ESTCP Project ER-201324, 73 pp, 2018

This study demonstrated the use of slow-release chemical oxidant cylinders to treat a plume containing 1,4-dioxane and chlorinated VOC constituents. Unactivated persulfate embedded in a slow-release paraffin wax formulation was emplaced in two 4-inch wells housed inside 18-inch diameter boreholes. The objectives were to demonstrate/evaluate the technology effectiveness, sustainability/ longevity, oxidant transport and destruction, implementability/secondary water quality impacts, and technology reproducibility. The demonstration met the majority of the performance objectives. https://www.serdp-estcp.org/content/download/47863/456084/file/ER-201324%20Cost%20&%20Performance%20Report.pdf
