    Brazil is a country with great potential for water resources, but it does not mean that the water from their fountains have the necessary quality for human consumption.

However, the addition of chemicals to the water causes some suspicion among consumers, especially regarding the possible side effects of this practice. In this sense, the present research brings a methodological approach that has the general objective to verify the actual need for application of chemicals in the public water supply in the county of Morrinhos, Goiás State, indicating the viability or not of water consumption in natura by population. For this purpose, were realized collections and analysis of samples of gross water and treated following the standards required by brazilian law and international standards, plus access to results obtained by the Sanitation Company in the county between July / 2014 and December / 2015.
