Investigation of influence of lapes landfill leachate on ground and surface water pollution with heavy metals

Abstract As a result of global and intense production the waste disposal problems become more and more urgent. Waste processing, utilization and recycling is to a certain extent limited by many economic, organisational and technological factors, and this inevitably encourages waste disposal in landfills. Physical, chemical and biological interactions in landfill cell result in formation of landfill gas and harmful leachate. Because of lack of control, together with usual communal waste, industrial waste was also dumped to landfills, therefore gas and leachate produced include large amounts of toxic compounds. Once hazardous waste materials occured in landfills, later they vastly expanded the whole spectrum of toxic materials and compounds. In the landfill environment chemical properties of surface and ground water and concentration of separate components are governed by seepage of leachate and industrial solutants into soil and ground layers and their transport by subsurface waters. Influence on the envir...
