Well Permits and Regulations: What to Know

There is no single national permit for drilling a well. Here's how the process generally works, and why you need to check the rules where you actually live before you break ground.

There Is No Federal Well Permit

The first thing to understand is that well drilling permits are not a federal matter. The US Environmental Protection Agency (EPA) states plainly that "the quality and safety of drinking water from private domestic wells are not regulated by the Federal Government under the Safe Drinking Water Act nor by most state governments." That statement is about water quality specifically, but the underlying point holds for permitting too: there is no single federal agency that issues well drilling permits or sets one national standard for the process. Instead, EPA directs private well owners to their state water-well contractor licensing agency or local health department for guidance on proper well construction. In practice, permitting authority sits with state and local governments, and which one you deal with depends entirely on where the well is going.

Who Actually Issues the Permit

Because there's no federal system, the agency you apply to varies by location. Depending on your state, a well permit might be issued by a state environmental or water resources agency, a state health department, or a county-level health or environmental health department. A peer-reviewed 2019 study in the journal Water Policy that reviewed private well policy across all 50 states found meaningful fragmentation in how this authority is assigned: 14 states split responsibility for private well regulation across multiple agencies, and Texas alone spreads it across three separate bodies. That fragmentation is part of why there's no shortcut here. You have to identify the specific agency with jurisdiction over your property, and in many states that means starting at the county level rather than the state level.

As one illustration of how decentralized this can get, California's Department of Water Resources describes a system where "regulatory authority over well construction, alteration, and destruction activities rests with local jurisdictions (cities, counties, or water agencies)," with local governments free to adopt their own well ordinances as long as they meet or exceed the state's baseline standards. That's one state's structure, not a national template, but it's a useful example of how much can be delegated downward even within a single state.

What's Typically Required to Get a Permit

While the specifics differ by jurisdiction, a permit application for a new residential well commonly involves some version of the following:

• An application filed before drilling begins. Most jurisdictions expect the permit to be approved before the drilling rig shows up, not after the fact.
• Site information such as the property's location, proposed well location, and its distance from things like septic systems, property lines, or other wells, since many local rules set minimum setback distances to protect against contamination.
• A licensed contractor pulling or co-signing the permit in jurisdictions that require the driller, not just the property owner, to be involved in the application.
• A permit fee, which varies by jurisdiction and is separate from the cost of the well itself.
• A completion report or well log after drilling. Many states require the driller to submit records of the finished well, typically covering depth, casing, and the geological formations encountered, within a set window after the work wraps up.

Because this list is drawn from patterns that show up across multiple jurisdictions, not a checklist for any one place, treat it as a preview of the kinds of questions you'll be asked, not a substitute for reading your own local application.

Why the Rules Vary So Much by State

The Water Policy study found that every state has some form of legal requirement covering the drilling or construction of new wells, so a baseline exists everywhere. But beyond that baseline, the researchers described a "patchwork of regulatory policies and practices across the fifty United States," and the gaps can be significant: only 22% of states had policies addressing what happens to a private well when a home is sold, and just 6% had policies covering private wells on rental properties. Connecticut was the only state the study found with policies touching all nine categories it measured; Maine, at the other end, had minimal coverage. Their geographic analysis also found no statistically significant regional pattern in how strict permit requirements, design standards, inspection authority, or water-quality testing mandates were, meaning you can't assume a state's rules based on its region either.

Contractor licensing tells a similar story. The National Ground Water Association (NGWA) reports that 14 states and two counties incorporate its certification exams into their own well-contractor licensing programs, which means the underlying requirements, and the agencies that administer them, differ from place to place even where a licensing system exists. Typical licensing prerequisites mentioned by NGWA include minimum age and experience standards, passing an exam, submitting an application with fees, and providing references or proof of bonding and insurance, but NGWA is explicit that applicants need to contact their own state's licensing representative for the actual details, since NGWA does not administer state licenses itself.

What This Means for You

Before you schedule a drilling crew, call your county health department or your state's water resources or environmental agency and ask three things: who issues the permit for your property, what information they need from you or your contractor, and what happens after drilling, whether that's an inspection, a completion report, or a water test requirement. A licensed local contractor who regularly pulls permits in your area will usually know this process already; part of what you're paying for when you hire a licensed driller is that they've done this paperwork before and know which office to call. Our well drilling license requirements by state table shows the specific agency and permit authority for your state.

This page is general, national-level information, not legal advice for any specific state. Permit requirements, fees, setback rules, and reporting timelines are set locally and change over time. Always verify current requirements directly with your state water resources or environmental agency, or your county health department, before drilling a well.
