About 3,964 households in Potter County, 58% of the county, rely on a private well. Nobody tests that water unless the owner does.
Most homes in Potter County are on a private well: about 3,964 households, 58% of the county. That makes Potter County one of the places in Pennsylvania where the water department is the homeowner.
Pennsylvania sets no statewide construction or testing standard for private wells, so what applies in Potter County depends on the county and the township. Some municipalities require a permit or a test at sale; many require nothing. Check with the township before drilling or selling, and treat the state guidance below as the floor.
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.
No statewide requirement. FHA, VA and USDA loans typically require a water test; some townships require testing at transfer.
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.
DEP regional offices sell low-cost bacteria test kits. Penn State Agricultural Analytical Services Lab offers mail-in drinking water kits at cost.
No state-certified lab sits within 40 miles of the center of Potter County. That is common in rural Pennsylvania, and the practical answer is a mail-in kit: the lab ships bottles, you sample at the kitchen tap and ship them back cold. The finder below widens the search to the whole state.
