Abstract:

Hydrocarbon-contaminated soil is distributed heterogeneously at McMurdo Station, Antarctica, which has served for over 60 years as the logistics hub for the U.S. Antarctic Program. Here we investigated the treatability of McMurdo Stations contaminated soil with chemical oxidation. Our study collected five soil samples in 2018 and 2019, of which two contained high levels 100 mgkg of total petroleum hydrocarbons TPH suitable for the treatability study. One soil ITC was characterized by 1250 mgkg of predominantly midrange n-C8 to n-C16 hydrocarbons, and the other Soil Pile was characterized by 3500 mgkg of predominantly heavy molecular weight n-C21 hydrocarbons. We investigated the treatability of these soils with both Fentons Reagent pH 3 with Fe2 and modified Fentons Reagent chelated Fe2 , each with hydrogen peroxide concentrations of 3 and 10. Soil slurries were placed on a shaker table at 100 rpm and 4C for up to 21 days. TPH concentrations were reduced by approximately 50 for ITC however, the oxidative treatments did not out-perform controls. All treatments and controls yielded no significant reduction in Soil Pile TPH. Poor performance by these chemical oxidation treatments indicates that remediation of hydrocarbons at these sites may require further soil processing in combination with chemical oxidation or alternative treatment technologies.
