, mine shafts, outcrops and monitoring wells are excluded, as are wells the survey records as plugged; depths 0-5,000 ft). Cost estimate applies published per-foot ranges (checked 2026-06-11) to the local median depth — full methodology & sources.
