The Environmental Protection Agency has joined the hunt for the source of toxic contamination that has forced the shutdowns of two New Castle area public water supplies.
Efforts are now targeting the area around New Castle Airport.
The Wilmington News Journal reports that state officials say aircraft fire-fighting foams that were used for training at the Delaware Air National Guard complex could be the source of the pollution.
But, so far, they added, the connection with the pollution is still unconfirmed.
An EPA team has said that Artesian Water and New Castle’s Municipal Service Commission wells are probably the sources of the contamination.
