How to Know If Your Tank Needs Removal
Underground oil tanks can deteriorate over time without visible signs. If your tank’s age is unkown or it’s out of warranty, it’s likely at risk of leaking, which can lead to soil and groundwater contamination, hefty cleanup costs, and property devaluation. Here are some common red flags:
- Sudden drops in oil levels without increased usage
- Oil odors in your yard or basement
- Wet spots or discoloration in the surrounding soil or vegetation
- Poor tank maintenance records
- Home inspection reports or insurance policy requirements
- Tank is out-of-warranty
