Waste incineration (tyres, used oil and treated wood) in kilns and bathhouses is a major source of air pollution. A large portion of the waste is still disposed of in illegal dumpsites, often in or along stream or river beds and areas where water resources are vulnerable, which causes water pollution. However, no studies have been undertaken to identify possible impacts from the leaks of uncontrolled landfills to groundwater and surface water, and there is no basic frame of reference for setting the objectives that need to be achieved, the thresholds that should not be exceeded and the corrective measures that must be applied. Liquid waste from handicraft activities and most industrial activities are discharged directly into surface water. Groundwater is also affected by the pollutants present in the soil.
