Water is the source of life and an indispensable element of nature for human survival. Over the centuries, the available water resources have undergone constant crisis processes, especially when it comes to water pollution that affects its effectiveness for consumption. The monitoring of the water quality offers qualitative information about the water based on the parameters adopted in the CONAMA Resolution nº. 357/2005 and the calculation IQA NSF of the National Sanitation Foundation (APHA, 2005). The study about the water quality index aims to obtain information about the quality of the hydric resource available in Ribeirão São João in Porto Nacional - Tocantins, which has multiple uses such as: public supply, fishing, leisure, among others. The analysis undertaken to verify the quality of the water adopted procedures for analyzing the parameters of temperature, oxygen, pH, total nitrogen, total phosphorus, fecal coliforms, total solids and turbidity that occurred between the months of August and September 2021. The collection and analysis of water samples showed that the Ribeirão presents acceptable levels within the parameters established by the literature studied and infer that the water quality is considered average for the purposes of capitation and human consumption.References
