Since 2016, NASSCO has supported independent research to better understand the effects, if any, of styrene used in the cured-in-place pipe process. Research phases 1, 2, and 3 focused on air emissions resulting from steam cure.The current research, Phase 4, focuses on cure water and potential impact of styrene on publicly owned treatment works (POTW). Partnering with Buried Asset Management Institute – International and headed up by Principal Investigator Dr. Tom Iseley, P.E., and Lead Research Engineer Dr. Hanouf M. Alhumaidi, Phase 4 is broken out into three separate tasks:Task 1: International literature review
Task 2: Survey among POTW
Task 3: Lab
