ANÁLISE DOS PARÂMETROS FÍSICO-QUÍMICOS DA ÁGUA DO RIO VERDE, GOIÁS

Abstract

Water is a vital element for the maintenance of terrestrial life. The water used for human consumption must be of high quality, and must be within potability standards, a condition that guarantees safety when consumed. There are many characteristics that can make water unfit for consumption, whether of physical or chemical origin. The city of Carmo do Rio Verde and the Instituto Federal Goiano – Campus Ceres have the Verde River as their main source of water, which runs through agricultural regions for cultivation, cattle raising and sugarcane monoculture. The present study aimed to analyze the physicochemical quality of the water of the Verde River. Water samples were collected during the rainy season at strategic points in the year 2020. The results indicated that the following parameters analyzed pH, alkalinity, water hardness, OD, temperature and free CO2 were within the standard values for class II fresh waters by CONAMA. The parameters turbidity, water transparency and chloride concentration were altered, which is probably due to the rainy season as they were collected. Considering the great importance of the Verde River that provides water to the municipalities of Ceres and Carmo do Rio Verde, analyzes of the physicochemical quality of the water are of great relevance for the region.
