The author of this article responds to another article in the same issue of the Journal American Water Works Association ("Water Contamination Caused by Gasoline Permeating a Polybutylene Pipe") by stating that, although plastic pipes are vulnerable to permeation by organic solvents, the incidence of this actually happening is low. He stresses the importance of stricter requirements for liquid storage tanks and increased public awareness of the dangers associated with the improper disposal of organic solvents to reduce the likelihood of permeation.
