ISOTEC, with over 13 years of ISCO experience, has successfully demonstrated treatment of 1,4-dioxane in laboratory experiments. An initial laboratory test produced a 99%+ reduction in a field sample spiked 1,4-dioxane (see table 1). The result suggested that ISOTEC’s patented modified Fenton’s technology can achieve similar reductions under field conditions. An international environmental consultant, encouraged by the initial laboratory test, commissioned a comparative benchscale test using a client’s soil sample that contained concentrations of VOC’s, lindane and 1,4-dioxane (see table 2). The results of this laboratory test confirmed the previous test results and concluded the ISOTEC modified Fenton’s process is successful in treating 1,4-dioxane to levels below regulatory MCL’s.
