ANÁLISE HIDROQUÍMICA DOS AQUÍFEROS GUARANI E SERRA GERAL NO MUNICÍPIO DE IBIPORÃ-PR

Abstract

The Serra Geral (SASG) and Guarani (SAG) aquifer systems are the most important aquifers in the state of Paraná, mainly due to their excellent chemical quality and production potential. This paper presents the analysis of two wells of the Guarani Aquifer System (SAG) and twenty-five wells of Serra Geral Aquifer System (SASG) located in the municipality of Ibiporã - PR, having as main objective the characterization of groundwater chemical parameters. Field work was carried out to survey the study area. The chemical parameters were analyzed: bicarbonate, carbonate, chloride, fluoride, nitrate, nitrite, and sulfate, and to analyze these parameters were used different methods as UV spectroscopy, turbidimetry and titration with silver nitrate. Piper diagram was developed in order to analyze possible connections between SAG and the SASG. Changes in the concentration of these parameters can cause harm to human health, since often the water from SGAS has a fluorine increase in its composition. As a result, anomalous fluorine patterns were identified in the SAG wells, but not exceeding the limits permitted by CONAMA RESOLUTION 396/2008 and 2914/2011 Ordinance of the Ministry of Health.
