标题：USO DA ANÁLISE MULTIVARIADA COMO SUPORTE ESTATÍSTICO NA AVALIAÇÃO MACROSCÓPICA DOS IMPACTOS AMBIENTAIS EM NASCENTES NA LOCALIDADE DE CARNE DE VACA, PERNAMBUCO
摘要：Normally, the relationship between human beings and the environment, particularly water resources, is not always harmonious and conscious. In this context, the present study aims to analyze the macroscopic environmental impacts observed in three springs located in an urban area in the village of Carne de Vaca, Pernambuco, as well as to investigate whether there are changes in the environmental quality of the springs. Through the Environmental Impact Index on Springs and the application of the analysis of main components, it was possible to distinguish the environmental quality between the springs, as well as the main environmental impacts acting on this ecosystem. Thus, the springs show signs ofenvironmental degradation, mainly due to irregular dumping of solid waste, use by humans and cemeteries built close to the springs. Through the analysis of main components, two groups with distinct environmental impacts were recognized, group 1 consistingof spring 3 presents lesser impacts and greater environmental conservation, however, group 2 formed by springs 2 and 3 indicate regions impacted by human activities. In this context, inspection and environmental education activities are suggested to raisethe awareness of the people who use these springs, in addition to analyzing the quality of this water to verify that it is properly within the limits established by Brazilian legislation.
