Abstract

Leaching of contaminants from landfill into the soil and water supply is a major concern because of its risks to human health and environment in areas where adequate disposal systems are lacking. The present research work is concerned with the effect of leachate generated from the Patvi landfill site of Ambala district of Haryana state in India on the quality of its groundwater for a period 2021—2022. Groundwater and leachate samples were collected both in pre monsoon (PRM) and post monsoon (POM) period for the estimation of physico-chemical characteristics and heavy metals. The analysis revealed that in research period, most of the parameters concentration except PO₄²⁻, Nickel, lead and zinc were found to decrease after monsoon season in the leachate samples. However, no definite pattern of water quality parameters was observed in the groundwater samples during the two seasons in two years. The concentration of major cations in water samples was found to be in the order of Ca²⁺ > Mg²⁺ > Na⁺ > K⁺, while the anions followed the order HCO₃⁻ > Cl⁻ > F⁻ > SO₄²⁻ > PO₄²⁻. The results of leachate samples concluded that the leachate percolated through the soil and then groundwater of the surrounding area of the landfill site. Seasonal variability demonstrated dilution during the monsoons and better leachate penetration of wells within and nearer area of the site. The findings of this study have implications for applying timely interventions that are leachate collection systems, landfill redesigns, and compliance with SWM Rules, 2016.The study supports the principles of the appropriate Sustainable Development Goal 6 on clean water and sanitation and offers practical implications to enhance landfill conditions and decrease negative impacts in the similar area.

固体废物填埋及其对地下水水质的影响——以印度北部某成熟填埋场为例

污染物从垃圾填埋场渗入土壤和供水系统是一个主要问题，因为它对缺乏适当处理系统的地区的人类健康和环境构成风险。目前的研究工作是关于印度哈里亚纳邦安巴拉区Patvi垃圾填埋场产生的渗滤液对2021-2022年期间地下水质量的影响。在季风前（PRM）和季风后（POM）采集地下水和渗滤液样品，估算其理化特征和重金属含量。分析表明，在研究期间，除PO42−、镍、铅和锌外，其余参数浓度在季风季节后均呈下降趋势。然而，在2年的2个季节中，地下水样品的水质参数没有明确的变化规律。水样中主要阳离子的浓度顺序为Ca2+ >； Mg2+ > Na+ > K+，阴离子的浓度顺序为HCO3−>； Cl−> F−> SO42−> PO42−。渗滤液样品的分析结果表明，渗滤液首先渗透到垃圾填埋场周围的土壤中，然后渗透到地下水中。季节变化表明，在季风期间，渗滤液会被稀释，在场址附近的水井渗滤液渗透得更好。本研究的结果对采用及时的干预措施，即渗滤液收集系统、垃圾填埋场重新设计和遵守2016年的SWM规则具有启示意义。该研究支持了有关清洁水和卫生设施的可持续发展目标6的原则，并为改善垃圾填埋场条件和减少类似地区的负面影响提供了实际意义。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
