Summary Most of landfill sites which emerged in the Leningrad Region during the last decade are illegal and harmful for the environment. Unavoidably it leads to environmental disaster. Creation of new geochemical barriers as one of the stages of the remediation process also provokes additional anthropogenic load. And due to lack of research it can lead to new environmental problems. Since geological conditions throughout the Leningrad region are similar, it is possible to create a comprehensive model of rehabilitation, based on the results of the monitoring of selected landfi lls. It is crucial to find a new approach, the main aim and distinctive feature of which would be preservation of existing geochemical barriers and minimization of imbalances in self-healing process of natural ecosystems. Rating of paragenetic geochemical associations (the studying of concordance and discordance of elements) helps to create a model of migration and concentration of pollutants which are typical to a certain type of landfills with similar geological and morphological characteristics.
