Saneamento básico: impactos ambientais causados pelo despejo de esgoto no rio negro (Amazonas - Brasil).63 Folhas. 2022. Dissertação do programa de pós-graduação em Engenharia, Gestão de Processos, Sistemas e Ambiental (EGPSA), Instituto de Tecnologia e Educação Galileo da Amazônia (ITEGAM), Manaus, 2022.https://rigalileo.itegam.org.br/handle/123456789/71Basic sanitation is a set of measures aimed at preserving or modifying environmental conditions in order to prevent diseases and promote health, improve the population's quality of life and individual productivity, and facilitate economic activities. Thus, the disorganized and inattentive growth of urban centers, added to the lack of public policies and targeted investments, cause irreparable damage to the environment as a whole and to the health of populations due to failures in the basic sanitation system. The objective of this work was to evaluate the impacts caused by the dumping of untreated effluents in the Rio Negro; to carry out microbiological analyzes of water samples from various points on the edge of Manaus, as well as streams (small tributaries of the Rio Negro), in order to assess the health of these water bodies, and the progress of their pollution today, comparing the results obtained within the limits permitted by current legislation; to analyze the possibility that there is the dumping of untreated wastewater directly into the Rio Negro, mainly the use of the subfluvial outfall, from the perspective of the aforementioned having a supposed capacity for self-purification. Another of the goals of this study is to propose the update of the Municipal Basic Sanitation Plan of the city of Manaus, mainly with regard to the establishment of a maximum period to reach a satisfactory percentage in the population's access to the collection and treatment of sewage in the municipal network. For that, water samples were collected from five points in the city and microbiological characterization analyzes were carried out. It was possible to infer from the results that the pollution in the creeks and edge of Manaus are evident, considering that in all five points evaluated the presence of microorganisms harmful to human health was found. It was noted that the Rio Negro, on the edge of Manaus, does not meet the standards of potability and quality of water for human consumption, largely due to the receipt of disorderly effluent discharge. For the above, the present dissertation is a way to alert public authorities, private institutions and also the population, that there is a need to accelerate the implementation of services related to basic sanitation in the city of Manaus, in order to avoid the irreversibility of damages. caused, as well as inform about the current conditions of our waters. Making it clear that the problem, still reversible, can become a natural disaster with serious socio-environmental impacts.pdf.Saneamento básicoImpacto ambientalLegislação ambientalRio negroAmazôniaDissertação3.07.00.00-0 Engenharia Sanitária
