Q: What was the diameter of the Colonial pipe that carries gasoline through Georgia? Is there some kind of protective coating on that pipe?

—William McKee Jr., Flowery Branch

A: The diameter of the pipe is 36 inches and there is a protective, anti-corrosive coating on the outside of the pipe.

Colonial Pipeline, which is based in Alpharetta, also uses cathodic protection, which is an electrochemical method of preventing corrosion, spokesman Steve Baker told Q&A on the News in an email.

Most of the leakage flowed into a nearby retention pond, according to the U.S. Environmental Protection Agency.

Crews have been cleaning the pond and have constructed underflow dams to prevent the contaminated pond water from draining into Peel Creek, a tributary of the Cahaba River, AL.com reported.
