Identificação Preliminar de Áreas Suscetíveis à Vulnerabilidade Natural à Contaminação de Águas Subterrâneas: um Estudo de Caso na região dos bairros da Grande Tijuca localizado no município do Rio de Janeiro

Abstract

The present work approaches the perspective of the context of identification of points of vulnerability of groundwater in the face of the management of groundwater resources and the management of contaminated areas. Defending as a basis the presence of a normative system present in the state of Rio de Janeiro regarding situations involving the consumption of underground water, management of contaminated areas and, also, the issue of water quality security involving the consumption of groundwater resources and society. Still, there is a methodological approach to the GOD method and a low-cost application and, based on secondary and public data, as a way of preliminary identification of areas susceptible to vulnerability to groundwater contamination. The study region covered the area established by the administrative regions of Great Tijuca, partially located in the Rio do Mangue sub-basin region, and presented as a preliminary result that this area is located in a region of vulnerability with indexes ranging from medium to high. Thus, based on the methodology and application of the IDW (Inverse Distance Weighted), it was possible to elaborate a preliminary map of the distribution of the punctual results resulting from the natural vulnerability to groundwater in the area of interest. As a preliminary result, it can be seen that such a study may serve as a basis and subsidy for decision making for future more specific hydrogeological studies of regions of interest with a higher vulnerability index.
