Physico-chemical characteristics of leachate from a common hazardous waste disposal facility in South India
Variations in the characteristics of leachate from the landfill of a Common Hazardous Waste Treatment Storage Disposal Facility (CHWTSDF) in South India was analysed in terms of pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), COD, calcium, magnesium, sodium, potassium, total alkalinity, chlorides, sulphates and selected heavy metals (Pb, Cd, Cr
+6, Zn and Ni). The leachate characteristics were compared with the quantity of hazardous waste disposed in landfill and rainfall. Field data on the leachate generation were compared to the same predicted using Hydrologic Evaluation of Landfill Performance (HELP) model.
