Lead concentrations exceeded permissible limits in over 90% of groundwater samples across locations.
Heavy metal pollution index (HPI) identified 21 seriously affected locations in pre-monsoon, and 7 in post-monsoon sampling.
Groundwater analysis utilized atomic absorption spectroscopy (AAS) and geospatial mapping techniques like GIS for contamination assessment.
Findings suggest localized contamination due to industrial clusters, calling for targeted remediation strategies.
