For many homeowners and property buyers, the discovery of an underground oil tank (UST) can bring a mix of confusion and concern. These tanks were once a common way to heat homes, but as natural gas and other modern heating options became standard, many USTs were left behind. Over time, they can corrode, leak, and create serious environmental and financial risks.
If you’ve discovered an underground oil tank on your property, you’ll likely face a key decision: remove it entirely or abandon it in place. Both options have their advantages and drawbacks, and understanding the differences can help you make the best choice for your property and long-term peace of mind.
What is Underground Oil Tank Removal?
Tank removal means completely excavating the tank, cleaning it of any oil residue, and safely disposing of it. The soil around the tank may also be tested for contamination, and if necessary, remediation will be carried out.
Benefits of Removal:
Permanent Solution – Once the tank is gone, you no longer have to worry about future leaks or issues.
Increases Property Value – Many buyers prefer properties without buried tanks since it reduces liability.
Transparency – There’s no uncertainty about the condition of the tank; it’s simply no longer there.
Easier Insurance Approval – Some insurers won’t cover homes with underground oil tanks, even if abandoned.
Drawbacks of Removal:
Higher Cost Upfront – Excavation and disposal are usually more expensive than abandonment.
More Disruptive – Removal involves digging, which may temporarily impact landscaping, driveways, or walkways.
What is Underground Oil Tank Abandonment?
Tank abandonment involves leaving the tank in place but rendering it harmless. A professional contractor will pump out and clean the tank, fill it with sand, foam, or slurry, and seal it. This prevents collapse and reduces the risk of oil residue leaks.
Benefits of Abandonment:
Lower Cost – Generally less expensive than full removal.
Less Disruption – Since the tank isn’t dug up, your yard and landscaping remain mostly intact.
Quick Process – Often completed faster than removal.
Drawbacks of Abandonment:
Tank Remains in the Ground – Even if filled, the metal tank can still corrode over time.
Resale Challenges – Many buyers are hesitant to purchase properties with abandoned tanks.
Insurance Issues – Some insurance companies may still consider it a liability.
Potential Environmental Risks – If cleaning is not done properly, leftover residue could still contaminate the soil.
Key Factors to Consider
Future Property Plans
If you plan to sell your property in the near future, removal is often the better choice. Buyers and lenders generally prefer clean sites with no underground risks.
Budget
If finances are a concern, abandonment may be a short-term solution. However, keep in mind that removal might be required later during a sale, meaning you could pay more in the long run.
Environmental Safety
Removal ensures you eliminate the risk of soil contamination. Even with abandonment, there’s always the possibility of future leaks if the cleaning process isn’t thorough.
Local Regulations
Some municipalities require removal instead of abandonment, while others may allow both. Always check with local authorities and work with a certified contractor.
Which Option is Right for You?
Choose Removal if:
You want complete peace of mind.
You’re preparing to sell your home.
You want to eliminate future liability and environmental risks.
Choose Abandonment if:
You need a cost-effective, faster solution.
You’re planning to stay in the home long-term and resale isn’t an immediate concern.
Your property layout makes excavation extremely difficult.
Final Thoughts
Deciding between underground oil tank removal and abandonment comes down to weighing cost, convenience, and long-term security. While abandonment may be a suitable temporary fix, removal is generally the more reliable option for protecting your property’s value and ensuring environmental safety.
No matter which route you choose, always hire a certified professional to handle the process. Attempting to deal with a UST on your own can be dangerous, costly, and may not meet local regulations.
