The purpose of the research was to evaluate the degree of reduction of the bacterial load of water using as chemical disinfectant chloramine T 1% (ChT1%) and physical disinfection using UV at a wavelength of 253.93 μm, 30 minutes exposure time. The results of the research show a more significant reduction of TNG/ml of water in samples subjected to exposure to UV, but in this case the decrease is affected by the turbidity of the water.
