Location: Bryn Mawr, PA
Summary: During a heating oil delivery, an overfilled heating oil tank burst in the basement of a vacationing family, resulting in a spill of over 300 gallons of oil. A substantial amount of oil was collected in the French drain and sump, and discharged to the storm sewer, which flowed to a nearby stream. The French drain also allowed oil to accumulate and spread beneath the entire basement floor slab. Heating oil also seeped into the basement walls, and fumes were spread throughout the house by the forced-air heating system.
