| Abstract: | The leachate and groundwater samples were collected from the 2 km radius of Ghazipur landfill site. The high levels of EC, TDS, Chloride, Nitrate, Sodium, Potassium, BOD, and COD were observed in the leachate and groundwater samples. In leachate, metal concentrations were found in the order as – Fe > Zn > Cu > Pb > Ni > Cr > Cd. In groundwater, Zn, Ni, and Cu ranged as 0–0.386 mg/l, 0–0.013 mg/l, and 0–0.027 mg/l, respectively whereas Cd, Cr, and Pb were found in trace amount. The study clearly indicates that the percolation of leachate from the landfill site results in the contamination of groundwater of the surrounding area. |
