ABSTRACT. Leachate Dynamics from Municipal Jerubaiciai Landfill: Management and Clarification. Landfilling is currently a primary method for solid waste disposal. The proximity of many of these landfills to metropolitan wa-ter supplies, the frequency of landfill leachate contamination of groundwater sources, and the knowledge that leachate from landfills may be an important source of ground water pollution and urgent environmental problem. This paper describes leachate formation mechanism, summarizes leachate quality indicators. The aim of this article is to analyse Jerubaiciai landfill leachate management and dynamics of process and influence of main factors causing this problem. The ref-erence periods cover all seasons. Leachate generation rates were monitored from 01/01/2016 to 31/12/2016, landfill receives more than 1050 tons of waste per weak. Chemical analysis was performed on the samples automatically as several parameters as pH, electric conductivity, temperature, pressure. The study found that during the year the amount of leachate from a landfill was ~ 6500 m3 per day. Investigation shows that the leachate electric conductivity content ranges from 590 - 1970 μS/cm. The weather temperature ranged from 13.6 C (early winter period) 23.5 C (late summer period). It was concluded that when the amount of leachate temperature increases, the amount of leachate electric conductivity content also in-creases.

Keywords: landfill leachate, water pollution, leachate electric conductivity
