Cure-In-Place Pipe (CIPP) technologies have been developed to solve many challenges associated with the renewal of degraded water and sewer pipelines. As the technologies have evolved, different construction materials and curing approaches have been developed, for functional reasons but also to address potential releases and exposures to potentially toxic chemicals associated with the process.

The overall objective of this research is to develop a critical baseline and comparative dataset for evaluating air emissions, specifically Volatile Organic Chemicals (VOCs), associated with the most widely used CIPP technologies (four resins and three curing methods), to identify potential VOC exposure pathways to workers and/or the general public.
