Water test for a new wellNot required statewide

Pennsylvania has no statewide private well construction standards or mandatory testing. DCNR licenses drillers but states that licensure does not require demonstrated knowledge of proper drilling. Some counties and townships (for example Chester County) have local well ordinances.

Water test when a home is soldNot required statewide

No statewide requirement. FHA, VA and USDA loans typically require a water test; some townships require testing at transfer.

What the state recommends

DEP recommends testing every year for total coliform bacteria, nitrate, total dissolved solids and pH, plus additional tests for any suspected contaminant. Penn State Extension recommends a broader panel every 3 years (metals, hardness, chloride, sulfate) and testing after flooding, repairs or a change in taste, odor or color.

Free or low-cost testingAvailable

DEP regional offices sell low-cost bacteria test kits. Penn State Agricultural Analytical Services Lab offers mail-in drinking water kits at cost.
