DNREC Well Viewer Guide
The Well Viewer is DNREC's public map tool for searching well permit and construction records across Delaware.
Short answer: Open the Well Viewer, zoom to your property or search by address, and click on any mapped well point to see available permit details. Treat missing or sparse data as a normal limitation, not a red flag.
Step-by-step
- Open the DNREC Well Viewer in a desktop browser for the clearest map interaction.
- Zoom to your property using an address search or by navigating the map manually.
- Click on any well points shown near your property to open available record details.
- Note the permit number, approximate depth, and construction date if shown.
- Use this information alongside, not instead of, a physical well inspection when making decisions about a property.
Search limitations
The Well Viewer reflects DNREC's available digital records. Older wells, especially those constructed before digital recordkeeping, may be missing or imprecisely located. A record's absence does not mean the well is unpermitted, and a mapped location is approximate, not a survey-grade boundary.
Common mistakes
- Treating the mapped well location as a precise property survey
- Assuming no record means no permit was ever issued
- Using the tool as a substitute for a professional well inspection
When to contact DNREC
Contact DNREC directly if you need an official interpretation of a record, believe a record is inaccurate, or are researching a new well construction or use permit.

Does the Well Viewer show water-quality data?
No. The Well Viewer shows permit and construction records, not water-quality test results. For water quality, you need to test your well through DPH resources or a certified laboratory.
