In the modern era, industrialization in developing countries like Bangladesh has significantly polluted groundwater systems. Tannery industry effluent is a major source of water pollution. This study focuses on removing heavy metals, specifically lead, and reducing key physicochemical parameters including pH, Electrical Conductivity (EC), Total Suspended Solids (TSS), Dissolved (TDS), Chemical Oxygen Demand (COD), Biochemical (BOD5) from tannery wastewater utilizing phytoremediation potential Vetiveria zizanioides. The experiment was conducted by hydroponic technique, evaluating effects treatment time. Results showed significant pollutant removal efficiencies after 45 days were pH (24.82%), EC (36.74%), BOD5 (87.07%), COD (84.89%), TSS (84.02%), TDS (73.39%), Lead (66.13%). Vetiver revealed strong growth 95% survival rate. Post-treatment levels found to be compliance with WHO standards, suggesting that vetiver bioremediation sustainable environmentally friendly method presents viable option for treating Bangladesh.
