Abstract Groundwater is an important source for drinking and irrigation purposes. Due to anthropogenic activities, heavy metals have been leaching due to industrial waste and agricultural activities to the groundwater causing pollution. The assessment of groundwater quality is necessary to reduce the pollution to acceptable levels. Therefore, the aim of this study is to investigate heavy metal concentrations in the groundwater of the villages of Garautha Tehsil, Jhansi where the anthropogenic activities are active. The groundwater samples were analyzed by inductively coupled plasma – mass spectrometry (ICP-MS) and the results were compared to the 2012 Bureau of Indian Standard limits. Three multivariate statistical methods were used to analyze the groundwater quality for irrigation and drinking purposes and to investigate the geological and hydrogeological processes. The results of principal component analysis (PCA) identified four factors responsible for the data structure by illuminating the total variance of 77.83% of the dataset. The majority of groundwater samples contained Al, Co, Cu, Mn, Ni, Cr, Pb, and Fe within the acceptable limits except at few locations. However, the Al, Fe, and Mn concentration were high at a few sites due to rock–water interactions, whereas the concentration of As, Cd, and Zn were lower than their respective permissible limits in all groundwater samples. Furthermore, the groundwater quality for the use of irrigation is found to be acceptable at 19 locations, with only one high result.

印度占西区 Garautha Tehsil 灌溉和饮用地下水中重金属的多元调查

摘要 地下水是饮用和灌溉的重要来源。由于人为活动，工业废物和农业活动导致重金属浸出到地下水中，造成污染。地下水质量评估对于将污染降低到可接受的水平是必要的。因此，本研究的目的是调查人为活动活跃的占西 Garautha Tehsil 村庄地下水中的重金属浓度。地下水样品通过电感耦合等离子体质谱法 (ICP-MS) 进行分析，并将结果与​​ 2012 年印度标准局的限值进行比较。三种多元统计方法被用来分析灌溉和饮用地下水的水质，并调查地质和水文地质过程。主成分分析 (PCA) 的结果通过阐明数据集 77.83% 的总方差，确定了负责数据结构的四个因素。大多数地下水样品中的铝、钴、铜、锰、镍、铬、铅和铁的含量都在可接受的范围内，少数位置除外。然而，由于岩水相互作用，少数地点的 Al、Fe 和 Mn 浓度较高，而所有地下水样品中 As、Cd 和 Zn 的浓度低于其各自的允许限值。此外，发现用于灌溉的地下水质量在 19 个地点是可以接受的，只有一个结果高。
