Abstract: The objective of this work was to analyze the water of the Rio Preto, in the municipality of Unaí/MG, using the methylene blue (AM) technique in comparison with usual methods. For each collection point, a methodology was adopted based on the analysis of water quality with the AM technique in comparison with usual methods: temperature, pH, dissolved oxygen and electrical conductivity. The AM technique reports that the anaerobic decomposition of organic matter is carried out through reduction processes. From the analyzes carried out with AM, the relationship between the degree and time of water discoloration was observed, which represents the water contamination index. The color of the samples remained unchanged after 120 hours of observation, indicating that the samples are suitable for use.
