During the summer in 2010, Brazilian communication media (CM) reported the case of landslides which resulted in 267 victims, among which 45 died in Morro do Bumba, Niterói / RJ. Subsequent studies revealed that the phenomenon was due to a combination of factors such as the topographic features, the presence of methane gas, the excessive trash and intense summer rainfall. Similar situations are common in tropical countries such as Brazil. In this research, we highlight the Metropolitan Region of São Paulo (MRSP) where the population of Sitio Joaninha lives. It is located between the municipalities of Diadema and São Bernardo do Campo, this last one housed from 1970 to 2001, an old landfill called Alvarenga, whose environmental liabilities were materialized in Antropossolos Líxicos, on which there are housing nowadays. According to some residents the physical conditions of the land added to the instability of the soil class, landslides have already occurred and spontaneous combustion. In this context, this study aimed to evaluate the social and environmental quality of the study area, directly related to the presence of Antropossolos. To this end, we applied 75 questionnaires with qualitative questions. With an auger of a Dutch design were collected about 2,000 cm3 of land, with 1 meter depth in 5 collection points of a hill in Sítio Joaninha. At the samples collected were identified anthropogenic materials such as glass, plastic, fabric, among others. In Soil Mechanics Laboratory of UNESP/FEA Campus of Bauru, the following characterization tests were conducted: granularity, Atterberg limits or levels of consistency and density of solids (ABNT, 1984)...
