Problems involving open-air urban solid waste (MSW) deposits have always been present in our country. In Rolim de Moura, the MSW deposit has been closed since 2015, requiring some steps to develop an efficient environmental rehabilitation methodology. The objectives of this study were to elaborate the main stages of a Degraded Areas Recovery Project (PRAD); evaluate the physical-chemical characteristics of the water and soil chemistry of the site; survey the history of the use of the area and propose measures to mitigate the liability in question. The methodology consisted of regulations, works already developed in relation to this theme, bibliographic reviews, interviews and collection and analysis of physical-chemical attributes of water and chemical parameters of the soil. Regional and local characterization regarding climate, geology, hydrology and vegetation was carried out. All parameters evaluated in the physical-chemical characterization of water were within the ranges established by CONAMA resolution 357/2005 for reuse water. As for the chemical characteristics of the soil, good fertility attributes were found, with the site being suitable for revegetation. For the proposal of environmental adaptation and recovery with forest species, the area was divided into three sectors, according to the gradient of resilience and proximity to adjacent forest fragments, proposing different recovery methodologies in each area. As a result of the research, a document was obtained that presents the main activities to be developed in the area of the former MSW deposit, so that problems arising from the deposition of waste are corrected, in order to stop the environmental damage.
