Abstract
In most cases, the migration of groundwater from pollution sources takes place in heterogeneous media, the storage of which is mostly determined by nearly impermeable blocks of porous rocks, while the advection takes place through canals of small storage. The exchange between the blocks and the canals is commonly described by Fick’s law for each solution component separately. Nine-component solutions at waste disposal sites at Tomsk and Dimitrovgrad are used as examples to demonstrate the effects arising at such migration and making the results to differ (sometimes, considerably) from those derived from a model of independent diffusion.
