USGS NWIS well records, searchable by address

Every North Carolina well log is filed with the USGS National Water Information System groundwater site inventory. Those records are public, but they are organized by mapped location and record number — not by street address. We hold 22,947 of them and rebuild the index weekly, so you can start from an address instead.

Search USGS NWIS records by address

Enter any North Carolina address and we return the wells recorded around it — These are the wells the U.S. Geological Survey has inventoried in North Carolina — a large sample of the state's wells, not every well drilled — so results show the wells around a location rather than a single wellhead.

What a USGS NWIS record contains

Not every filed report carries every field — older records are thinner, and what the state captured changed over the decades. This is the real coverage across all 22,947 records, so you know what to expect before you search.

Total depth How deep the hole was drilled, in feet. 22,947 (100%)
Mapped location Coordinates, so the log can be found by address instead of by record number. 22,947 (100%)

How this differs from going to USGS directly

Nothing here replaces the official record, and for a single well you already have the record number for, USGS is the place to go (waterdata.usgs.gov/nc/nwis/gw). What this site adds is the part that is hard from the source data:

Common questions

Where are North Carolina well logs officially filed?

With USGS NWIS — the USGS National Water Information System groundwater site inventory. Every North Carolina driller files a completion report there for each well drilled, and that filing is the authoritative copy of the record. The official site is waterdata.usgs.gov/nc/nwis/gw.

Can I search USGS NWIS by street address?

Not directly — well records are filed against a mapped location and a record number, not a mailing address, which is the single most common reason people give up on the search. That is exactly the gap this site fills: enter an address on our free lookup and we return the recorded wells around that point, These are the wells the U.S. Geological Survey has inventoried in North Carolina — a large sample of the state's wells, not every well drilled — so results show the wells around a location rather than a single wellhead.

Is this the official USGS NWIS record?

No, and it is not meant to be. This is an independent index built from the data USGS publishes, rebuilt weekly. Every well we show links back to its own USGS NWIS record, so you can always open the original filed log. If our copy and the state's ever disagree, the state's is right.

How many North Carolina well records are there?

Our current copy holds 22,947 records across 100 counties, with completion dates from 1850 to 2022. That is everything USGS NWIS publishes in its bulk record set as of 2026-08-27. Wells drilled before the state's filing requirement — and hand-dug or unpermitted wells — were never filed anywhere, so they are in neither copy.

Does it cost anything?

Searching by address here is free, the same as searching USGS NWIS is free. What we charge for is the compiled property report — every recorded well near one address, with the statistics and the original log links, as one printable document for a sale or a loan file. That is $29.

Every USGS NWIS record near one property, in one document

The property report pulls every recorded well near an address — depths, water levels, yields, drillers , and links to each original filed log — as one printable summary for due diligence.
