We report the soil microbial diversity and functional aspects related to degradation of recalcitrant compounds, determined using a metagenomic approach, in a landfill lysimeter prepared with soil from Ghazipur landfill site, New Delhi, India. Metagenomic analysis revealed the presence and functional diversity of complex microbial communities responsible for waste degradation.

Landfill has been recognized as the cheapest form for the final disposal of municipal solid waste and as such has been the most used method in the world. However, siting landfill is an extremely complex task mainly due to the fact that the identification and selection process involves many factors and strict regulations. For proper identification and selection of appropriate sites for landfills...

The biological conversion of sulfate from disposed gypsum drywall to hydrogen sulfide (H(2)S) in the anaerobic environment of a landfill results in odor problems and possible health concerns at many disposal facilities. To examine the extent and magnitude of such emissions, landfill gas samples from wells, soil vapor samples from the interface of the waste and cover soil, and ambient air sample...

Major environmental concerns of municipal landfills revolve around quantity and quality of leachate, gas generation, and decomposition processes occurring therein. Minimizing the time period for maximum biodegradation to reduce leachate and gas emissions after landfill closure, ease the requirement of leachate treatment, and reclamation of landfill site is the most sought after managers proposi...

On the basis of DRASTIC model index system, combined with actual situation in Horqin district Tongliao City, this paper removed influence topography, added land use effects, modified new DRASLIC, used analytic Hierarchy Process (AHP), and calculated evaluation results. Groundwater management protection decisions area provide a reliable for application to design groundwater monitoring network, s...

The availability of virgin soils and traditional landfill covers are not only costly and increasingly becoming scarce, but they also reduce the storage capacity of landfill. The problem can be overcome by the utilisation of certain suitable waste streams as alternative landfill covers. The objective of this study was to assess the suitability of Construction & Demolition fines (C&D), Commercial...

Gases released from landfill sites into the atmosphere have the potential to cause olfactory nuisances within the surrounding communities. Landfill sites are often located over complex topography for convenience mainly related to waste disposal and environmental masking. Dispersion of odours is strongly conditioned by local atmospheric dynamics. Assessment of odour impacts needs to take into ac...

Abstract Choosing a suitable location for the disposal of municipal solid waste is an important environmental problem. Thus, locating landfill has been very important. Leachate from causes contamination groundwater. However, process complicated and based on qualitative quantitative criteria. Therefore, in this paper, hybrid approach determining optimal presented. Additionally, present study att...
