Mississippi Well Data · MDEQ + USGS
MDEQ + USGS well records, searchable by address
Every Mississippi well log is filed with MDEQ's Office of Land and Water Resources statewide well database together with the USGS National Water Information System groundwater inventory. Those records are public, but they are organized by mapped location and record number — not by street address. We hold 192,965 of them and rebuild the index weekly, so you can start from an address instead.

Enter any Mississippi address and we return the wells recorded around it — These are the wells the U.S. Geological Survey has inventoried in Mississippi — 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.

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 192,965 records, so you know what to expect before you search.
| Field | What it tells you | Records with it | Coverage |
|---|---|---|---|
| Mapped location | Coordinates, so the log can be found by address instead of by record number. | 192,965 (100%) | |
| Total depth | How deep the hole was drilled, in feet. | 166,512 (86%) | |
| Driller | The licensed company that drilled the well and signed the log. | 96,331 (50%) | |
| Original log document | A direct link to the MDEQ + USGS copy of the filed log itself. | 73,052 (38%) | |
| Date completed | When the well was finished and the log filed. | 69,996 (36%) |
How this differs from going to MDEQ/USGS directly
Nothing here replaces the official record, and for a single well you already have the record number for, MDEQ/USGS is the place to go (waterdata.usgs.gov/ms/nwis/gw). What this site adds is the part that is hard from the source data:
- An address is enough. You do not need a record number, a section-township-range, or a latitude to start. These are the wells the U.S. Geological Survey has inventoried in Mississippi — 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.
- The neighbours, not just the well. Buyers and lenders care what depth and yield are normal nearby, which means reading many records at once, not one.
- The same statistics everywhere. Median depth, static water level and yield are computed identically in every county, so two counties can actually be compared. The exact filters are on the methodology page.
- The original is always one click away. 73,052 of our records carry a direct link to the MDEQ + USGS copy of the filed log itself.

Common questions
With MDEQ + USGS — MDEQ's Office of Land and Water Resources statewide well database together with the USGS National Water Information System groundwater inventory. Every Mississippi 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/ms/nwis/gw.
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 Mississippi — 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.
No, and it is not meant to be. This is an independent index built from the data MDEQ/USGS publishes, rebuilt weekly. Every well we show links back to its own MDEQ + USGS record, so you can always open the original filed log. If our copy and the state's ever disagree, the state's is right.
Our current copy holds 192,965 records across 82 counties, with completion dates from 1870 to 2019. That is everything MDEQ + USGS publishes in its bulk record set as of 2026-10-12. Wells drilled before the state's filing requirement — and hand-dug or unpermitted wells — were never filed anywhere, so they are in neither copy.
Searching by address here is free, the same as searching MDEQ + USGS 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 $49.
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.
