Newly updated and comprehensive information related to the investigation and cleanup of 1,4-dioxane is now available from the Interstate Technology Regulatory Council (ITRC).

View the fact sheets and guidance documents on ITRC’s website.

1,4-Dioxane has been used as a solvent stabilizer since the 1950s. The widespread use of solvents through the 1980s suggests the potential for 1,4-dioxane to be present at thousands of solvent sites in the U.S.; however, it is not always included in the standard analytical compound list and may not have been tested at many of these sites. The U.S. EPA has classified 1,4-dioxane as a likely carcinogen.

Environmental professionals will find the above-linked information useful to increase knowledge of 1,4-dioxane history and potential sources, the federal regulatory framework, environmental fate and transport, investigation strategies, sampling and analysis, toxicity and risk assessment, and remediation and treatment technologies.

ITRC also offers online training, beginning with a seminar on March 25 from 12-2:15 p.m. CT on the Science, Characterization & Analysis and Remediation of 1,4-Dioxane.

Webinar registration and more information is available on the ITRC website.
