Abstract
The study analyzed the quality of drinking water used in Brazilian urban slum residences according to the standards established in Brazilian regulations. Bacteriological (n=231) and physicochemical parameters (n=134) were analyzed, as the Standard Methods for the Examination of Water and Wastewater establishes. The results revealed that contaminants in the water consumed, for the most part, exceed the limits of drinking water quality standards, putting the population's health at risk and reinforcing the urgency of the need for public policies.
Highlights
In Brazil, according to the last Demographic Census of 2010 of the Brazilian Institute of Geography and Statistics (IBGE), 11,425,644 people, corresponding to 6% of the Brazilian population, live in one of the 6,329 identified slums
The city of Rio de Janeiro is one of the cities that has more people living in these areas, with 1,393,314 residents in 763 slums, constituting 22% of the city's total population (IBGE, 2010)
The objective of the study was to analyze the drinking water quality used in residences in urban slums of Rio de Janeiro, RJ, Brazil, according to the standards established in Brazilian regulations, and to use socio-environmental questions to produce indicators regarding exposure to health conditions in these slums
Summary
The city of Rio de Janeiro is one of the cities that has more people living in these areas, with 1,393,314 residents in 763 slums, constituting 22% of the city's total population (IBGE, 2010). In urban slums, urban infrastructure (water supply, sewage, solid waste collection and drainage) is more precarious, leaving the population more susceptible to social injustices. This demonstrates the inability of public officials to meet and supervise the provision of social demands for adequate housing and sanitation, as well as the proper implementation of urban public services (Lopes et al, 2011). Most waterborne diseases could be avoided with an adequate sewage system and adequate water supply in residences (Ignacio et al, 2017; Handam, 2016)
