Benzene is toxic, but it still has industrial uses. From the article:
> The reactor used by the researchers consists of an undivided electrolysis cell in which dimethyl sulfoxide (DMSO) is used as a solvent
They remove the DDT from the soil into the solvent (itself quite unpleasant). From there, it's pretty easy to filter out the soil and clean it up. Add water and boil or freeze dry to extract it back out, preferably capturing it to be reused.
