OPTIMIZED TREATMENT OF 1,4-DIOXANE IN EXTRACTED GROUNDWATER AND REINJECTION FOR AQUIFER REPLENISHMENT
Woodard, S. | New Jersey Water Environment Association 104th Annual Conference- Contaminants of Emerging Concern Across the Water Cycle, 6 May, Atlantic City, 2019

A new 1,4-dioxane groundwater treatment system was installed to replace an aging pump-and-treat system at a site in Santa Fe Springs, California. The replacement technology relies on an AMBERSORB™ 560 resin treatment system to achieve lower operating costs versus the previous system, which was based on an advanced oxidation process, coupled with granular activated carbon. After 18 months of operation, the full-scale Ambersorb system continues to consistently produce non-detect effluent for 1,4-dioxane and VOCs. https://www.aaees.org/_downloadcenter/resources/NJWEA052019-AltOptimizedTreatment.pdf
