Problemas socioambientais: urbanização desordenada e consequências para a qualidade das águas subterrâneas de Poços localizados nas imediações do lixão de Cidade Nova em Natal/RN

Abstract

The uncontrolled growth of Natal occurred at the 1970s caused serious urban environmental problems. In this context, the establishment of the “Cidade Nova” trash dump has expanded social and environmental problems by the high emission of contaminant itens on the soil, resulting in contamination of the water table, which brought serious problems for the quality of the water supply. This research aims to relate the pollution caused by the deposition of solid waste in “Cidade Nova” trash dump for more than three decades and the precarious sanitation deployed in the districts of Felipe Camarão, Planalto and Guarapes, with the consequent contamination of the wells of respective districts for human consumption. For this purpose, the literature was researched to the discussion about the relationship between urbanization, environmental issues and contamination of groundwater. Furthermore, was made a research about the physical structure of the study area, even as about the laws on the subject. About the methodology, a massive fieldwork was done in the wells for the water supply P1 and P5 at the Felipe Camarão district, and P2 at Planalto, from May/2014 to May/2015. The survey results show that there are contamination of the water intended for human consumption in those districts, and that this stems from the improper disposal of solid waste in the soil, beyond the absence of adequate sanitation, concluding that there are a latent need for public policies that mitigate such problems in the socio-environmental context of this area of study.
