In this paper, leachate treatment efficiency was evaluated on the basis of Leachate treatment value of leachate before and after treatment by using coagulation techniques passing through permeable ZEA MAYS powder (CORNCOB) in a laboratory scale study. Leachate treatment value can be used as a tool to assess the leachate pollutant potential of landfill sites particularly at places where there is a high risk of leachate migration and pollutant of groundwater and thus can help to take necessary decisions as deem fit. Permeable zea mays (CORNCOB) powder consisted of low cost locally available waste materials, which is an innovative technology to treat landfill leachate contamination. Leachate sample of vaniyambadi municipal solid waste landfill site of Vellore City, Tamilnadu (India) was collected and analyzed for 8 significant leachate pollutant variables viz pH, TDS, BOD5, COD, Chloride (Cl? ), phosphate, calcium and ammonia nitrogen to estimate its pollutant potential. The concentration of all the studied leachate pollutant variables exceeded the permissible limits. Vaniyambadi area has 19, 5061 population and total area is 9.54 km2. Therefore, all the leachate generated finds its path into the surrounding environment. Based on adsorption studies, maximum adsorption was observed at room temperature under acidic condition of pH 7.4. Based on the study, zea mays Powder is used as an effective Natural for reducing the leachate pollutant Concentration present in municipal solid waste.
