ÍNDICES DE QUALIDADE DA ÁGUA DOS RESERVATÓRIOS DE SERGIPE

The environmental situation in areas surrounding the reservoirs of Sergipe has been alarmingly undermined by population growth and an analysis to establish sustainable development is unquestionably necessary and urgent. In this context, the present work aims to evaluate the water quality of the main reservoirs of the State on the basis of physical, chemical and biological parameters that embody the formulation of Water Quality Indices (SEQI). Were used environmental data provided by the Laboratory of Environmental Analytical Chemistry UFS and applied the different correlations IQA proposed in the literature to classify reservoirs accordance with the environmental regulations for such. The results show that urban growth in the vicinity of reservoirs, especially in relation to animal husbandry and horticultural activities, is putting the tanks in conditions that preclude the use of water for human consumption and that a policy of sustainable environmental development should be predominantly consolidated. Index Terms - Environmental parameters, water quality, water reservoirs.
