 Cured in place pipe is one of the most popular water pipe repair technologies in the U.S. When you steam cure CIPP, you basically pump steam in to be in contact with this raw chemical and it hardens. Some of that materials then exits out the pipe or ranhole and goes into the environment. This National Science Foundation rapid response study that we conducted was intended to evaluate what types of materials were created and emitted by cured in place pipe sites into the air. What we discovered was that the materials being emitted from CIPP sites went against many of the assumptions that have been claimed about the technology for years. That white stuff isn't just steam. It actually is organic vapors, a multitude of different organic compounds. Some of them are known carcinogens and endocrine disrupting compounds. This technology is being used in 50% of all water pipe repairs in the United States. We need to immediately understand the short and long-term impacts of these exposures to the workers and possibly to the general public. If there are these types of impacts, we need to institute operational changes or technology changes to protect the workers and protect the public from these exposures.
