VA Well Water Test Requirements

Buying a home on a private well with a VA loan? Federal underwriting requires a drinking-water test from a state-certified lab before closing. Here is exactly what the VA program checks for, the rules to watch, and how to get your well tested.

Does my VA loan require a well test?

Yes. If the home you are financing is served by an individual (private) well, the VA program requires a water-quality test before the loan can close. The sample must be analyzed by a laboratory certified by your state to test private-well drinking water, using EPA-approved methods.

Required minimum test panel

  • coliform
  • nitrate
  • nitrite
  • lead

At a minimum, a federally-backed loan test covers coliform, nitrate, nitrite, lead. Your state or lender may require additional analytes depending on local groundwater conditions.

VA well-test rules

A water test is required

When a VA-financed home is served by an individual water supply (a private well), VA requires a water-quality test confirming the water is safe to drink before the loan can close.

Required panel

The test commonly covers coliform, nitrate, nitrite, lead โ€” a coliform-bacteria, nitrate/nitrite, and lead panel. Local VA or lender requirements may add analytes.

Results are valid for 90 days

A VA well water test is generally valid for 90 days. If closing slips beyond that window, the water may need to be re-tested so the lender has a current passing result at closing.

The borrower may not collect the sample

The buyer/borrower cannot collect the water sample themselves. An independent, qualified third party (such as the certified lab or a licensed professional) must collect it so the result is impartial.

A treatment system alone does not satisfy the requirement

Installing a filter or treatment device is not a substitute for a passing test. The water itself must pass the required analysis โ€” a treatment system without a passing lab result does not meet the VA requirement.

Find a state-certified lab

Your VA test must come from a lab certified by your state. We list certification programs by state so you can find an accepted laboratory near you.

State-certified labs

A loan test confirms the water quality of your individual well at the property you are buying. Area risk models โ€” like the county-level USGS estimates elsewhere on this site โ€” describe a region as a whole and do not predict any single well, so they cannot satisfy a lender.

VA well water test FAQ

Does a VA loan require a well water test?

Yes. For a VA-financed home on a private well, VA requires a water-quality test showing the water is safe to drink before closing. The panel commonly covers coliform bacteria, nitrate, nitrite, and lead.

How long is a VA well water test valid?

A VA well water test is generally valid for 90 days. If your closing is delayed past that window, you will likely need a fresh sample so the lender has a current passing result.

Can I collect my own VA well water sample?

No. The borrower may not collect the sample. An independent, qualified third party โ€” such as the state-certified lab or a licensed professional โ€” must collect it so the test result is impartial.

Does installing a water filter satisfy the VA requirement?

No. A treatment system on its own does not satisfy the requirement. The water must pass the required lab analysis; a filter installed without a passing test does not meet the VA standard.
