Virginia Well Water
Last reviewed October 29, 2026
Overview
Private wells supply water to many Virginia households. Because they are generally not regulated like public systems under the federal Safe Drinking Water Act, testing and wellhead protection are the owner’s responsibility.
Hydrogeology & what it means
Virginia uses Valley-and-Ridge carbonate, Piedmont crystalline, and Coastal Plain aquifers. The documented regional concerns below indicate what is worth testing for — not what any individual well contains.
Documented regional concerns
- Hard water from carbonate (limestone/dolomite) aquifers.
- Radon in water where granitic or uranium-bearing bedrock is present.
- Iron and manganese causing staining and metallic taste (aesthetic).
- Naturally acidic (low pH) water that can corrode plumbing and leach metals such as lead or copper.
- Naturally occurring fluoride above recommended levels in some groundwater.
These are documented possibilities, not a reading of your well
Frequently asked questions
What should well owners in Virginia test for?
A practical panel for Virginia private wells includes Total coliform bacteria, Nitrate (as N), pH, Total hardness, Radon, Iron, Manganese, Lead, Copper, Fluoride. Test bacteria and nitrate at least annually and use a state-certified laboratory; confirm local recommendations with your state health department and Virginia Tech Cooperative Extension.
Are private wells regulated in Virginia?
Private wells are generally not covered by the federal Safe Drinking Water Act, though Virginia or local rules may apply to construction, permitting, or testing. Public-system limits such as EPA MCLs are useful reference points, not automatic legal limits for your well.
