Determination of Potential of Aquifer Contamination in the Municipality of Artur Nogueira (São Paulo, Brasil), Through Geoenvironmental Attributes ; Determinación del potencial de contaminación de acuíferos en el municipio de Artur Nogueira (São Paulo, Brasil), a través de atributos geoambientales ; Determinação do potencial de contaminação de aquíferos no município de Artur Nogueira (São Paulo, Brasil), por meio de atributos geoambientais

Human activities exert constant pressures on groundwater. In fact, one of the most relevant problems is the anthropogenic addition of contaminants and pollutants, closely related with the land use. Analyzing the response of geoenvironmental factors associated to land use and occupation is an essential tool to identify how prone to contamination an aquifer is it, also widely used for territorial planning. Thus, the present study aimed to determine the aquifer contamination potential in Artur Nogueira city (São Paulo, Brasil). To do so, we used study area attributes related to the geology and geomorphology (aquifer units, unconsolidated materials, and slope), including soil use and occupation features. By using multi-criteria analysis and map algebra, this region exhibited a huge range of contamination potential. Our results showed that approximately 47 % of the city area displayed a medium potential. The highest one covered approximately 24 % of the study site. The large agricultural and livestock matrix in the region contributed strongly to those results. Another important factor was the physical environmental characteristics. This highlights how a planning lack regarding the land use and occupation directly influenced the groundwater contamination potential. ; Las actividades antrópicas ejercen presión sobre las aguas subterráneas, y son la inserción de contaminantes y sustancias nocivas en el medioambiente uno de los principales problemas relacionados con el uso de la tierra. Analizar la respuesta de los factores geoambientales al uso y la ocupación del suelo es fundamental para identificar regiones con mayor o menor potencial de contaminación de acuíferos. El propósito de este estudio es determinar el potencial de contaminación del acuífero en el municipio de Artur Nogueira, en São Paulo (Brasil). Se utilizaron atributos relacionados con la geología y la geomorfología (unidades acuíferas, materiales no consolidados y pendiente), junto con el uso de la tierra, que se clasificaron entre potencial de ...
