Abstract

Coal mining activities exacerbate water contamination and scarcity in the vicinity of the respective region. In this study, a regional water poverty index (WPI) model was developed to assess the water stress situation of Dhanbad Municipal Corporation (DMC). The groundwater quality of DMC was assessed by collecting samples from 17 spatially distributed GIS-based locations. The cationic and anionic chemistry of groundwater showed the dominancy calcium (Ca²⁺) followed by magnesium (Mg²⁺) > sodium (Na⁺) > potassium (K⁺), and sulphate (SO₄²⁻) followed by chloride (Cl⁻) > nitrate (NO₃-) > fluoride (F⁻), respectively. Furthermore, the spatial distribution of heavy metals and hydrogeochemical facies was investigated using ArcGIS 10.3 (MAP) and Origin (version 3.7) analytical tools. The concentration of Fe in groundwater of DMC varied from 216 to 2699 µg/L, surpassing BIS’s guideline value (300 µg/L). The estimated non-carcinogenic risks based on hazard index (HI) value were found to be higher in children (1.07E-01 to 5.55E-01) than in adults (1.04E-01 to 2.24E-01). The result of the present study is important for designing remediation scenarios for water scarcity and contamination in mining regions.

印度东部丹巴德市政公司（DMC）区域水贫困指数（WPI）模型的开发和评估

煤矿开采活动加剧了相关地区附近的水污染和缺水问题。本研究建立了区域水贫困指数（WPI）模型来评估丹巴德市政公司（DMC）的水资源压力状况。利用地理信息系统（gis）对17个空间分布地点的地下水水质进行了评价。地下水的正离子化学和阴离子化学分别以钙（Ca2+）为主，其次是镁（Mg2+） >；钠（Na+） >；钾（K+）；硫酸盐（SO42−）为主，其次是氯化物（Cl−）>；硝酸盐（NO3-） >；氟（F−）。利用ArcGIS 10.3 （MAP）和Origin（3.7版）分析工具对重金属空间分布和水文地球化学相进行了研究。DMC地下水中铁的浓度在216 ~ 2699µg/L之间，超过了BIS的指导值（300µg/L）。基于危害指数（HI）值估计的非致癌风险发现儿童（1.07E-01至5.55E-01）高于成人（1.04E-01至2.24E-01）。本研究结果对设计矿区水资源短缺和污染的补救方案具有重要意义。
