TLDR
In this article, a case study on assessing the physiochemical characteristics of landfill leachate generated from a municipal solid waste dumpsite in Sri Lanka is presented, where the authors discuss the best management practices.Abstract:
Landfills are one of the most historical and ordinary methods of waste disposal and still remain in many parts of the world. Landfill leachate from open dumpsites has become a crucial environmental issue. Still, the predominant waste disposal method in many developing countries is open dumping, which leads to the generation of significant amounts of leachate mostly to nearby water bodies. Landfill leachate treatment is not an easy task, specifically because of its uniqueness depending on climate, culture, age of the dumpsite, and waste characteristics. Acetogenic leachate characteristics are extremely variable and difficult to predict. However, landfill leachate in the methanogenic phase possesses quite stable characteristics. Herein, we report qualitative and quantitative data on landfill leachate from different parts of the world and discuss the best management practices. In addition, we provide a case study on assessing the physiochemical characteristics of landfill leachate generated from a municipal solid waste dumpsite in Sri Lanka. Overall, landfill leachate poses a risk to the environment and effective leachate management is vital to avoid environmental deterioration.read more

Biogeochemistry of landfill leachate plumes
Thomas Højlund Christensen,Peter Kjeldsen,Poul Løgstrup Bjerg,Dorthe Lærke Jensen,J. Christensen,Anders Baun,Hans-Jørgen Albrechtsen,Gorm Heron +7 more
TL;DR: The literature has been critically reviewed in order to assess the attenuation processes governing contaminants in leachate affected aquifers as discussed by the authors, focusing on dissolved organic matter, xenobiotic organic compounds, inorganic macrocomponents as anions and cations, and heavy metals.

Environmental Impacts of Solid Waste Landfilling
TL;DR: An overview of gas and leachate formation mechanisms in landfills and their adverse environmental impacts, and control methods to eliminate or minimize these impacts is presented in this paper. But the authors do not consider the potential health hazards, such as fires and explosions, vegetation damage, unpleasant odors, landfill settlement, ground water pollution, air pollution and global warming.

Leachate Characterization and Assessment of Groundwater Pollution Near Municipal Solid Waste Landfill Site
TL;DR: The moderately high concentrations of Cl−, NO−3, SO2−4, NH+4, Phenol, Fe, Zn and COD in groundwater likely indicate that groundwater quality is being significantly affected by leachate percolation, and demand for the proper management of waste in Delhi.

Leaching of heavy metals from contaminated soils using EDTA
TL;DR: The results suggest that the lability of metals in soil, the kinetics of metal desorption/dissolution and the mode of EDTA addition were the main factors controlling the behaviour of metal leaching with EDTA.
