Abstract: The present study had assessed the level of heavy metal contamination in wastewater collected from industrial and mining areas of Dhanbad, Jharkhand, India. Wastewater samples had been analyzed for concentrations of lead (Pb), cadmium (Cd), chromium (Cr), manganese (Mn), copper (Cu), and zinc (Zn) using standard analytical techniques. The results had revealed that most metal concentrations had exceeded the permissible limits prescribed by WHO (2017) and BIS (2012), particularly in regions located near coal washeries and mining dumps. Spatial variations in contamination had indicated the direct impact of anthropogenic activities such as coal processing, industrial discharges, and poor wastewater management. These findings had been consistent with global observations from industrial zones in countries like China, Ghana, and Brazil, suggesting a common environmental challenge. The study had highlighted the pressing need for sustainable wastewater treatment technologies, including bioremediation, membrane filtration, and metal recovery systems. The research had served as a baseline for future environmental risk assessments and had called for stringent regulation, public awareness, and improved industrial accountability to ensure the protection of ecological and human health in the region.
