Abstract

Currently, we have been following the increase of reports in the media addressing problems of water scarcity, whether due to its quantity or the deterioration of its quality. Monitoring water quality is essential to ensure sustainable and safe use. In many places there is a lack of potable water to guarantee public supply and most Brazilian cities do not have an emergency plan for cases of extreme scarcity or contamination of the source that serves as the main water reservoir. This article conducts an epistemological study of the contribution of different areas of knowledge in order to assist in the production of learning and generate information that will help in decision-making regarding water management in small municipalities. Thus, the objective of this research was to carry out an inventory of spring waters in the urban perimeter of Caçapava do Sul/RS, mapping and verifying its quality. The research was developed with primary and secondary data. Secondary data were obtained through research in the existing bibliography and primary data were obtained through a technical visit, collection and analysis of water samples. At the end, with the analysis of the consolidated data, the sources were characterized in terms of water quality, informing about their classes of use through the analysis of the results in relation to Resolution No. 357 of the National Council for the Environment (CONAMA, 2005) and its potability, through Ordinance No. 2914 of the Ministry of Health (BRASIL, 2011) and the adapted Water Quality Index (WQI). Although the springs are apparently in a state of abandonment, most have water with physical-chemical characteristics within the standards, however, all the springs surveyed showed biological contamination and nitrates above the legal limit, probably related to lack of sanitation.
