Abstract
Polymeric pipes are increasingly being installed in water distribution systems because of their many advantages. Contaminant migration from polymer pipes into drinking water is a growing concern in the United States and environmental engineers are evaluating the role of these materials on water quality, system operation, and regulatory compliance. To aid these efforts and serve as a source of background information, the authors critically review available literature on polymeric potable water pipes in use, known contaminants released from in-service and new piping, and their perceived sources, and outline future challenges in the United States and abroad.
