Implication

Environmental assessment demonstrates moderate-to-good irrigation suitability with seasonal sodicity risks in river basin waters, suggesting treated wastewater can support salt-tolerant crops.

Key Points

To assess the hydrochemical, microbiological, and heavy metal characteristics of treated wastewater effluent and receiving river water to determine its suitability for agricultural irrigation.
Collected seasonal samples in 2024 from three sites: wastewater treatment plant effluent, a river mixing zone, and a downstream station.
Measured physicochemical markers, bacteriological indicators, and heavy metals (Cr, Cd, Fe, Pb, Zn), while computing irrigation indices including SAR, Na%, RSC, MH, PI, KR, and IWQI alongside ANOVA and PCA statistical analyses.
Water quality parameters spanned across seasons: TSS = 5–124 mg/L, BOD₅ = 5.6–36 mg/L, COD = 28–169 mg/L, EC ≈ 1271 µS/cm, and TDS ≈ 635 mg/L.
The Irrigation Water Quality Index (IWQI) ranged from 46 to 74, indicating generally moderate to good suitability for irrigation despite seasonal sodicity risks.
