Underground heating oil tanks were common in homes built before natural gas and electric heating became standard, and many are still buried in yards across older neighborhoods – sometimes forgotten entirely by current owners.
Why it matters
An abandoned or leaking underground tank can contaminate soil and groundwater, creating an environmental liability that can complicate a sale, affect financing, or require costly remediation if discovered later.
What to look for
Signs of a buried tank include a capped pipe sticking up from the ground, a fill port near the foundation, or an old furnace room with disconnected oil lines. A tank sweep (using ground-penetrating equipment) can confirm whether one is present on a property.
If a tank is found
Options typically include professional removal, or proper closure and abandonment in place by a licensed contractor, along with soil testing to confirm there’s no contamination. Addressing it before listing avoids surprises during a buyer’s inspection.
