“…The risk of groundwater contamination by leachate is determined by many factors, including precipitation, hydrogeological conditions of the area, the toxicity, concentration and chemical composition of contaminants, solid waste composition, degree of compaction, absorptive capacity of the waste, landfill chemical and biological activities, landfill temperature, age of waste, and depth and distance from the pollution source or the direction of groundwater flow [6][7][8][9][10][11][12][13][14][15].…”

Abstract:The purpose of the present paper is to assess groundwater contamination by ammonium originating from the waste management site (including composting plant and the landfill) located in the vicinity of protected areas. In this paper, the impact of urban and industrial facilities adjacent to the landfill is also investigated. The analysis of ammonium concentration was carried out for selected piezometers and then the monitoring and laboratory tests results were referred to the Polish standards of groundwater quality. The content of the paper discusses the changes of ammonium concentration in time and space and presents potential reasons for these changes, especially resulting from the construction of the vertical bentonite barrier. The results show the significant decrease of ammonium concentration and progressive improvement of water quality observed in almost every piezometer after a few years since the vertical barrier has been installed. Furthermore, the paper provides statistical analyses of groundwater monitoring data from the period 1998-2015 in order to control the groundwater quality and assess the movement of contamination plume in the landfill area.

“…Further more, the generated biogas from solid waste is released into the atmosphere as a result of bio-decomposition of organic matter in the solid waste (Iaconi et al 2006;Bicheldey and Latushkina 2010) by the incoming flowing water and temperature prevail within the solid waste. Due to the settlement of very fine organic matter within the solid waste, drained-out leachate from the solid waste and removal of biogas/air from the pores of the solid waste, self compaction/consolidation took place.…”

“…Municipal solid waste includes wastes which are generated from residential, commercial, industrial and institutional sectors (Pankaj and Prakash 2011). After land filling, solid waste undergoes physico-chemical and biological changes (Ehrig 1984), and when the percolating water such as rain fall, irrigation and moisture content of solid waste, the more contaminants in the form of liquid (leachate) are leached (Hamzeh et al 2009) and landfill gases are evolved (Iaconi et al 2006;Bicheldey and Latushkina 2010). The rate of generation of leachate and the time taken by leachate to reach the surface and groundwater bodies depend on the movement of leachate through the solid waste (Sivakumar 1999;Sivakumar and Thandaveswara 2004;Thandaveswara and Sivakumar 2004).…”

An extensive use of solid-waste landfills for disposal of municipal and industrial wastes have prompted increased attention to groundwater pollution caused by leachate generated in such landfills. The potential for groundwater contamination by leachate has necessitated engineering designs for landfills. The quantity of leachate generated from the solid waste and the movement of water through the solid waste depends on water input and the solid-waste characteristics. This paper dealt with the experimental investigations using the laboratory solidwaste leaching column to estimate the total leachate volume/leachate flow for unsaturated and saturated conditions. The hydraulic properties of the solid waste like initial moisture content, field capacity, permanent wilting point, saturation moisture content, effective void ratio, saturation hydraulic conductivity and saturation suction pressure were determined from the small-scale laboratory experiments, which are the input for analytical model study of leachate flow/total leachate volume for both unsaturated and saturated conditions. The result of analytical model study was compared with the results of experimental investigations. Comparisons of measured and computed total leachate volume/leachate flow using Darcy's law showed reasonable agreement.

“…The composition of landfill leachate, the amount generated and the extraction of potential pollutants from the waste depend upon several factors, including solid waste composition, degree of compaction, absorptive capacity of the waste and waste age, seasonal weather variations, levels of precipitation, Landfill temperature, size, hydrogeological conditions in the vicinity of the landfill site, engineering and operational factors of the landfill, pH, landfill chemical and biological activities [7]. A simplified water balancing equation takes all of these factors into account and allows designers to predict an amount of leachate that will be produced by the landfill.…”
