Why Illinois drilling runs above the US average
Well drilling pricing in Illinois reflects three regional factors: geological difficulty (rocky Northeast and Mountain West charge premium per-foot rates), licensed driller density, and permit / water-test requirements. The 1.05× factor is calibrated from state geological survey data and 2025 HomeAdvisor cost reports.
