University Study Questions Safety of Steam-Cured Pipe Lining

The National Association of Sewer Service Companies prepares to bring in third party to do further research, cites concerns about ‘inconsistencies’ in Purdue University study

A Purdue University study published in July about the potential release of toxic chemicals during the CIPP process has the National Association of Sewer Service Companies preparing to do its own study.

NASSCO is currently requesting research proposals through October for a third party to do a study, which would include a review of recent publications related to emissions and the CIPP installation process as well as additional sampling and emissions analysis during field installation, specifically using the steam-curing process.
