Risks Associated with Residential Heating Oil Tanks

Heating oil was once the primary home heating fuel on Vancouver Island before the advent of natural gas in 1992. Prior to this transition, homes typically relied on forced-air furnaces or oil-fired boilers. To store oil, tanks were usually placed on the property, often buried underground because of their unsightly appearance. These underground heating oil tanks (USTs) were equipped with a vent pipe to prevent pressure build-up and a fill pipe for refilling when empty. 

Concerns regarding the environmental impacts of these underground tanks have led many homeowners to seek professional assistance. Waypoint Environmental Services Ltd specializes in safely assessing and removing these older tanks. By the 1960s-1970s, above-ground tanks became more common; however, many older homes still have underground tanks that were installed before this shift.

Environmental Impact of Old Heating Oil Tanks

It’s estimated that by 2011, about 150,000 homes in the Capital Regional District (CRD) used heating oil systems. Many of these homes had underground heating oil tanks that may not have been properly documented. While some municipal fire departments and the CRD maintain records of tank installations, they are not always comprehensive. These records can help identify properties with tanks, but they cannot guarantee the complete removal of contamination.

It’s a common misconception that removing an old heating oil tank automatically cleans up any contamination that may have occurred. Even if a tank has been removed, past leaks can still result in contamination. This is why it’s essential to conduct proper environmental assessments to ensure the property is safe and free from hazardous materials.

The Role of Environmental Consultants in Victoria, BC

When it comes to ensuring the safety of a property with an old heating oil tank, environmental consultants are indispensable. They provide expertise in assessing potential contamination and offering recommendations for the next steps. Environmental consulting firms can conduct thorough site inspections and take soil and water samples to determine the extent of any contamination.

If contamination is found, remediation work will be necessary. This work may involve cleaning up the soil or treating the groundwater. Depending on the level of contamination, remediation costs can vary. However, most properties can be cleaned up for under $25,000. In some cases, particularly if the contamination has reached the water table, costs can exceed this amount. These remediation efforts are crucial to maintaining property value and ensuring the safety of future occupants.

Oil Tank Removal: What You Need to Know

If you suspect that your property may have an old, unused heating oil tank, it is essential to take action. The process begins with an inspection, which may include visual checks, historical record searches, and, in some cases, ground-penetrating radar (GPR) scans to confirm the tank’s presence. If a tank is found, fuel tank removal contractors should be called to safely remove the tank and assess for any leaks.

Once the tank is removed, the soil should be tested to check for contamination. If the soil is clean, an environmental consultant can prepare a report confirming that no contamination was found. This report can be used by potential buyers, lenders, and insurance companies as proof of the property’s condition. However, if contamination is found, remediation steps will be required, and further soil and groundwater analysis may be necessary.

Costs and Benefits of Tank Removal

Tank removal can often be completed for less than $25,000, but more severe cases, especially those involving groundwater contamination, can cost more. For properties with contamination concerns, proper due diligence during the buying or selling process is crucial to prevent future liabilities. Homebuyers should work closely with environmental consultants to assess potential risks, while sellers should consider preemptively addressing tank removal and potential contamination issues before listing their property.
