After 15+ years of hydraulic containment and pump-and-treat using an advanced photo-catalytic oxidation system, re-evaluation of available technologies for remediation of a 1,4-dioxane plume was conducted for a historical industrial site in southwestern Ontario. The move from pump and treat to an active chemical oxidation process was supported by the emergence of new technologies and products for active 1,4-dioxane treatment. At least one oxidant, persulfate, has been developed and proven effective for in situ chemical oxidation of 1,4-dioxane. This presentation illustrates the history of the issue and decisions made in 2002, along with a new technology evaluation and selection process implemented in 2018. A cost analysis of the project for the past 20 years and predictions of remediation closure are included. https://2ziapbmm3zh1x23mj335vjxt-wpengine.netdna-ssl.com/wp-content/uploads/2018/12/SMART-Remediation-Calgary-2019-Grant-Walsom.pdf
