Water, fundamental for the maintenance of life, is a resource that goes through a constant crisis, especially regarding scarcity, mainly due to the increase in consumption and the uncontrolled pollution of water bodies. In addition to obtaining qualitative and quantitative information on water resources, the monitoring has the purpose of obtaining biological, chemical, physical and ecological information, as well as class classification. The sources of pollution in hydrographic basins are numerous, in this study the main focus found is urban pollution, which generates pollution mainly through the release of sanitary sewage 'in natura' and various solids, becoming sources of contamination quite aggravating when in the absence of riparian forests. In the present study, an analysis was carried out in which water quality was monitored at a point on Lake UHE Lajeado in the municipality of Porto Nacional/TO, its importance is due to the fact that the site serves as a new point of water capture for urban supply, it soon hopes to define whether the water body complies with the water quality standards - IQA NSF. Water quality was assessed by permissible limits established by CONAMA Resolution nº 357/2005 and NSF - National Sanitation Fundation, which was evaluated on 9 parameters that made it possible to calculate the IQA - Water Quality Index.
