Pennsylvania Groundwater Information System (PaGWIS)
Pennsylvania Geological Survey
Public PaGWIS points include well location, use, depth, reported yield and data-reliability fields; public-water supplies are excluded.
What you can find in Pennsylvania well records
Available fields vary by individual filing, but the live Pennsylvania integration can surface:
- well depth
- reported yield
- well use
- water use
- municipality
- depth to bedrock
- location method
- data reliability
How to use the record before buying a property
Pennsylvania's public layer exposes both practical well metrics and reliability fields that help users avoid over-reading a single mapped point.
Start with the address search, compare the closest records and their distances, then open the official source before treating a record as the subject property's well. If water quality or current performance matters, use current testing and an on-site well inspection.
Pennsylvania coverage limitation
PaGWIS point locations and data quality vary by record, and the mapped public layer is not a complete inventory of every water-supply well.
Official Pennsylvania source
WellLookup is independent of Pennsylvania Geological Survey. The underlying public source is Pennsylvania Groundwater Information System (PaGWIS). WellLookup adds address search, nearby-record comparison and property-focused reporting; it does not change the official record.
Frequently asked questions
Yes. Enter a street address and WellLookup will search nearby mapped records from the supported Pennsylvania source.
Not necessarily. Location precision varies, so verify identifiers, documents and the physical well before relying on the match.
The $29.99 USD property report organizes the available evidence, nearby comparisons, source limitations and follow-up questions into one PDF.
