Este trabalho objetivou analisar a qualidade da água consumida pela comunidade universitária do Setor Profissional da Cidade Universitária Prof. José da Silveira Netto-UFPA. A metodologia empregada foi baseada em estudo quanti-qualitativo e em pesquisa laboratorial, nas quais as amostras de água foram coletadas dos bebedouros da universidade no período de agosto a dezembro de 2019. As variáveis escolhidas para pesquisa foram: pH, turbidez, cor aparente, sólidos dissolvidos totais, cloro residual livre, dureza total, nitrogênio amoniacal, temperatura e coliformes totais. Os dados da pesquisa foram analisados mediante a estatística descritiva (média, máxima, mínima, coeficiente de variação e desvio padrão). Os resultados obtidos revelaram que nem todas as amostras estiveram dentro do padrão estabelecido pela Portaria de n° 888 de 2021, do Ministério da Saúde (MS), uma vez que os parâmetros de cor aparente e cloro residual livre apresentaram-se fora do recomendado. Além disso, constatou-se a presença de contaminação por agentes microbiológicos em alguns pontos monitorados. Logo, são necessárias intervenções para o melhoramento da qualidade da água na universidade, visando à segurança sanitária dos usuários.

Based on the norms and concepts to obtain the best quality water for the population's supply and consumption, this research aimed to evaluate the physicochemical parameters of the water quality of the Health Campus of the University City José da Silveira Netto, at the Federal University. Pará (UFPA) in Belém do Pará. Water quality assessment was performed on a regular basis every third Thursday of each month in order to obtain more accurate results on the water supplying the campus using data from the UFPA Water Treatment Plant (ETA) as a comparison. The parameters evaluated were apparent color, turbidity, electrical conductivity, temperature and pH. A relationship was established between the distance of the sample points and the ETA, and correlated with the temporal variations. All points showed high values for the variables apparent color, turbidity and conductivity and, in general, all points had the same behavior over the months, with similar variations. Moreover, the distances of the sampled points and the WTP do not justify the high concentration of the variables. The importance of an evaluation of the chemical quality parameters of this water is stressed.

This article aims to analyze and characterize the problem of anthropic interventions along the Tucunduba stream, located in the city of Belém-PA, aiming to show how the process of urban expansion interferes with the water body, as well as the consequence of the disordered occupation in the margins of the igarapé. Since it causes soil changes and increased runoff, which is responsible for transporting organic and inorganic materials to the river, it significantly increases its pollutant load, causing flooding, river eutrophication, and other problems of water degradation. The bibliographic review and the on-site visit, as well as photographic record and georeferenced images made available in Google Earth, were used for the basement of the same, observing the general condition of the area, to characterize the anthropic factors that contribute to the degradation of the Igarapé.
