The current study aims to assess the risk in humans due to six heavy metals, namely zinc, iron, copper, cadmium, arsenic, and lead, present in the tanker water supplied in the rural area of Bangalore called Kudlu village. Water samples were analyzed for a total period of 18 months between September 2021 to February 2023. Physicochemical and microbiological parameters were assessed for the collected water samples that included 04 tanker water and 01 purified water. Chlorine, pH, alkalinity, cyanuric acid, total hardness, conductivity, temperature, sodium, potassium, total dissolved solids, calcium, and magnesium was taken into consideration. Further bacteriological contamination by E.coli was also tested. Water Quality Indices were calculated based on these parameters. Water quality indices of the tanker water samples indicated that the quality of water was not suitable for drinking. The indices like exposure frequency, Hazard coefficient, carcinogenic and non-carcinogenic risks were calculated for both adults and infants for these heavy metals. The results indicated that the heavy metal concentration observed during the studied time period poses no risk to human health.

目前的研究旨在评估班加罗尔库德鲁村农村地区供应的水罐水中存在的六种重金属（即锌、铁、铜、镉、砷和铅）对人类的风险。对2021年9月至2023年2月期间总共18个月的水样进行了分析。对收集的水样（包括04罐车水和01纯化水）进行了理化和微生物参数评估。考虑了氯、pH、碱度、氰尿酸、总硬度、电导率、温度、钠、钾、总溶解固体、钙和镁。还测试了大肠杆菌的进一步细菌污染。水质指数是根据这些参数计算的。罐车水样水质指标显示，水质不适合饮用。计算了成人和婴儿这些重金属的暴露频率、危害系数、致癌和非致癌风险等指数。结果表明，研究期间观测到的重金属浓度对人体健康不构成风险。
