Delaware Well Data · Delaware DNREC
Delaware DNREC well records, searchable by address
Every Delaware well log is filed with the Delaware DNREC non-public well permit records. Those records are public, but they are organized by mapped location and record number — not by street address. We hold 113,332 of them and rebuild the index weekly, so you can start from an address instead.

Enter any Delaware address and we return the wells recorded around it — every Delaware well permit carries a mapped location and the parcel it sits on, but the only address DNREC publishes is the owner's mailing address — which is out of state on one well in eight — so results show the wells around a property 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 113,332 records, so you know what to expect before you search.
| Field | What it tells you | Records with it | Coverage |
|---|---|---|---|
| Original log document | A direct link to the Delaware DNREC copy of the filed log itself. | 113,332 (100%) | |
| Total depth | How deep the hole was drilled, in feet. | 112,429 (99%) | |
| Mapped location | Coordinates, so the log can be found by address instead of by record number. | 111,006 (98%) | |
| Drilling method | Rotary, cable tool, auger, and so on. | 107,154 (95%) | |
| Date completed | When the well was finished and the log filed. | 107,015 (94%) | |
| Tested yield | Gallons per minute the well produced on the driller’s pump test. | 53,886 (48%) | |
| Static water level | How far below the surface the water stood at rest. | 52,425 (46%) |
How this differs from going to Delaware DNREC directly
Nothing here replaces the official record, and for a single well you already have the record number for, Delaware DNREC is the place to go (dnrec.delaware.gov/water/groundwater/well-permitting). 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. Every Delaware well permit carries a mapped location and the parcel it sits on, but the only address DNREC publishes is the owner's mailing address — which is out of state on one well in eight — so results show the wells around a property 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. 113,332 of our records carry a direct link to the Delaware DNREC copy of the filed log itself.

Common questions
With Delaware DNREC — the Delaware DNREC non-public well permit records. Every Delaware driller files a completion report there for each well drilled, and that filing is the authoritative copy of the record. The official site is dnrec.delaware.gov/water/groundwater/well-permitting.
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, every Delaware well permit carries a mapped location and the parcel it sits on, but the only address DNREC publishes is the owner's mailing address — which is out of state on one well in eight — so results show the wells around a property rather than a single wellhead.
No, and it is not meant to be. This is an independent index built from the data Delaware DNREC publishes, rebuilt weekly. Every well we show links back to its own Delaware DNREC 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 113,332 records across 3 counties, with completion dates from 1900 to 2026. That is everything Delaware DNREC publishes in its bulk record set as of 2026-08-22. 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 Delaware DNREC 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.
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.
