What Happens to the Gasoline Left in Junked Cars at US Salvage Yards?

Millions of cars are scrapped in the United States every year, each carrying gasoline and other fluids. Salvage yards are required to drain fuel before processing vehicles further — the petrol is siphoned out, then filtered and either resold or disposed of according to hazardous waste regulations. The process is designed to prevent soil and groundwater contamination.
