Resumo: Groundwater generally have better natural condition than surface water. However, because of lithological diversity, they present variable chemical composition, which can also be modified by contaminant loads. This study aimed to evaluate the hydrochemistry, the natural vulnerability of aquifers to contamination and the potentiometric surface of the Serra Geral Aquifer in the municipality of Ametista do Sul, RS. The data was obtained from the Groundwater Information System. There was selected eleven captures information with electrical conductivity, pH, sodium, potassium, calcium, magnesium, chloride, carbonate, bicarbonate, sulfate, fluoride, total alkalinity, static level profiles geological and geographical coordinates. From the Qualigraf 1.1 program, there were generated Piper diagrams for chemical classification and diagrams Stiff and Schoeller-Berkaloff to check the tendency of water. The vulnerability was determined from the GOD system. The pH was between 7.4 and 10.2. As for the chemical classification, ten samples showed up with sodium bicarbonate and sodium as mixed. Five samples showed fluoride concentrations greater than the Maximum Allowed 1.5 mg L-1 established by the Ministry of Health and the natural vulnerability of the aquifer to contamination ranged from insignificant to low.

Entretanto, pela diversidade litológica, apresentam variável composição química, que também pode ser modificada por cargas contaminantes. Assim, este trabalho objetivou avaliar a hidroquímica, a vulnerabilidade natural do aquífero à contaminação e a superfície potenciométrica do Aquífero Serra Geral no município de Ametista do Sul, RS. Os dados foram obtidos do Sistema de Informações de Águas Subterrâneas. Foram selecionadas onze captações com informações de condutividade elétrica, pH, sódio, potássio, cálcio, magnésio, cloreto, carbonato, bicarbonato, sulfato, flúor, alcalinidade total, nível estático, perfis geológicos e coordenadas geográficas. A partir do programa Qualigraf 1.1 foram gerados os diagramas de Piper para a classificação química e os diagramas de Stiff e de Schoeller-Berkaloff para verificar a tendência das águas. A vulnerabilidade foi determinada a partir do sistema GOD. O pH esteve entre 7,4 e 10,2. Quanto à classificação química, dez amostras mostraram-se bicarbonatadas sódicas e uma como sódica mista. Cinco amostras apresentaram concentrações de fluoreto maior que o Valor Máximo Permitido de 1,5 mg.L-1 estabelecido pelo Ministério da Saúde e a vulnerabilidade natural do aquífero à contaminação variou de insignificante a baixa.Universidade Federal de Santa Maria2015-12-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://periodicos.ufsm.br/remoa/article/view/2003310.5902/2236130820033Monografias Ambientais; REMOA, V. 15, N. 1, JAN.-APR., 2016; 94-104Revista Monografias Ambientais; REMOA, V. 15, N. 1, JAN.-ABR., 2016; 94-1042236-13082236-1308reponame:Revista Monografias Ambientaisinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttp://periodicos.ufsm.br/remoa/article/view/20033/pdfCopyright (c) 2016 Revista Monografias Ambientaisinfo:eu-repo/semantics/openAccessTerra, Lueni GonçalvesBorba, Willian Fernando deFernandes, Gabriel D'AvilaTrombeta, Helena WichineskiSilva, José Luiz Silvério da2021-05-07T12:42:37Zoai:ojs.pkp.sfu.ca:article/20033Revistahttps://periodicos.ufsm.br/remoaONGhttp://cascavel.ufsm.br/revistas/ojs-2.2.2/index.php/remoa/oai||remoa.ufsm@gmail.com2236-13082236-1308opendoar:2021-05-07T12:42:37Revista Monografias Ambientais - Universidade Federal de Santa Maria (UFSM)false
