ABSTRACT
There is proposed philosophy of oxidative-geochemical barrier against dioxin-pollution of groundwater. Oxidative barriers are created by a treatment of the site of the ground-water-aquifer, chosen for this purpose, with oxygen-containing water from the same aquifer. Pumping this water out, saturating it with oxygen (or air) and pumping water with dissolved oxygen back is done through pit-holes. In such geochemical barrier a heterogeneous-catalytic system is created, which is able to oxidize the dioxins. The chemical model confirms this conception. It was shown that in modelling system the dioxin simulator half-life is about 25 hours.
