DETERMINATION OF THE PHYSICOCHEMICAL PARAMETERS OF THE WATER OF THE JEQUITINHONHA RIVER IN THE CITY OF ALMENARA-MG

Abstract

Water quality is directly linked to the mode of land use and occupation, climate, topography, geology, vegetation cover and constituents of a hydrographic basin, i.e. water quality is related to both natural and anthropic aspects. Considering the importance of this natural resource for human consumption and possible problems that may cause, in the present work we analyzed the water supply of the Jequitinhonha River that passes through the municipality of Almenara - MG, the objective of analyzing physical and chemical parameters, such as Temperature, Conductivity, Alkalinity, Hardness, Chlorides, Iron Ions and Turbidity of the collected points. The collections were carried out in the rainy season of the region, in February 2020, in two points that pass through the city and is frequented by the population. The methodology used for both collection and analysis was established by the National Guide for sample collection and preservation (CETESB, 2011). According to the analyses performed, the values of Turbidity, pH, Alkalinity, Chlorides, Iron Ions and Hardness are within the parameters established by resolution no. 357 of CONAMA and also by Ordinance No. 518 of the Ministry of Health.
