1,4-DIOXANE: ANALYSES AND REMEDIATION

Because of its widespread use, 1,4-dioxane is typically found at chlorinated solvent sites that have 1,1,1-TCA or TCE impacts and at unlined landfill sites.  No maximum contaminant level (MCL) has yet been set for 1,4-dioxane by EPA; however, a few state agencies have established state-specific concentration standards or guidance values.  

1,4-dioxane has several unique properties that make it difficult to characterize and remediate. In this session we will share our experience and lessons learned from working on sites where 1,4-dioxane was present, and walk you through the site characterization, data validation, and remediation technology screening and implementation process.  

If you are curious about characterization and treatment of emerging contaminants like 1,4-dioxane, this session is for you. It includes a comparative evaluation of differing analytical methods, bench-scale testing of oxidant technologies, and planned field scale testing of ozone in a complex hydrogeologic environment.
