Survey of the physical-chemical and microbiological quality of water

Understanding the importance of water for human consumption, and the problems related to the contamination that humans cause in them and ends up harming it, this study aims to analyze the physico-chemical and microbiological parameters of the water of three points of supply in the municipality of Anagé in Lindo Horizonte Bahia, comparing with the norms of quality of the 518 portaria of the ministry of health. Without proper treatment and proper care, water becomes a vehicle for disease-causing microorganisms. For the accomplishment of this work three samples were collected, being of the truck kite that and supplies the town, of the rain collected in an appropriate reservoir and of the local dam. The analysis was made with the following physical-chemical parameters: Electrical conductivity, turbidity, hydrogen ionic potential, electrical resistivity, chlorine content determination, total alkalinity, total hardness and dissolved solids content. For the microbiological analysis, the total and fecal coliforms were tested according to the methodology (SMEWW-SM9223). According to the analyzes carried out, the water from the dam is not suitable for human consumption in accordance with current legislation, due to the high turbidity content and the presence of Escherichia coli. The analyzes of the other supply points are also not in adequate drinking conditions according to the parameters required by the legislation. New analyzes can be carried out to reinforce the results obtained and the population should be made aware of the quality of the water being consumed and the importance of the same for the human being.
