TRANSPORT AND ADSORPTION OF POLLUTANTS IN SATURATED POROUS MEDIA: INTEGRATION INTO UNLIMITED DOMAINRAFFAELE DI PILLO AND MARIA TERESA TODISCO DICEAAAbstract Adsorption and accumulation of persistent pollutants in soils, where the adsorption capacity of the soil itself is exhausted or unusual leaching or erosion events occur, may cause local groundwater degradation. In recent years, subsurface hydrological investigations, due to the increasing interest in site rehabilitation have shown a fast growth. Starting from the classical theories that preside over the phenomena of transport and transformation of pollutants in saturated porous media, the paper presents a direct integration approach of the transport equation over unlimited one-dimensional domains, valid for linear processes, which lead to many situations of practical interest. Lastly results are given as a function of three a-dimensional numbers. |
