Data sources

The report is only as good as the source underneath it.

Check My Well identifies the public source used for each supported jurisdiction and treats missing or ambiguous data as uncertainty—not certainty.

Why fields differ

Each jurisdiction has its own record format, terminology and history. A field that looks similar across two datasets may not have identical units or meaning. Check My Well normalizes only fields that can be mapped responsibly.

Updates

Production imports should retain source identifiers and refresh on a schedule appropriate to each public dataset. Material source changes should trigger a data-adapter review before the new records are published.

Check the property first

Run the free address lookup, then request local help from the property report if you need a contractor.

Check My Well summarizes public records and general information for informational and due-diligence purposes. Nearby records do not guarantee a property’s well depth, yield, water quality, condition or future drilling result. Verify material decisions against original records, current laboratory testing and qualified local professionals.
