How Deep Are Wells in Franklin County, PA?
The median residential well in Franklin County is 178 ft deep, based on 6,420 completion reports filed with the Pennsylvania Department of Conservation and Natural Resources. Most fall between 82 and 420 ft; the deepest on record is 1100 ft.
That is 5 ft deeper than the Pennsylvania state-wide average of 173 ft (an n-weighted average across every Pennsylvania county with reported data). Depth depends on local geology, your own site could sit well outside Franklin County's typical range.
Source and method: Pennsylvania Department of Conservation and Natural Resources Pennsylvania Groundwater Information System (PaGWIS), via PASDA, extracted 2026-07-14. Figures include only wells recorded as residential (domestic) use, with a reported depth between 15 and 2,000 ft (to exclude likely data-entry errors). PaGWIS carries no completion date, so figures cover all domestic wells on record rather than only recent ones, and the records are compiled from driller-submitted and historical sources at varying reliability that DCNR does not independently verify. These are figures self-reported by licensed drillers to the state; treat this as a planning reference, not a guarantee for any specific property.
