The potability of water for human consumption influences the health and quality of life of populations. The springs represent the main source of supply for the families of the Florestan Fernandes Settlement (AFF), located in the south of the state of Espírito Santo. However, the suppression of native forests the AFF and the lack of recommended protection endanger the conservation and perenniality of springs, and may compromise water potability. The objective of this study was to evaluate the water quality of springs with different environmental characteristics in AFF. Eight springs were selected and periodic collections were performed and laboratory analyzes to evaluate the physical, chemical and microbiological parameters of the water. In addition, the Spring Environmental Impact Index (IIAN) was calculated to identify the degree of environmental impact on the contribution area of each spring. The results of water quality parameters, showed that there is non-conformity with the consolidation ordinance  nº 5/17 of the Ministry of Health and CONAMA Resolution 357/05. The IIAN showed that 25% of the springs were classified as "good", 37.5% as "reasonable”, another 25% classified as" bad" and 12.5% as "terrible". It was concluded that the use and occupation of the soil.
