Improper urbanization and industrialization are causing a critical stress on groundwater quality in urban areas of the developing countries. The present study under investigation describes the pollution caused by leachate from a waste management site in southwestern Bangalore city causing pollution of the surface water and groundwater reserves. The characterization of 20 groundwater samples and Haralukunte lake sample indicated high pollution of these water reserves by leachate entry into the groundwater and surface water sources. The study area focuses around the solid waste management site, carrying out bio-composting and vermi-composting of municipal solid waste. Further investigations on the severe health problems faced by the public in the study area has revealed a clear pointer towards the usage of polluted water for rearing live-stock, farming, and domestic activities. The characterization of the leachate with high values of BOD at 1,450 mg/l, TDS at 17,200 mg/l, nitrates at 240 mg/l, and MPN at 545/100 ml indicates a clear nuisance potential, which has been substantiated by the characterization of lake water sample with chlorides at 3,400 mg/l, TDS at 8,020 mg/l, and lead and cadmium at 0.18 and 0.08 mg/l, respectively. Analysis of groundwater samples shows alarming physicochemical values closer to the waste disposal site and relatively reduced values away from the source of the waste management site. Bureau of Indian Standards have been adapted as the benchmark for the analysis and validation of observed water quality criteria.
城市化和工业化的不当发展正在给发展中国家城市地区的地下水质量带来严重压力。本研究描述了班加罗尔市西南部一个废物管理场地的渗滤液造成地表水和地下水污染的情况。对 20 个地下水样本和哈拉卢肯特湖样本的特征描述表明，渗滤液进入地下水和地表水水源，导致这些水资源受到严重污染。研究区域集中在固体废物管理场地周围，开展城市固体废物的生物堆肥和蚯蚓堆肥。对研究区域公众面临的严重健康问题的进一步调查表明，人们明显地将受污染的水用于饲养牲畜、农业和家庭活动。渗滤液的特征是 BOD 值高达 1450mg/L，TDS 值为 17200mg/L，硝酸盐值为 240mg/L，MPN 值为 545/100ml，表明存在明显的滋扰潜力，这一点通过对氯化物含量为 3400mg/L、TDS 值为 8020mg/L、铅和镉分别为 0.18 和 0.08mg/L的湖水样本的特征描述得到了证实。地下水样本的分析显示，靠近废物处理场的物理化学值令人震惊，而远离废物管理场地的物理化学值则相对降低。印度标准局已被作为分析和验证所观察到的水质标准的基准。
