VA Water Test Requirements for Well Water

What VA requires for well water

VA water test requirements for a well start from one fact: VA does not set its own water standard. Its lender's handbook, VA Pamphlet 26-7, covers wells in Chapter 12 (minimum property requirements) under the topic "Individual Water Supply". It says the water from an individual water supply, such as a private well, must meet the requirements of the health authority having jurisdiction. If the local authority does not have specific requirements, the guidelines set by the Environmental Protection Agency (EPA) apply.

That puts the real decisions with your local health authority, usually a county or city health department, and with your lender, which applies them to your loan. Requirements are set by your local health authority (or EPA standards where none exist); confirm with your lender.

Requirements also vary by location. VA's handbook says information about minimum property requirements for properties in specific locations is listed by state on VA's Local Requirements page (linked in the sources below). When we checked it on 2026-11-07, its state entries covered wood-destroying insects, not water. For water, the local health authority's rules are what vary, so ask your lender which authority's rules apply.

The same topic covers a few more points that affect a purchase:

• Who takes the sample. All testing must be done by a disinterested third party (see the next section).
• How long a result lasts. A result stays valid for a limited time after it is certified (see below).
• Signed statements. Some kinds of water supply, and any filtration system, need a written acknowledgement from the Veteran.
• Distances. The appraiser must be familiar with the minimum distances required between private wells and sources of pollution, but is not required to sketch or note the distances between the well, property lines, septic tanks, drain fields or buildings.
• Public water. If public water is available and the local authority requires the home to connect to it, the connection is required.

For more information, the handbook points to EPA's directory of state private well programs and to CDC's guidance on testing well water. Both are linked in the sources at the end of this page.

FHA vs VA in one line: VA's handbook accepts springs, lakes, rivers, sand-point wells and artesian wells once the appraiser comments and the Veteran acknowledges them in writing, while HUD's handbook makes a home served by them ineligible for FHA insurance. Our page on FHA water test requirements covers HUD's rules, and our guide to moving to a house with well water covers the purchase as a whole.

Who can collect and test the sample

This is the rule that trips up most buyers and sellers. VA's handbook says all testing must be performed by a disinterested third party, and that includes collecting the water sample at the source and transporting it to the lab.

The handbook names who may collect and test the sample:

• the local health authority;
• a commercial testing laboratory;
• a licensed sanitary engineer; or
• another party that is acceptable to the local health authority.

It also says who may not: at no time will the Veteran or another interested party collect or transport the sample. In plain terms, that rules out you as the buyer, and it is reasonable to read it as ruling out anyone else with a stake in the sale. If you are not sure whether a person counts as disinterested, ask your lender before the sample is taken, not after.

Arrange the collection early. Some health departments collect samples themselves; in Ohio, for example, the Department of Health tells well owners to contact their local health district to learn what water samples it can collect. Whoever does it, ask them to record who collected the sample and when, because that record is part of what your lender will look at.

How long the result stays valid

VA's handbook says water quality test results are valid for 90 days^[1] from the date certified by the local health authority, unless the local authority indicates otherwise.

Two details matter here. First, the clock starts on the date the local health authority certifies the result, which is not always the day the sample was taken. Second, your local authority can set a different period, so ask what applies where the home is. If your closing date moves, check whether the result will still be inside its window on the new date. A result that expires before closing means a new sample, collected the same way.

When the Veteran must sign a statement

For some kinds of water supply, VA does not refuse the property, but it does require the buyer to know what they are getting. The handbook says the appraiser must comment in the appraisal, and the Veteran must acknowledge awareness in writing, when the water to the property is:

• supplied by dug wells, cisterns, or holding tanks used with water that is bought and hauled to the site;
• provided with a mechanical chlorinator;
• provided through springs, lakes, rivers, sand-point wells or artesian wells; or
• supplied by a rainwater catchment system.

Filtration systems. If the property has a water filtration system, the Veteran must acknowledge in writing that the water must be continuously treated as the local health authority requires, and that for the system to work it must be inspected and maintained, including replacing filters as the manufacturer recommends. Before you sign, ask the seller for the system's manual and service records so you know what upkeep you are taking on.

What to test for

VA does not publish an analyte list. The tests that count for your loan are the ones your local health authority requires, or EPA's guidelines where it has none, as your lender applies them. Ask your lender for the list in writing.

To find your local authority, start with EPA's directory of private well programs by state, the same page VA's handbook links to. EPA notes that while most states have zero or limited regulations for private drinking water wells, states do have programs to assist well owners. CDC adds that you should contact your health department to find out what other germs or chemicals to test for based on where you live, and that you should use a state-certified laboratory.

Here is what three state agencies say:

• Michigan. The Department of Environment, Great Lakes, and Energy (EGLE) tells well owners that protecting their drinking water quality is their responsibility. It lists coliform bacteria, nitrate, nitrite and a range of metals, including arsenic and uranium, among the standard concerns for private wells, and offers tests through its laboratory.
• Pennsylvania. The Department of Environmental Protection (DEP) says it does not regulate private wells. Its private wells pages cover water testing and how to find a certified drinking water lab.
• Ohio. The Department of Health recommends that private water system owners test total coliform bacteria, E. coli, nitrates and arsenic on a regular basis. That is Ohio's recommendation for owners, not a VA rule.

Commonly requested; confirm locally: total coliform bacteria and nitrate, which are part of the yearly baseline CDC recommends for every well (total coliform bacteria, nitrates, total dissolved solids and pH). Our bacteria water test guide and nitrate water test guide explain each test.

Planning the timeline

The validity window and the lab's turnaround set your schedule. Work back from your closing date:

1. Get the requirements first. Ask your lender which tests it needs, in what form, and whether the local health authority must certify the result. Then confirm the list with the local health authority.
2. Book the collector. Line up a disinterested third party to collect the sample and take it to the lab. Call as soon as you have a contract.
3. Plan around the bacteria sample. A bacteria sample has to reach the lab within a short holding window, and some labs receive samples only on certain days. Our bacteria water test guide explains the window and how to plan for it.
4. Ask about turnaround. Ask the lab how long results take, and ask the local health authority how long its certification takes if one is needed.
5. Check the window. Make sure the certified result will still be valid on your closing date, with room for a short delay.

If the water does not pass

A result that misses the local requirement does not end the purchase on its own, but it does need an answer before closing. Talk to your lender and the seller about who will fix the problem and how much time that will take.

• Find the cause first. The result tells you what to look for. Ask the lab or your local health authority what the result means for the well before you buy anything.
• Decide on treatment only from a certified result. Choose any treatment based on the certified lab result, not a home kit or a guess. If the result meets the requirement, no treatment is needed.
• Retest the same way. After the fix, a disinterested third party collects a new sample. The new certified result is what shows the problem is solved, and it starts a new validity window.
• Remember the acknowledgement. If the fix adds a filtration system, the Veteran's written acknowledgement about continuous treatment and filter replacement applies.

If a result raises a health question for someone in the home, talk to a health professional.
