Abstract

Freshwater is an important natural resource for sustaining human life. The study explores the hydrochemical characteristics, water quality status and irrigation suitability of 13 surface-water reservoirs in the Junagadh District of Saurashtra Peninsula, Gujarat state, India, in pre-monsoon 2025. APHA (2017) protocols and standard values of WHO-2017 and BIS-2012/2015 were used throughout the analysis. In water quality index (WQI), 84.62% of the samples fall within the good category and 15.38% within the excellent category for domestic purposes. Sodium adsorption ratio (SAR), the sodium percentage (Na%) and residual sodium carbonate (RSC) were evaluated for irrigation suitability. In the USSL plot, most samples were in the C2S1 category, indicating low sodium hazard; few show moderate salinity. In Piper diagram, Ca2+–Mg2+–HCO3– and Ca2+–Mg2+–Cl– are dominant facies. Rock weathering is a geochemical process primarily identified by the Gibbs diagram. Based on the findings, the surface waters of Junagadh District are suitable for both domestic use and irrigation applications.
