TL;DR: None of the individual physico-chemical techniques is universally applicable or highly effective for the removal of recalcitrant compounds from stabilized leachate, but adsorption, membrane filtration and chemical precipitation are the most frequently applied and studied worldwide.

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.
Abstract: Leachate and groundwater samples were collected from Gazipur landfill-site and its adjacent area to study the possible impact of leachate percolation on groundwater quality. Concentration of various physico-chemical parameters including heavy metal (Cd, Cr, Cu, Fe, Ni, Pb and Zn) and microbiological parameters (total coliform (TC) and faecal coliform (FC)) were determined in groundwater and leachate samples. The moderately high concentrations of Cl-, NO3(-), SO4(2-), NH4(+), Phenol, Fe, Zn and COD in groundwater, likely indicate that groundwater quality is being significantly affected by leachate percolation. Further they proved to be as tracers for groundwater contamination. The effect of depth and distance of the well from the pollution source was also investigated. The presence of TC and FC in groundwater warns for the groundwater quality and thus renders the associated aquifer unreliable for domestic water supply and other uses. Although some remedial measures are suggested to reduce further groundwater contamination via leachate percolation, the present study demand for the proper management of waste in Delhi.

TL;DR: The levels of bisphenol A in hazardous waste landfill leachates collected in Japan in 1996 were determined by gas chromatograph/mass spectrometer (GC/MS) and some samples exceeded the EC50 or LC50 levels for aquatic biota.

TL;DR: The Fenton process is an important and competitive technology for the treatment or pretreatment of landfill leachate and its initial pH, dosages, aeration, final pH, reagent addition mode, temperature and UV irradiation may influence final treatment efficiency.

TL;DR: In this article, the amount of the organic substances removed by oxidation and coagulation in treatment of the non-biodegradable landfill leachate by Fenton's reagents was analyzed.
