The Cured-In-Place Pipe (CIPP) process has a track record of more than 50 years. It has a demonstrated success record for the trenchless rehabilitation of underground linear infrastructure. As the name implies, the process involves inserting a flexible liner into... Read More

This is the second in a series of articles by NASSCO’s Technical Advisory Council (TAC) discussing the health and safety aspects of styrene in cured-in-place pipe (CIPP) method renewal. While the initial article reviewed the history of styrene use and... Read More

The topic of styrene safety has garnered a lot of attention in recent years. For more than a decade the effects of styrene cure water and condensate have been documented on receiving waters. Since 2017 academic research and customer concerns... Read More

In our first article on this subject, the focus was on the use of the photoionization detector (PID) when sampling styrene levels in the air on CIPP job sites. In this article, we focus on several other techniques that can... Read More

There has been a lot of misinformation and questions recently regarding CIPP job sites and testing for styrene. This article will strive to help CIPP companies better understand the use of the Photo-Ionization Detector (PID) when sampling job sites. Read More
