Heavy metal pollution in the Yamuna River water in the Mathura region was assessed during the summer season at five sampling sites, namely M1, M2, M3, M4 and M5. The mean concentrations of heavy metals followed the order: Zn (1860 μg L⁻¹) > Fe (1222 μg L⁻¹) > Pb (656 μg L⁻¹) > Cd (254 μg L⁻¹) ≥ Mn (158 μg L⁻¹) > Cu (116 μg L⁻¹) > Ni (96 μg L⁻¹) > Cr (70 μg L⁻¹). Among these, Fe, Pb, Ni, and Cr were found to be within the permissible limits for irrigation water at all sites, whereas Cd, Zn, Cu, and Mn exceeded the permissible limits at certain locations. The mean Heavy Metal Pollution Index (HPI) indicated that site S4 exhibited the highest level of contamination. The overall mean HPI value for the Yamuna River during summer was 2035, which is significantly higher than the critical limit of 100, indicating severe pollution. Similarly, the Metal Quality Index (MQI) was highest at site M4 (75), while the average MQI for the river was recorded as 30. Pearson’s correlation analysis revealed a significant positive correlation among all the studied heavy metals, suggesting a common point source of pollution.
