Water Quality of the Meia Ponte River in the Catchment Region for Public Supply

Abstract

Purpose: This research aimed to evaluate the physical-chemical and microbiological quality of water in a certain region of the Meia Ponte river basin, through monitoring water quality parameters, and also to verify the interference of the rainy season in water treatment. Methods: Physicochemical and microbiological analyzes were carried out, evaluating the following parameters: pH, turbidity, color, temperature, total coliforms and Escherichia coli. The location chosen to carry out the collections was the water collection point for public supply from the Meia Ponte River. Results and conclusion: The physicochemical results obtained in this work were in accordance with CONAMA Resolution 357/2005 of the Ministry of the Environment; as for the microbiological results, which are based on CONAMA 374/2000, only the verified values for Escherichia coli are in accordance with the resolution. Research implications: The conservation of water sources is extremely important to ensure that the quality and quantity of treated water are in satisfactory condition to meet the population's demand. The quality of the water will depend on the activities that are carried out around the river basin. Originality/value: Verification of the interference of seasonality typical of the region, in the quality of water for public supply.
