1,4-dioxane is a synthetic chemical used in a variety of industries and produced as a byproduct or impurity in household and industrial products.
It was detected above 0.35 µg/L (the 10-6 cancer risk level) in approximately 7% of the drinking water systems during the USEPA's Third Unregulated Contaminant Monitoring Rule (UCMR3), the second highest exceedance frequency among the contaminants monitored in UCRM3. The only effective treatment technology is the advanced oxidation process (AOP). The industry (particularly small systems in rural areas) needs an alternative treatment technology and this presentation will describe the proof of concept for metabolic treatment of 1,4-dioxane in drinking water by biofiltration.
