1,4-Dioxane is a solvent stabilizer frequently found at contaminated sites where methyl chloroform (1,1,1-trichloroethane) was used for degreasing. This report profiles the occurrence and properties of 1,4-dioxane and provides a summary of the available remedial technologies. The information presented should prove useful to project managers and other regulatory officials who oversee cleanup of contaminated groundwater, particularly where chlorinated solvents are the principal contaminant. Consultants, including hydrogeologists, remediation engineers, and modelers, should also find this report useful, as should water utility operators and regulators.
