Sponsorship Opportunity - CIPP Emissions Study

NASSCO’s mission to set standards for the assessment, maintenance and rehabilitation of underground infrastructure includes making sure safety is priority number one. Recent reports have questioned the safety of the CIPP process, specifically the use of styrenated resins with steam curing of the product. The primary report we are responding to was published in July 2017 by Purdue University, and is titled Worksite Chemical Air Emissions and Worker Exposure during Sanitary Sewer and Stormwater Pipe Rehabilitation Using Cured-in-Place Pipe (CIPP).


NASSCO is conducting a formal review of the Purdue study, as well as other studies on the topic, to include additional sampling and analysis of emissions during the field installation of CIPP using the steam cure process. Research will be peer-reviewed to challenge or confirm the Purdue report. We will honor the findings and act accordingly.


NASSCO has awarded the review to the Center for Underground Infrastructure Research and Education (CUIRE) at the University of Texas at Arlington. The overall goal of this two-phase project is to evaluate the potential release of organic compounds during pipe rehabilitation using the steam cure CIPP method. Potential impacts on health will be assessed and policies will be recommended to protect construction workers, the public, and the environment. You can learn more at nassco.org.



This is a major undertaking, and we need the industry to come together to make sure we keep safety our #1 priority! If you have any questions, please contact Mayank Khurana at 410-442-7473 or [email protected].
