Review of the Methods for Analyzing Site Infiltration of Solid Waste Disposal

Abstract

Methods of analyzing the infiltrate of solid waste disposal sites are considered. It is analyzed that in this area it is most appropriate to develop systems for sorting and recycling household waste, but it should be borne in mind that in the realities of modern Ukraine the use of these systems is quite difficult to implement and their implementation may take some time, during which the existing landfills will poison the soil, surface and groundwater and atmosphere. It has been determined that in practice, it is most effective to take measures to reduce the amount of waste generated, as well as to minimize the damage from waste already disposed at landfills and dumpsites and reduce the impact on the soil and water environment. It is obvious that certain methods of infiltrate management, treatment, etc. need to be developed. However, such research should be preceded by a study of the properties of the infiltrate and its formation, because in addition to the relatively environmentally friendly components of landfill leachate, it may contain quite toxic components that cannot be reduced and, in addition to environmental damage, cause irreparable damage to human health. Since the infiltrate is a multicomponent mixture, both biological and physicochemical methods should be used for high-quality treatment. Based on the results of the study, the characterization of leachate samples by 13 indicators is proposed. The most effective methods for analyzing the infiltrate of solid waste disposal sites have been identified: pH, electrical conductivity, redox potential, salt ammonium, sulfate ions, chloride ions, Ni, Mn, Zn cations. The determining criterion for the selection of the most effective methods for analyzing the infiltrate of solid waste disposal sites was the possibility and feasibility of performing a complete analysis of the infiltrate, which affected the overall efficiency of the process.
