About Paper:

As municipal drinking water infrastructure within the United States becomes older, cured-in-place-pipe (CIPP) technology has emerged as an efficient and inexpensive pipe repair method. However, chemical components used and created during the installation process are not well documented and some have been shown to pose a risk to workers and bystanders. A better understanding of these chemicals and their ability to transfer into water is critical. In the present study, epoxy-based drinking water CIPP resin composites were manufactured in an oven and immediately transferred into water to document chemical leaching. This process was repeated four additional times with flushing procedures between stagnations. Water was analyzed for total organic carbon (TOC) concentration and also using gas chromatography (GC) and mass spectrometry (MS). Due to the paucity of data available, results are expected to help inform future post-installation water testing approaches when CIPPs are used for drinking water applications.
