When buying a home in New Jersey, especially one that was built before the 1980s, it’s crucial to be aware of any hidden underground oil tanks. For decades, oil tanks were used to store heating oil in many homes across the state. However, with the transition to natural gas and other heating sources, many of these tanks were abandoned and left underground, posing significant risks to the property and the environment.

While a professional oil tank sweep using tools like metal detectors or Ground Penetrating Radar (GPR) can detect anomalies underground, sometimes these tools only provide an initial clue. This is where an exploratory dig becomes essential.

What is an Exploratory Dig?

An exploratory dig is a controlled excavation that follows the findings of an oil tank sweep. It is designed to confirm the presence of a hidden oil tank by carefully digging into a specific area where a potential tank may be located. This process is done to ensure that the initial scan findings are accurate and to verify what’s actually underground before making any further decisions.

Why Is an Exploratory Dig Necessary?

1. Accurate Confirmation of Findings

Sometimes, metal detectors or GPR scans pick up signals from metal or anomalies in the ground that might not always be an oil tank. These could be due to other buried materials, pipes, or debris. An exploratory dig allows professionals to visually confirm whether the detected anomaly is indeed an oil tank, providing peace of mind to homeowners or prospective buyers.

2. Environmental Protection

Old, leaking oil tanks pose a significant threat to the environment. Oil leaks can contaminate the soil and even reach the groundwater, affecting local ecosystems and posing health risks. When a tank is confirmed during an exploratory dig, homeowners can take the necessary steps to remove the tank and clean up any contamination before it causes further damage. Addressing the issue early can help protect not only the property but the surrounding environment.

3. Preventing Costly Remediation Later

The costs associated with soil remediation after a leaking oil tank can be substantial—sometimes reaching $50,000 or more. By conducting an exploratory dig, you can prevent the need for costly remediation efforts. If a tank is located and verified, it can be removed promptly, minimizing the chances of an expensive cleanup down the road.

4. Legal and Financial Responsibility

In New Jersey, property owners are legally responsible for any contamination caused by oil tank leaks. Even if the tank was abandoned by previous owners, the current owner is still held liable for any damage it causes. An exploratory dig ensures that potential liabilities are uncovered, so homeowners can address them before they become legal or financial burdens.

5. Facilitate Property Transactions

For those buying or selling homes in New Jersey, an exploratory dig helps streamline real estate transactions. A hidden oil tank can delay a property sale or lower the property’s value. Buyers may demand tank removal or remediation before closing, which can create unwanted delays. By identifying and removing any potential underground tanks before the sale, both buyers and sellers can proceed with confidence and peace of mind.

How Does an Exploratory Dig Work?

Step 1: Initial Assessment

Before an exploratory dig begins, the property will undergo an oil tank sweep. This can involve metal detectors or GPR technology, which identify anomalies in the ground that may indicate the presence of an underground tank.

Step 2: Targeted Excavation

Once an anomaly is detected, the team will perform an exploratory dig to expose the suspected area. This targeted excavation is small and focused, ensuring minimal disturbance to the property. The goal is to uncover only the area where the potential oil tank is located, ensuring that the process is efficient and cost-effective.

Step 3: Confirmation

Once the area is dug up, the team will examine the findings. If a tank is discovered, it is documented and photographed for reference. At this point, the next steps can be determined, whether it involves tank removal, remediation, or sealing the tank if it is still in acceptable condition.

Step 4: Documentation and Next Steps

After the exploratory dig, a detailed report will be provided. This report will include photographs, the exact location of the tank, and recommendations for the next steps—whether that be removal, remediation, or legal action to ensure the tank is properly decommissioned.
