Team Leaders: Keisha Long (South Carolina DHEC) & April Lazzaro (Michigan EGLE)
Ethylene oxide (EtO) is a flammable, colorless gas used to make other chemicals for a range of products, including antifreeze, textiles, plastics, detergents, and adhesives. Currently, there are questions about how background EtO should be defined because of mobile source emissions causing disparate levels of EtO in the environment, and there are also various analytical methods available and employed to measure EtO, which yields inconsistency in measurement and management. The ITRC team will explore background EtO to better differentiate between point and nonpoint source emissions, and the various methods used to analyze EtO to create compressive and consistent resources on where, when, and how to analyze and manage EtO.
