Method: medians computed from PaGWIS records (PaGWIS water wells; wells recorded solely as monitoring, observation, geothermal, injection or oil-and-gas holes are excluded, as are the few records the state labels a tunnel, drain, sinkhole or pond; depths 0-5,000 ft). Cost estimate applies published per-foot ranges (checked 2026-06-11) to the local median depth — full methodology & sources.
