Resumo: The leachate is the result of the percolation of water rain and water that is released during decomposition of waste. The leachate is a effluent with a low degradability, composed by high organic matter concentrations, inorganic, recalcitrant substances, toxic metals and other products with high potential harmful. One of the emerging techniques of treatment is evaporation, which is the transformation of the leachate liquid fraction in gas and solid, whose operation is based, fundamentally, in the use of three climate parameters (wind, relative humidity and temperature). A pilot-field was build, composed by a number of tanks, sprinklers and a high evaporative specific area panel, where the leachate was sprayed. Have been identified possible emissions of volatile organic compounds from the leachate evaporation, and the microorganisms dispersal around the pilot. For the leachate treatment, the evaporator efficiency was evaluated in physical, chemical and biological terms. The probability of finding volatile organcic compound was higher in pilot field against the samples collected at 15 metres from the pilot. However, microorganisms dispersion around the pilot, occurs in a maximum of 7 to 8 meters. The evaporation phenomenon allowed an improvement in leachate quality in terms of toxicity, and other parameters
