PA Well Cost by Region
Southeast PA (Chester, Lancaster counties): Limestone and carbonate rock — wells often find water at 100–200 feet at $25–$40/ft. Central PA (Centre, Clearfield): Sandstone and shale — 150–300 feet at $30–$45/ft. Northeast PA (Pocono, Wayne): Crystalline and glacial — 200–450 feet at $35–$60/ft. Southwest PA (Pittsburgh area): Coal measure rocks — wells can be challenging and expensive.
PA DEP Well Regulations
Pennsylvania water wells are regulated by PA DEP under the Water Well Drillers License Act. Drillers must be licensed. A Well Completion Report (Form 3150-FM-WSWM0043) must be filed within 30 days. Minimum 10-foot surface seal required. Pitless adapter required for frost protection.
Water Quality in PA
PA well water varies widely. Northeastern PA has naturally occurring methane in some areas. Southeast limestone areas may have hard water and agricultural nitrates. Coal country in southwestern PA can have iron and manganese issues. Test for coliform, nitrates, pH, hardness, metals, and radon (PA has elevated radon in many areas).
Common Questions
A complete residential well in PA typically runs $8,000–$18,000 installed. Southeast PA limestone areas are less expensive. Northeast and mountain regions with hard crystalline rock run higher.
Depth varies significantly. Lancaster County limestone wells may reach water at 80–150 feet. Pocono Mountain area wells commonly reach 300–450 feet. Always ask local drillers what they see in your specific township.
Yes. Pennsylvania has elevated natural radon in many areas, particularly in the Reading Prong and areas with granite bedrock. Test for radon in both water and air — PA DEP recommends this for all new wells.
