How often to test
We have not found a Virginia recommendation yet. EPA's advice applies: test every year for coliform bacteria, nitrate, total dissolved solids and pH.
Free testing
We found no statewide free testing program in Virginia. Ask your county health department whether it runs one.
Testing programs and help
- The Virginia Household Water Quality Program (Virginia Tech and Virginia Cooperative Extension) runs drinking-water testing clinics; it held 90 in 2024. Participants pay a fee. [1]

Radon in indoor air, not in water. EPA: Zone 1 = highest potential (average indoor radon may be above 4 pCi/L); Zone 2 = 2 to 4; Zone 3 = below 2. EPA says the map should not be used to decide whether an individual home needs testing.

Loan test (FHA, VA, USDA) in Virginia
- VA. Test results are valid for 90 days from the date the local health authority certifies them, unless the local authority says otherwise. VA’s chapter names no list of contaminants: the water must meet the local health authority’s requirements, or EPA guidelines where it has none. Your lender may ask for specific tests.
- FHA. A well test is required in the situations FHA’s handbook lists, among others, and the report may not be more than 180 days old at disbursement.
- USDA. Guaranteed loans need a water quality test for a private well, done by the local health authority or a state-certified lab, and no more than 180 days old at closing.
Lenders can ask for more (extra tests, a particular lab, who takes the sample): ask your lender before you book. Federal rules as read on Nov 3, 2026 source 1 source 2 source 3.
