“…For the reasons presented and with the perspective of contributing to overcome the challenges of VIGIAGUA and improve the Program, this paper proposes a hazard assessment and categorization of microbiological risks associated with a water supply system, located in a mining municipality with less than 10.000 inhabitants, assigned to the Regional Health Management of Itabira (an agency linked to the State Health Department of Minas Gerais, Brazil), using the model suggested by Carmo et al (2008).…”

Consumption of non-potable water is a relevant public health problem due to the possibility of transporting numerous chemical and microbiological contaminants. In 2005, the Brazilian Ministry of Health created the National Program of Surveillance in Environmental Health related to the Quality of Water for Human Consumption (VIGIAGUA), with the primary purpose of managing risks related to water supply to human populations in Brazilian territory. However, VIGIAGUA does not have a methodology capable of characterizing or managing risks. The objective of this research is to create a working model to transform raw data into conceptual data related to low-, medium- and high-risk levels. The data used in the application of the model were obtained through the analyses of water-quality surveillance conducted by the Regional Health Management of Itabira, a municipality with less than 10 thousand inhabitants, whose history of water contamination is alarming. Twelve samples/month were collected between May 2017 and April 2018. The results of the treated water analyses were classified according to the presence of hazards and categorized into risk levels. The results showed 83.3% contamination by total coliforms at the treatment plant and 91.6% in the distribution system. The Escherichia coli contamination was 16.7% in the treatment plant samples and 45.2% in the distribution system. The system was categorized as "High Risk". The analysis of untreated water samples was carried out for the purpose of knowing the contamination pattern of the raw water of the region, finding 100% contamination by total coliforms and 97.2% contamination by E. coli.

“…While it is the right of every human being to have access to safe housing and basic services, many remote communities do not have, at least, a water supply system, which causes various health and social problems, such as increased incidence of water-related diseases (CARMO, BEVILACQUA;BASTOS, 2008), increased infant mortality and diseases caused by lack of hygiene, among others. In addition, these communities suffer from lack of information on basic concepts of sanitation, which makes them susceptible to diseases (SOARES; BERNARDES; CORDEIRO NETTO, 2002) and, more seriously, to death.…”

RESUMO Objetivou-se neste trabalho analisar a qualidade da água consumida pelos moradores das comunidades Morro Redondo e Baixios do assentamento quilombola da localidade Vão Grande, Município de Barra do Bugres, Mato Grosso, e os potenciais riscos à saúde da população. Avaliou-se alcalinidade, dureza, turbidez, condutividade elétrica, demanda química de oxigênio, pH, temperatura, cloretos, cálcio, magnésio, sódio, ferro e potássio, em diferentes fontes superficiais de abastecimento de água, e comparou-se os resultados com parâmetros que definem a potabilidade da água. As coletas foram realizadas no período de julho de 2013 a abril de 2014, sempre próximas ao dia 15 de cada mês. As variáveis alcalinidade e pH apresentaram valores mínimos abaixo do esperado e as variáveis turbidez e condutividade elétrica apresentaram valores máximos acima do permitido. De modo geral, as fontes de água avaliadas apresentaram boa qualidade, não oferecendo risco potencial à saúde dos moradores. Porém, para um consumo seguro, recomenda-se pelo menos filtração e desinfecção.

“…The term surveillance presupposes frequent and continuous evaluation of several factors in order to identifying potential human health risks and guide intervention and control actions, assuming thus a routine and preventive character 5 . Therefore, the drinking water quality surveillance process is presupposed by the performance of actions within three domains: 1) the identification and registration of the sources of water supply 2) the surveillance of the water supply authorities' performance and 3) the surveillance of the water quality performed by the health sector.…”

Surveillance of the drinking water quality din the Legal Amazon: analysis of vulnerable areas

et al. 2016

View full text Add to dashboard Cite

Low quality drinking water has been directly correlated to the occurrence of waterborne illnesses in northern Brazil. To minimize health risks related to the water supply, the Ministry of Health has proposed the implementation of the National Program for the Surveillance of Drinking Water Quality (VIGIAGUA) in Brazilian municipalities. Focusing on the Legal Amazon region, the present study demonstrates a historical account of the percentage of municipalities included in the VIGIAGUA program in place, which in 2013 reached 45.1% of the region municipalities. This study also identifies vulnerable areas in terms of the water quality in the states of Amapá, Amazonas and Maranhão. With this analysis of the current status of the drinking water supply, this study intends to support and direct the strategic efforts of environmental health monitoring in the region.
