1,4-Dioxane (14DX-1)
March 2020

About the Resources:

ITRC's 1,4-Dioxane produced factsheets, a guidance document, and training curricula that reviews the technical knowledge and regulatory barriers to meet these needs. To address 1,4-dioxane contamination, some states devised health standards or regulatory guidelines for drinking water and/or groundwater standards. However, many states did not have the necessary guidance these implement standards or guidelines and expressed the need for input on 1,4-dioxane site assessment, detection, monitoring, and remediation.

Team Background:

1,4-Dioxane is a likely human carcinogen that has been used in food additives and laboratory and manufacturing processes. It is also a byproduct of many chemicals used in household products, personal care products, plastics, and polyester, and from the 1950s to 1996, 1,4-dioxane was commonly used in chlorinated solvents. 1,4-dioxane is released into the surrounding environment from wastewater discharge, unintended spills, leaks, historical disposal practices of host solvents, and unregulated manufacturing waste streams. These releases impact groundwater sites and potable drinking water sources across the country. At the time, there were no federal regulations for 1,4-dioxane, so it was often overlooked as a contaminant of potential concern.
