Bisphenol A in relining of water pipes (2011)

Relining is a process of recoating the entire inside of the water pipe instead of replacing the old pipes with new ones. The concept of relining rather than replacing drinking water pipes was developed in the late 1980s. The recoating of
the drinking water pipes is often done with an epoxy resin containing Bisphenol A (BPA) or Bisphenol A Diglycidyl Ether (BADGE), which can leach BPA.
