Effect of Precipitation on Leachate Parameters Causing Colmatation of Landfill Drainage Layer

Municipal waste landfill drainage formatted at different stages of landfill exploitation, has a negative impact on natural environment. According to the newly implemented waste management policy, landfill drainage monitoring is being performed at solid waste disposal sites. In long time, complicated components of the filtrate destine sedimentation of part of the elements on the drainage layer. In this kind, porosity and layer penetration decrease. The principal elements influencing the decreasing penetration – calcium, iron, manganese and carbonate compounds. Filtration at landfills established from waste humidity and atmospheric precipitation penetrating through the waste. Systematic samples were determined by seasonality. Parameters analysed showed particularly higher values when precipitation amounts are lower and vice versa. Dependency of precipitation was proved by the statistical data analysis made with Pirson’s correlation coefficients
