NASSCO responds to Purdue University’s CIPP findings

The National Association of Sewer Service Companies (NASSCO) has responded to Purdue University’s findings on cured-in-place pipe (CIPP), refuting the report’s link between exposure to styrene and cancer in humans.

Purdue University Assistant Professor of Engineering Dr Andrew J. Whelton recently released a report, completed by his students, titled ‘Worksite Chemical Air Emissions and Worker Exposure during Sanitary Sewer and Stormwater Pipe Rehabilitation Using Cured-in-Place-Pipe (CIPP)’.

Published on 26 July 2017 in the Environmental Science & Technology Letters, a publication of the American Chemical Society, NASSCO said it is clear that the guidelines and specific quality and safety protocols were not utilised during the testing performed, nor referenced in the study by the university.
