Research Team and Collaborators
The CIPP Solutions Group is an informal cadre of collaborators working to understand and develop solutions for one of the most globally popular pipe repair technologies called CIPP. CIPP, which is known as cured-in-place-pipe, is considered a “trenchless” pipe repair method. This process enables contractors to repair a buried water or sewer pipe without diging up and replacing the existing damaged pipe. This practice involves the chemical manufacture of a new plastic pipe inside the existing damaged pipe. CIPP technology is also increasingly being used for plumbing repair inside buildings.
The purpose of the CIPP Solutions Group is to minimize human health and environmental risks associated with cured-in-place-pipe (CIPP) technology and provide stakeholders information about chemical incidents and exposures that occur. CIPP use has been associated with a variety of significant human health and environmental consequences. These consequences including fish kills, injuries to children and adults, an explosion, and contaminated buildings, among others, have been associated with the improper chemical handling, improper waste management and disposal, improper or lack of safety warnings for workers and the public, and misinformation spread about the practice.
Studies supporting one or more of these members on cured-in-place-pipe technology, worker and public safety, and environmental issues have been funded by the US National Science Foundation (NSF.gov), US National Institutes of Health / National Institute of Environmental Health Sciences (NIEHS.gov), US Environmental Protection Agency (EPA.gov), US Federal Highways Administration (FHWA.gov), and Virginia Department of Transportation (VDOT.gov).
Information on this site is provided for and has been used by law enforcement, members of the public, physicians, emergency responders like firefighters and police, local, county, state, and federal government health officials, CIPP workers, and researchers.
