There is no need to explain how much a person is dependent on water. City sewage, industrial effluents, oil spills, lenses of polluted groundwater under objects of accumulated harm – cattle burial grounds, storage facilities for caustic chemicals or fuels and lubricants – these are real environmental ulcers of nature, characteristic of any industrialized country.

Therefore, the problem of rehabilitation is approached in a complex manner, based on the groups of pollutants and proven means for their physical and chemical decomposition into less toxic groups, or vice versa, for the formation of stable and weakly mobile complexes.
Elimination of environmental damage to nature is unthinkable without the sanitation of water bodies. The installation of permeable reaction barriers (PRB) refers to physical and chemical methods for treating groundwater, subsurface polluted flows, and spills of hazardous substances.
Blocking filtration barriers localize, isolate and counteract pollutants. Neutralizing reagents are introduced inside the PRB action loop, for example, zero-valence metals, chelates, sorbents, functional microorganisms, etc. The PRB can be of different configurations and include additional elements – trapping pits and ditches, discharge pipelines or wells, system of gateways with intermediate zones with different reactors.
Rain and melt waters are of particular danger, as well as atmospheric transfer of gas and dust emissions into aquifers. Therefore, it’s necessary to systematically monitor traces of migration of highly toxic compounds.
PRB from peat-sapropel mixtures effectively neutralizes compounds of heavy metals and radionuclides, is radiation and chemically stable, allows combination with defoamers, iron-containing granules to trap chlorine pollutants and with other functional reagents.
SatoSoil® improvers are suggested for the task of restoring polluted water bodies.
