摘要

本研究旨在探索和了解地下水水化学，利用水质指数(Water quality Index, WQI)和统计相关性对Athgarh流域地下水水质进行综合评价。因此，为饮用目的对地下水的质量进行了评价。此外，通过系统采集地下水样本并进行系统的理化分析，连续两年监测了水质的季节变化和年变化。在计算水质指数时，考虑了13个参数(即pH、EC、总溶解固体、总硬度、钙、钠、钾、镁、碳酸氢盐、氯化物、氟化物、硫酸盐和硝酸盐)。将分析值与WHO规定的饮用适宜性限值进行比较。通过Piper的三线性图和Chadha的正阴离子图对水文相进行评价。系统的统计相关研究揭示了不同水质参数对之间的显著线性关系。

GROUNDWATER QUALITY INDEX, STATISTICAL CORRELATION, SEASONAL AND ANNUAL COMPARATIVE HYDROCHEMICAL ANALYSIS OF ATHGARH BASIN, INDIA: AN INTEGRATED EMPIRICAL STUDY

This study aimed to explore and understand groundwater hydrochemistry, evaluate the groundwater quality of the Athgarh basin comprehensively using Water Quality Index (WQI) and statistical correlations. Accordingly, the quality of the groundwater was assessed for drinking purposes. Moreover, seasonal variation and annual variation of water quality have been monitored for two consecutive years after systematic collection of groundwater samples and their methodical physico-chemical analysis. For calculating the WQI, 13 parameters (viz., pH, EC, total dissolved solids, total hardness, calcium, sodium, potassium, magnesium, bicarbonate, chloride, fluoride, sulphate and nitrate) have been considered. The analyzed value is compared with the prescribed limits of WHO for drinking suitability. Hydrological facies were evaluated through Piper’s trilinear diagram and Chadha’s diagram using cation and anion values. A systematic statistical correlation study deciphers the significant linear relationship among different pairs of water quality parameters.
