| This fact sheet, developed by the U.S. EPA Federal Facilities Restoration and Reuse Office (FFRRO), provides a brief summary of the emerging contaminant 1,4-Dioxane, including physical and chemical properties; environmental and health impacts; existing federal and state guidelines; detection and treatment methods; and additional sources of information. 1,4-Dioxane is a probable carcinogen and has been found in ground water at sites throughout the United States. The physical and chemical properties and behavior of 1,4-Dioxane create challenges for its characterization and treatment. It is highly mobile and has not been shown to readily biodegrade in the environment. This fact sheet is intended for use by site managers faced with addressing 1,4-Dioxane at cleanup sites or in drinking water supplies and for those in a position to consider whether 1,4-Dioxane should be added to the analytical suite for site investigations. |
