Zoneamento Geoambiental para o uso sustentável de aquíferos no município de Pirassununga-SP (Geoenvironmental Zoning for sustainable use of aquifers in the municipality Pirassununga-SP)

Abstract

O avanço das atividades antrópicas no processo de ocupação do ambiente físico desencadeia impactos negativos na qualidade e disponibilidade de recursos naturais. Entre os recursos impactados estão os depósitos de águas subterrâneas que apresentam suscetibilidade a diferentes fontes de contaminação, natural ou antrópica, de acordo com características do meio, que apresenta capacidade de potencializar ou reduzir esse processo. Dentre as atividades com maior potencial a contaminação das unidades aquíferas está o cultivo de monocultura de cana-de-açúcar e áreas agrícolas com solo exposto, ambas identificadas no município de Pirassununga-SP. Neste sentido o objetivo do presente trabalho foi elaborar uma proposta preliminar de Zoneamento Geoambiental que visa o uso sustentável dos aquíferos em Pirassununga-SP, de modo a conservar a qualidade e disponibilidade das águas subterrâneas. Com base na análise do meio físico e antrópico da área e estudo, foi possível obter a caracterização geoambiental e interpretar as potencialidades à contaminação das unidades aquíferas presentes em Pirassununga-SP. Os resultados foram obtidos elaborando-se a cartografia geoambiental da área, e posterior aplicação das metodologias de Soma Ponderada e Lógica Fuzzy que relacionam os fatores geoambiental, no qual zonas com diferentes potenciais à contaminação foram geradas. Em sua maioria a área urbana, localizada na região central do município, demonstrou potencial baixo e médio a contaminação, enquanto zonas de alto e muito alto potencial encontram-se na área rural. A partir disso, o zoneamento demonstrou-se uma ferramenta potencial básica para o desenvolvimento de ações de gestores públicos, visando um planejamento territorial mais sustentável. A B S T R A C TThe advancement of anthropogenic Activities in the occupation process of the physical environment triggers negative impacts on the quality and availability of natural resources. Among the impacted resources are groundwater deposits that present susceptibility to different sources of contamination, natural or anthropic, according to characteristics of the physical environment, which present capacity to enhance or reduce this process. Among the activities with the greatest potential the contamination of the aquifers units are contamination of the aquifers units is the cultivation of sugar cane monoculture and agricultural areas with exposed soil, both identified in the municipality of Pirassununga-SP. Hence the objective of this work was to draw up a preliminary proposal of geoenvironmental zoning aimed at the sustainable use of aquifers in Pirassununga-SP, in order to preserve the quality and availability of groundwater. Through the analysis of the physical and anthropic environment of the municipality, it was possible to obtain the characterization of the study area and interpret as potentialities contamination of the units aquifers presents in Pirassununga-SP. The results were obtained from the drawing up the geoenvironmental cartography of the area, and subsequent application of the methodology of Weighted Sum and Fuzzy Logic that related the geoenvironmental factors, in which, areas with different potentials to the contamination generated. Mostly the urban area, located in the central region of the municipality demonstrated low and medium potential for contamination and, how much the high and very high potential areas are in the rural area. From this, the zoning demonstrated a basic potential tool for the development of actions of public managers, aiming at a more sustainable territorial planningKeywords: geoenvironmental cartography, contamination potential, gis, zoning.
