I've learned so much about gas stations just by watching this one video. I now know what I'm talking about at work tomorrow...
"A typical gasoline station has a storage capacity of 30,000 to 40,000 gallons in underground tanks. In the past, these tanks were sometimes subject to spills from overfilling and to leaks caused by corrosion. Today, station owners have taken several important steps to reduce these risks."
