Análise da qualidade de água subterrânea com enfoque nas diferenças socioeconômicas das regiões do Lago Sul e de São Sebastião

Abstract

The groundwater has been one of the main sources of water supply in Distrito Federal which has low drainage densities, such as rivers and brooks. However, the disordered occupation and socioeconomic contrasts between the areas may influence the aquiferous’ water quality. Far from 17 km, São Sebastião and Lago Sul are examples of these differences. 41,1% of the population in the first city presents a level of education equivalent to junior high school and have a per capita income lower than R$ 1.500,00. Meanwhile, it was observed that 41,5% of the population in the second city presents a high level of education and a per capita income higher than R$ 11.000,00. The aim of this essay is to verify if these dissenting social differences, such as the increasing urban occupation, influence the groundwater quality of the regions studied, besides analyzing whether activities like the pouring out of effluents on superficial fountainheads alter the aquiferous’ situation.
