Assessment of Groundwater Quality and Health Risks in Bardsir Plain (Iran) Using WQI, TOPSIS, and CDI-HQ
Abstract This study presents a novel, integrated framework for the holistic assessment of groundwater security in semi-arid regions, utilizing a nine-year, high-resolution dataset from Iran’s Bardsir Plain. The novelty stems from its comprehensive integration of hydrochemical analysis, multi-index evaluation, decision-support modeling, and quantitative health risk assessment. Hydrochemical analysis, employing Gibbs diagrams and Chloro-Alkaline indices, indicates that groundwater composition is primarily controlled …
