Find Your Well Log Instantly

You don’t need the driller’s name to find your well log. Use our location-based search tool above or contact your state’s water-well authority with your property address. State agencies file well logs by location, so they can locate any records associated with your property even without knowing the drilling company. Most states organize records by parcel number, coordinates, or street address.

In many cases, yes. If a well log was filed when drilled, the state or county likely still has it (even if only on paper or microfilm). However, wells older than 40-50 years might predate mandatory logging. If your well is very old and no log exists, consider having a licensed well contractor document the well’s depth and construction now to create a record for future use.

Absolutely. Many states require providing the well log to buyers during real estate transactions. Even where not mandated, having the well record available expedites sales and gives buyers confidence. It proves proper construction and provides details on water depth and yield. Always have your well log - and recent water quality test results - ready when selling.

In most U.S. states, well logs are public information that anyone can access via state websites or requests. A few states restrict access, requiring owner permission, but generally well logs aren’t confidential. DrillerDB aggregates publicly available well records nationwide, making it easy to search without navigating multiple government offices.

Don’t panic. Some wells (especially older ones) aren’t in online systems. Contact your state’s water resources department, geological survey, or county health department directly. Provide your address and any details you have. They can often look up records in their archives. As a last resort, a qualified well contractor can inspect your well to document key details.

A well log typically includes: drilling date, total depth, static water level, yield (gallons per minute), casing material and depth, screen details, grouting information, geological formations encountered, pump specifications, water quality test results at drilling, and the driller’s license information. This data is crucial for maintenance, repairs, and understanding your water source.

Start with the records search above - most states file a well log by property address, so a match is strong evidence a well exists. Confirm it on the ground by looking for the casing and cap, a well pit lid, or the pressure tank and its water line inside the house. A prior survey, a septic permit, or the seller’s disclosure will usually note a private well too.

Trace the main water line back from the pressure tank to the wall it exits, then walk that line across the yard - the wellhead is often in line with that run. Look for a capped steel or PVC pipe standing about a foot above grade. A plat map or the survey drawn for closing often marks the well location directly.

Older wellheads sometimes get buried under landscaping or fill. A metal detector responds to a steel casing, and a thin probe rod will find the casing a few inches down. A casing is supposed to terminate above grade, so if you find one buried, plan to have it brought up to code or properly decommissioned by a licensed contractor.

Many counties keep well logs at the county health department or environmental office, and most states also aggregate them at the state water-resources department or geological survey. The search tool at the top of this page checks 18 million+ of these records by address in one place, which is usually faster than contacting each office.
