Method: medians computed from OWRB records (OWRB reported well logs, water wells only (water-quality, monitoring, site-assessment and heat-exchange holes excluded); depths 0-5,000 ft. Water-level figures are OWRB's reported depth to first water). Cost estimate applies published per-foot ranges (checked 2026-06-11) to the local median depth — full methodology & sources.
