The disposal of municipal solid waste into the landfills has been recognized as the major source of soil, surface water and groundwater contamination. Municipal solid waste disposal site for the city of Ludhiana, in Punjab, India, has become an overflowing landfill because of the indiscriminate dumping of solid waste at the site. The leachate produced by landfilling site contains a large amount...

among the environmental problems in nigeria is the lack of proper management of municipal solid wastes (msw), which is capable of releasing hazardous chemicals via leachate to the surrounding environment. in this study, the potential toxic effects of raw leachate obtained from aba-eku landfill (aerl) on clarias gariepinus; and the microorganisms that may be present in the leachate were investig...

Pollution resulted from the leachate of the Sanandaj City landfill into Gheshlagh River is an important environmental and health issue, which has endangered the river. Having a population of more than 400,000 and four municipality districts, the solid waste generation rate is approximately more than 300 tons/day in Sanandaj City. The wastes generated are disposed of at the Sanandaj City landfil...

The present study is aimed at characterizing the landfill leachate as well as its impact on the surrounding groundwater in Kolkata, India. Landfill leachate has been seasonally characterized from 2012-2014, indicating the landfill site in methanogenic phase with high contamination of organics, nutrients, salts, and heavy metals. Sixty groundwater samples have been analyzed for twenty two physic...

Landfill leachates, which are potential pollutants, may also carry significant amounts of nutrients that can be recycled by plants. We assessed the nutritional status and yield of wheat ( L.) and properties of a Rhodic Kandiudult soil (depths of 0-10, 10-20, 20-40, and 40-60 cm) after 11 applications of landfill leachate over 4 yr. In the last application, wheat received 0, 32.7, 65.4, 98.1, or...

Landfill leachate emerges as a promising feedstock for microbial fuel cells (MFCs). In the present investigation, direct airbreathing cathode-based MFCs are fabricated to investigate the potential of landfill leachate. Three MFCs that have different cathode areas are fabricated and investigated for 17 days under open circuit conditions. The maximum open circuit voltage (OCV) is observed to be a...

Leachate originating from open refuse dumpsite systems can be delineated through an integration of qualitative and quantitative methods. This study was designed to examine extent of leachate and pollution from one of the numerous open refuse dumpsites in Lagos metropolis. Qualitative assessment was determined using electrical resistivity tomography (ERT), vertical electrical sounding (VES) and ...

A system of vertical wells was evaluated for its potential to add moisture into landfilled waste. Leachate (and groundwater) was added through 78 vertical wells installed at three different depths. The results of injection tests performed over a 17month duration are presented in this paper. A total of 17,700 m of leachate and groundwater were injected over ____hours of operation time. No signif...

Abstract Leachate originating from municipal solid waste landfills poses a serious contamination threat to public health. The study performed bio-physicochemical characterization of leachate two in Oman, i.e., Multaqa landfill (MLL) and Barka (BLL) before after rainfall. Samples were characterized for 92 parameters. Additionally, the pollution index (LPI) was estimated assess expected levels po...

in this paper the risk of heavy metals discharged from the acidic sludge leachate into groundwater in a landfill located in fajr industrial area )garmsar( has been assessed using iwem software. acidic sludge as one of the industrial hazardous wastes is produced during purification of used oil with mienken )acidic( method. the concentrations of heavy metals )cd, ni, co, pb, zn, mn, cu( in the ac...
