Abstract

O presente trabalho aborda as características naturais das águas subterrâneas do município de Restinga Seca, situado na borda da Bacia do Paraná, sul do Brasil, na Depressão Central constituída predominantemente por arenitos pertencentes à Zona de Afloramento (ZA) do Sistema Aquífero Guarani - SAG. O município possui 54 captações por poços cadastrados no Sistema de Informações de Águas Subterrâneas/SIAGAS, sendo 19 selecionados no estudo. Dentre as principais fontes potenciais de contaminação foram identificados 3 postos de combustíveis e 2 cemitérios. O estudo apontou um índice de vulnerabilidade dos Sistemas Aquíferos (Serra Geral e Guarani) para todo o município: 0,02% média; 48,98% baixa e predominando a insignificante com 51,00%. O Perímetro urbano apresentou cerca de 23,00% na classe média e 67,00% na insignificante. Observou-se que os pontos potenciais de contaminação estão localizados em áreas das classes de vulnerabilidade insignificante e baixa.

This paper addresses the natural characteristics of groundwater in the municipality of Restinga Seca, situated on the edge of the Paraná Basin in the Central Depression, southern Brazil. It consists predominantly of sandstones belonging to Outcrop Zones (ZA) Guarani Aquifer System - GAS. The city has 54 registered wells funding 19 were selected to this study. Were identified the main potential contamination sources three gas stations and two cemeteries. The study reported a vulnerability index Aquifers Systems (Serra Geral and Guarani) for the entire county: 0.02% moderate, 48.98% low and predominantly negligible with 51.00%. The urban perimeter showed about 23.00% moderate and circa 67.00% in negligible class. It was observed that the points of potential contamination areas are located in classes of low and negligible vulnerability.

Keywords: Aquifers, GAS, contamination, cartograms.
