Avaliação de vulnerabilidade à contaminação das águas subterrâneas do município de Claro dos Poções - MG

Abstract

In the last years, the use of water resources has become the subject of many debates. The rapid development of urban, agricultural, industrial and mining sectors has created an imbalance between the supply and demand of water around the world. For this reason, several studies have raised the need for projects, alternatives and practices for the reuse of natural ecosystems. From all potable water available on the planet, the majority is found in the underground layer, housed in aquifers. These groundwaters are a natural resource that is often neglected and needs a careful look, as it may be susceptible to vulnerability and contamination by several factors. Thus, this study aims to assess the vulnerability of groundwater to contamination in the municipality of Claro dos Poções - MG. To this end, the GOD methodology was applied (G = Groundwater occurrence or aquifer type, O = Overall lithology of aquifer and, D = Depth of groundwater). After the collection and treatment of data referring to groundwater in the region, they were interpolated using the QGis software (3.16.5) to generate a vulnerability map that reflected the situation of the studied area. Based on the results of the analysis, four classes of vulnerability were indicated, namely: low, medium, high and extreme. The analysis results can be used for recommendations for the management of aquifer waters in the study area.
