ABSTRACT
Leachate, generated by water percolating through landfills, can be classified into the two broad categories: non-hazardous and hazardous leachates. Basically, hazardous leachate is generated from hazardous waste or co-disposal landfills, whereas non-hazardous leachate is generated from hazardous waste or co-disposal landfills, whereas non-hazardous leachate is defined as leachate from non-hazardous solid waste landfills. Because of the high concentrations of contaminants in leachate, leachate is generally treated before it can be discharged or disposed of. 1
