Effects of Self-protection of Natural Ecosystems on the Example of Artificial-Natural Geochemical Barriers in Landfills of North-Western Russia

For Nature any landfill is foreign and aggressive object, it impairs and pollutes atmosphere, soils, grounds, surface waters and groundwater. Usually these environments are taken as bearing invariable natural characteristics and so under artificial impacts they need in artificial protection. The most expansive efforts in this usually are targeted to groundwater, mainly it is construction of waterproof screens around waste masses. But our numerous data from landfills in the North-Western Russia allow to conclude that the pollution of groundwater when compare to surface waters is always insignificant and does not depend nor on a size of the landfill, nor on a time of its operation, and even nor on ground conditions, because of the widespread natural development of geochemical waterproof barriers in grounds under the influence of leachate. This is the prominent example of the self-protection of the environment against an aggressive object according to Le Chatelier principle and to the ideas of biogeochemical energy of Vernadsky.
