Most rural areas in Brazil do not receive treated water, and the population of these areas uses springs or wells for their daily consumption without control potability. Thus, the water becomes a vector of transmission of diseases, caused mostly by enteric pathogens origin. Therefore, the aim of this study was to verify the microbiological quality of water from two springs in the rural municipality of Varre-Sai, RJ. Samples were collected for seven months, and analyzed by the Multiple Tube Method for detection of total and thermotolerant coliforms. Contamination was found in four samples of point 01, maximum 1600 NMP/100mL, while the point 02 showed contamination in only two samples with a maximum of 23 NMP/100mL. The presence of protective structures in point 02 and their absence in point 01 may have contributed to these differences. The construction of structures protect of the springs associated with the preservation of natural vegetation can positively influence water quality.
