Resumo: The compromise of surface water resources' quantity and quality, as well as the extensive use of groundwater, exposes aquifers to contamination risks. Considering this, combine natural and manmade influences is a proper strategy for potential aquifer contamination evaluation. This article presents charts of aquifer contamination potential in Rio Claro watershed (251,91km2, in Santa Rita do Passa Quatro, SP) at 1:50,000 scale, taking in account aquifer units, surface geology units, soil and steepness information; operated using multicriteria analysis. The classes “Very high” and “High potential” where the most representative classes of contamination potential in the watershed (performing 46.1% in 1994 and 48.6% in 2014). Obtained contamination potential expressed geological attributes influence in the area. Land use / land cover changes were determinant for higher potential maintenance with time. Adoption of land use / land cover control measures and improvements in tillage management are alternatives for the groundwater protection in this watershed.

Diante disso, combinar atributos naturais às influências antrópicas é uma estratégia adequada para a avaliação potencial de contaminação de aquíferos. O trabalho apresenta cartas de potencial de contaminação de aquíferos na bacia hidrográfica do Rio Claro (251,91km2, Santa Rita do Passa Quatro, SP) em escala 1:50.000, considerando as unidades aquíferas presentes, informações de geologia de superfície, materiais inconsolidados e declividade dos terrenos; combinados com uso e cobertura da terra, via análise multicritério em ambiente SIG. As classes de potencial “alto” e “muito alto” (46,1% em 1994 e 48,6% em 2014) foram as mais representativas na área. Os potenciais de contaminação obtidos expressaram claramente a importância dos atributos geológicos na área. As mudanças de uso e cobertura da terra identificadas no período foram determinantes para que o potencial de contaminação dos aquíferos aumentasse consideravelmente. A adoção de medidas de controle do uso/cobertura da terra e melhorias no manejo do solo são alternativas para a proteção das águas subterrâneas nesta bacia hidrográfica.Universidade Federal de Uberlândia2020-09-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/5622110.14393/SN-v32-2020-56221Sociedade & Natureza; Vol. 32 (2020); 657-673Sociedade & Natureza; v. 32 (2020); 657-6731982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/56221/29849https://seer.ufu.br/index.php/sociedadenatureza/article/view/56221/29850Copyright (c) 2020 Carlos Wilmer Costa, Reinaldo Lorandi, José Augusto Di Lollo, Vagner de Souza Serikawainfo:eu-repo/semantics/openAccessCosta, Carlos WilmerLorandi, Reinaldo Di Lollo, José Augusto Serikawa, Vagner de Souza 2021-07-01T16:18:20Zoai:ojs.www.seer.ufu.br:article/56221Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-07-01T16:18:20Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false
