Private wells are the owner’s responsibility: federal public drinking-water rules do not apply to them. Good decisions start before the rig arrives.

Hire a licensed driller

Most states license water well contractors and require permits or well logs. Check the driller’s license with your state agency and ask about recent wells drilled near you. Browse well drilling companies by state.

Permits and setbacks

States and counties set minimum distances between wells and septic systems, property lines and other hazards. Your local health or environmental department can tell you the rules before you pick a site.

Questions to ask

  • How is the price structured (per foot drilled, casing, grouting, pump and pressure system)?
  • Who handles the permit and the well log filed with the state?
  • How will the well be disinfected and tested after completion?
  • What happens if the first hole is dry?

Test the water every year

EPA and CDC recommend testing private well water at least once a year for total coliform bacteria, nitrates, total dissolved solids and pH, and testing again after flooding, repairs or changes in taste, odor or color. Use a state-certified lab; your local health department can help.

Common questions

How often should I test well water?

EPA and CDC recommend at least once a year for total coliform bacteria, nitrates, total dissolved solids and pH, plus extra tests if problems or local risks arise.

Who regulates private wells?

Construction is typically regulated by states and local health departments. Federal public drinking-water rules do not cover private household wells.
