Analysis of the physicochemical parameters of the water quality of stream Urumutum in the city of Tabatinga - AM

Abstract

Water is an essential resource for the maintenance of life that everyone and it is up to all human beings to preserve our water resources. This work aimed to evaluate the physical chemical parameters of the water of the Urumutum stream, which is located on the INCRA road, in the rural area of the municipality of Tabatinga-AM. For the analysis of water quality, two collections were carried out, in a period of one month. The parameters analyzed were: ammoniacal nitrogen, electrical conductivity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), dissolved iron, nitrite, nitrate, Ph, temperature and turbidity. The results obtained in the laboratory analyzes were compared with the water quality standards established by CONAMA 357/2005, in which some parameters outside the established standards were observed. Being them, the electrical conductivity, BOD, COD, temperature and dissolved oxygen, showing high degradation of the water course generated by the accumulation of residential waste that consequently alters the water quality of the stream. Based on the study, it was possible to conclude that the water quality of the Urumutum stream is in a critical state due to anthropic actions. Public policies must be taken immediately in view of the fact that the lack of sanitation, added to the abandonment of public power, can generally cause serious problems in the health of residents, leading to an increase in diseases caused by contamination of the stream water.
