South Carolina Well Data · Well logs
South Carolina well logs
Every time a well is drilled in South Carolina, the driller files a completion report — the well log — with the SC Department of Environmental Services' Coastal Plain Well Inventory together with the USGS National Water Information System groundwater inventory. We hold 22,764 of them and rebuild this index weekly, so you can find one by address instead of by record number.

Well logs are filed by location, not by house number. Enter any South Carolina address and we'll pull the recorded wells around it — These are the wells the U.S. Geological Survey has inventoried in South 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.

Not every filed report carries every field — older logs are thinner, and what the state captured changed over the decades. This is the actual coverage across all 22,764 records, so you know what to expect before you look anything up.
| 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. | 22,764 (100%) | |
| Total depth | How deep the hole was drilled, in feet. | 22,271 (98%) | |
| Date completed | When the well was finished and the log filed. | 17,224 (76%) | |
| Driller | The licensed company that drilled the well and signed the log. | 10,844 (48%) | |
| Static water level | How far below the surface the water stood at rest. | 8,925 (39%) | |
| Original log document | A direct link to the SCDES + USGS copy of the filed log itself. | 8,540 (38%) | |
| Tested yield | Gallons per minute the well produced on the driller’s pump test. | 8,377 (37%) | |
| Street address | A street address on the filed report (varies a lot by state and era). | 8,052 (35%) |
When South Carolina's wells were drilled
Dated logs by decade of completion (17,221 of 22,764 records carry a usable completion date). The shape of this chart is mostly the history of the filing requirement, not of drilling — thin early decades mean the logs weren't kept, not that nobody drilled.
| Decade | Logs filed | |
|---|---|---|
| 1860s | 1 | |
| 1870s | 2 | |
| 1880s | 5 | |
| 1890s | 11 | |
| 1900s | 1,799 | |

Three ways to find a well log here
- By address — the free lookup maps an address to the wells recorded around it. This is what most people want: "how deep is the well on the place I'm buying."
- By county — each county page carries the median depth, water level and yield computed from every log filed there, plus the drillers working it.
- By driller — every log names the company that drilled the well, so the 79 South Carolina drillers in our directory each have a profile built from their own filed logs.

Where these records come from
All of it is public record from the SC Department of Environmental Services' Coastal Plain Well Inventory, together with the groundwater wells the U.S. Geological Survey has inventoried in South Carolina (gis.des.sc.gov/coastalplainwell). We don't hold anything the state doesn't publish. More on that database and what a filed record carries: SCDES + USGS well records. What we add is that the records are indexed by location, the statistics are computed the same way in every county, and the whole thing is refreshed weekly. Our filters and the exact computation are on the methodology page (statistics use USGS NWIS groundwater inventory, water-supply wells only (monitoring wells, test holes and injection wells excluded), and only wells carrying a measured depth).
Common questions
Yes. South Carolina drillers are required to file a completion report for each well, and those reports are kept by the SC Department of Environmental Services' Coastal Plain Well Inventory together with the USGS National Water Information System groundwater inventory. Anyone can look them up. This site is an independent index of that public record — we re-read the source and recompute every page weekly.
Well logs are filed by location, not by street address, so you search the map rather than a house number. Enter the address on our free lookup and you'll see the recorded wells around that spot — These are the wells the U.S. Geological Survey has inventoried in South 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. Each one shows its depth, static water level, tested yield, and a link to the original filed log.
The oldest dated log in our copy was completed in 1860; the newest is from 2026. Coverage thins out the further back you go — older wells were often never filed, and filing requirements tightened over time.
Most likely it was never filed. Wells drilled before the state's reporting requirement — and hand-dug or unpermitted wells — have no log at all. It also happens that a log exists but its recorded location is off, in which case it will show up under a neighboring property. Neither is something we can fix from the source data, and we'd rather say so than invent a record.
The useful parts for a buyer or a homeowner: how deep the well is, how high the water stands in it, how many gallons per minute it produced when tested, what the driller hit on the way down, and who drilled it. Together those say whether the well is likely to keep producing and what a replacement would cost.
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.
