Why Early Detection Matters
Underground oil tanks do not announce when they start to fail. Steel tanks corrode from the inside out and the outside in simultaneously, and the first sign of a problem is often a symptom that has been developing for months. Knowing what to look for can mean the difference between a $2,000 tank removal and a $90,000 soil remediation.
The 7 Warning Signs
- Petroleum smell in the basement or yard. Heating oil vapours are heavier than air and migrate into enclosed spaces. A persistent fuel smell is one of the most reliable indicators of a leak or loose fitting.
- Unexplained increase in oil consumption. If your tank empties faster than usual without a change in weather or usage, oil may be escaping through a breach rather than being burned.
- Oily stains or wet spots near the tank. Visible staining on soil, concrete, or the basement floor near the tank area indicates oil has already reached the surface.
- Dead or dying grass in a defined patch. A circular or oval patch of dead grass directly above where the tank is buried is a classic sign of petroleum contamination in the root zone.
- Oil sheen in the sump pump, drainage, or standing water. A rainbow-coloured sheen on water in your sump pit or on standing water near the tank area indicates petroleum has reached the water table or drainage system.
- Rust, bubbling paint, or bulging on visible tank surfaces. If any part of the tank is visible — fill pipes, vent pipes, or exposed sections — rust, bubbling, or deformation indicates advanced corrosion.
- Disconnected or corroded supply lines. The copper or steel lines connecting the tank to the burner corrode over time. Visible corrosion, green staining on copper lines, or disconnected fittings are warning signs.
