Hydrogeochemical Assessment of Groundwater Quality and Suitability for Drinking and Agricultural Use. The Case Study of Fars Province, Iran

This study aims to evaluate the hydrogeochemistry of aquifers in Fars province, Iran, from 2007 2017 and assess groundwater’s suitability for drinking agricultural uses. A total 35,000 samples were collected wells qanats across province. Piper, Gibbs, Durov diagrams used hydrochemical facies processes. Cross plots different ions investigated ion exchange determine effects anthropogenic activities, as well weathering dissolution rocks minerals aquifers. Groundwater quality purposes also assessed using physicochemical parameters including pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Hardness (TH), calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride concentrations. Suitability domestic was by comparing these values with WHO standards. Sodium alkalinity hazards, Adsorption Ratio (SAR), sodium percentage (Na%), Permeability Index (PI), Magnesium Hazard (MH), Residual Carbonate (RSC) irrigation suitability, along plotting Wilcox USSL diagrams.
