从加济布尔垃圾填埋场及其邻近地区采集渗滤液和地下水样本，研究渗滤液渗滤对地下水质量可能产生的影响。测定了地下水和渗滤液样品中各种理化参数的浓度，包括重金属（Cd、Cr、Cu、Fe、Ni、Ph 和 Zn）和微生物参数（总大肠菌群 (TC) 和粪便大肠菌群 (FC)）。地下水中 Cl-、NO3-、SO42-、NH4+、苯酚、Fe、Zn 和 COD 浓度中等偏高，可能表明地下水质量正受到渗滤液渗滤的显着影响。此外，它们被证明可以作为地下水污染的示踪剂。还研究了井距污染源的深度和距离的影响。地下水中 TC 和 FC 的存在对地下水质量提出了警告，从而使相关含水层无法可靠地用于生活供水和其他用途。尽管建议采取一些补救措施来通过渗滤液渗透减少进一步的地下水污染，但目前的研究要求德里对废物进行适当的管理。
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, Ph 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-, SO42-, 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.
