Potencial de Contaminação de Aquíferos por Atividades Antrópicas da Bacia do Ribeirão do Meio - Município de Leme - SP

Abstract: A compreensão do processo de expansão das atividades antrópicas, em bacias hidrográficas, se mostra fundamental nos dias atuais. No que tange ao problema da contaminação das águas subterrâneas, a análise do uso e cobertura do solo existente e das variáveis do meio físico podem auxiliar na compreensão e gestão desta problemática. O presente trabalho teve por objetivo elaborar a carta de potencial de contaminação de aquíferos por atividades humanas na bacia hidrográfica do Ribeirão do Meio (Leme, SP), abrangendo… Show more

“…The MCA was based on the methodology described by Costa et al (2015a), which is the integration of information plans in a GIS environment by means of decision matrices using the Weighted Sum tool ArcGIS 10.2 software (ESRI, 2013). The cross-referencing of the geoenvironmental attributes were carried out two by two where values were attributed to the intersection of classes, and the weights, with values ranging from 1 to 5 (Very Low to Very High), were determined from the experience and expertise of the authors.…”

“…In the step 4, intending to consider possible groundwater contamination sources in addiction to natural environment data, and to complement the methodology proposed by Costa et al (2015a); information related to sanitary sewage, water supply, solid waste and the location of contamination sources in Araras (IBGE, 2010) were included in this analysis (CETESB, 2014), as well as the layout and water level depth of the deep wells in operation in ARW (CPRM, 2015).…”

“…A identificação do potencial de contaminação da bacia hidrográfica do Córrego do Gouveia consistiu na análise da relação entre os condicionantes do meio físico com o padrão de ocupação exercido pelas atividades antrópicas no local, assim como propõem Tavanti et al (2009) e Costa et al (2015.…”

“…Para os atributos relacionados à Geologia e Pedologia, o critério para a atribuição de valores foi que quanto mais arenoso o material, mais grosseiros seriam os grãos e consequentemente seria maior potencial de infiltração e contaminação. Sendo assim, os materiais mais arenosos receberam valor 5 e os mais argilosos, valor 1 (Costa et al, 2015).…”
