Method: medians computed from USGS NWIS records (USGS NWIS groundwater inventory, water-supply wells only (monitoring wells, test holes and injection wells excluded), and only wells carrying a measured depth). Cost estimate applies published per-foot ranges (checked 2026-06-11) to the local median depth — full methodology & sources.
