Abstract

This study investigates the groundwater quality in the Bhopal district, located in the Madhya Pradesh state of India. The water quality parameters spatial distribution map is created using QGIS Desktop 3.22.16. The research aims to calculate the groundwater suitability for purposes of drinking by collecting 47 samples from various locations within the district. The analysis includes eleven parameters related to groundwater quality, which is pH, Turbidity, Alkalinity, Total Dissolved Solids, Electrical Conductivity, Calcium Hardness, Total Hardness, Magnesium Hardness, Chloride, Sulphate, and Iron. Water Quality Index (WQI) has been computed to classify the ground water quality of the study area. Finally, a correlation matrix has been generated to explore the linear relationships between various water quality parameters, using correlation coefficients (r) as indicators of association. The present study shows that almost 80% of the quality is suitable for drinking, and about 20 % of the quality are under poor quality that needs treatment before consumption and at two locations the quality is very poor that needs urgent treatment.

利用 QGIS 绘制印度中央邦博帕尔地区地下水物理化学特性图

本研究调查了位于印度中央邦博帕尔地区的地下水质量。使用 QGIS Desktop 3.22.16 绘制了水质参数空间分布图。研究旨在通过收集该地区不同地点的 47 个样本，计算地下水是否适合饮用。分析包括与地下水水质有关的 11 个参数，即 pH 值、浊度、碱度、溶解固体总量、电导率、钙硬度、总硬度、镁硬度、氯化物、硫酸盐和铁。通过计算水质指数（WQI），对研究区域的地下水水质进行了分类。最后，利用相关系数 (r) 作为关联指标，生成了一个相关矩阵，以探讨各种水质参数之间的线性关系。本研究显示，近 80% 的水质适合饮用，约 20% 的水质较差，需要在饮用前进行处理，有两个地点的水质非常差，需要紧急处理。
