With the advent of the industrial revolution, the use of disposable materials has become a common practice in society, resulting in the increased production of solid waste in urban areas, and the peculiarity of its features: of organic materials to heavy metal. The solid waste produced in Ourinhos / SP is allocated to the controlled landfill, giving rise to specific pedogenetic volumes, the Antropossolos Líxicos. Such development represents a potencial souce of contamination of soil and water. This way, this research aimed at identifying a possible contamination by Total Chromium in the soils downstream of the controlled landfill of Ourinhos/SP, and analyzing physically and chemically eight soil samples at depths of 0-20 and 20-100 cm. In the context of saturation of the landfill, the Selective Collection, held by the Cooperative Recicla Ourinhos, also becomes the object of this study, considering the 'catador' of recyclable materials as an actor of the waste management. The study showed that the presence of chromium in the samples does not denote contamination but infers physicochemical changes in the soil. Within the urban solid wast, the Recicla Ourinhos changes in the soil. Within the urban solid wast, the Recicla Ourinhos becomes a service that provides the Selective Collection, reinserting on average 200 tonnes of waste collected in the city, to the chain of materials.
