Qualidade Das Águas De Poços Rasos Em Área Com Déficit De Saneamento Básico Em Cuiabá, Mt: Avaliação Microbiológica, Físico-Química E Fatores De Risco À Saúde

Abstract

RESUMOAs doenças de veiculação hídrica são responsáveis por milhões de mortes todos os anos no mundo. Tais doenças estão relacionadas à falta de saneamento básico e água de qualidade para consumo humano. Em Cuiabá, MT, o bairro Pedra 90 apresenta problemas relacionados à falta de água em condições adequadas de quantidade e qualidade, o que levou a população a construir poços rasos em suas residências para garantir um abastecimento alternativo. Este trabalho avaliou a qualidade das águas de dezessete desses poços e identificou que os mesmos apresentam contaminação por Escherichia coli e bactérias heterotróficas, provavelmente por estarem próximos às fossas rudimentares que são comuns na região. O consumo dessas águas representa risco à saúde da população. PALAVRAS-CHAVE: WATER QUALITY OF SHALLOW WELLS IN AREA WITH LACK SANITATION IN CUIABÁ, MT: MICROBIOLOGICAL AND PHYSICAL-CHEMICAL EVALUATION AND HEALTHY RISKS FACTORS ABSTRACTWaterborne illnesses are responsible for millions of deaths every year in the world. These illnesses are related to lack sanitation and unsafe water for human consumption. In Cuiabá, MT, the Pedra 90 Neighborhood has problems related to quality and quantity of water which led people to build shallow wells in their residences to ensure an alternative supply. This study evaluated the water quality of seventeen of these wells and found that they are contaminated by Escherichia coli and heterotrofic bacteria. The proximity of the wells to rudimentary tanks, that are common in the region, can explain this microbiological contamination. The consumption of this unsafe water can be harmful to population health.

Water and health risk assessment in the Aracaju Expansion Zone - SE

“…The results of this research corroborate those obtained by other authors such as Brun et al (2016); Santos et al (2015); Capp et al (2012); Conicelli (2014) and Camargo (2009) who relate microbiological contamination to factors associated to the absence of sanitation in practices such as digging wells in areas where there are septic tanks nearby, or areas where solid waste is being discharged on the ground in the open air. That set of problems could be what is jeopardizing the water table during the rainy periods showing that even though microbiological contamination may occur in locations far apart, they are locations with similar characteristics.…”

Management of water resources in semi-arid: assessment of the drinking water supply in rural communities of Chapada do Apodi-RN

“…The pH values of the studied water samples presented an average of 5.92 (Table 3), and in the rural community of Paraíso, analysis 01, it could be observed value of 4.120 (row 132 and Column 03, These results showed similar quality to values obtained by Medeiros, Lima, and Guimarães (2016) from groundwater source waters in municipalities of Pará state, the samples revealed acid values that do not match the recommended values for human consumption; by Brum et al (2016), which ranged values between 4.46 to 6.96, in shallow wells from an area with lack of basic sanitation in Cuiabá/MT; and by Araújo et al (2011) who obtained data of 4.25 and 4.46, from a residential water tank and from one of the springs that supply the rural communities in the state of São Paulo. Therefore, it is observed a tendency for waters in rural areas to have acidic quality.…”

“…In the study carried out by Pinto Filho et al (2018), residents from rural communities of CPCA/RN mentioned health problems associated with water quality, including diarrhea (10.5%), and dengue (3.4%). Taking these figures into account, it can be assumed the evident connection between water quality and the emergence of water-borne diseases (BRUM et al, 2016;SOARES et al, 2018). Thus, to associate health and environmental quality, it is necessary to analyze the water condition for human consumption in the rural communities studied.…”

“…In Brazil, several studies on water supply have been developed, especially: Amaral et al (2003), Araújo et al (2011), Bortoli et al (2018), Brum et al (2016), Cavalcante (2014), Giatti (2007), Lemos (2003), Medeiros, Lima e Guimarães (2016), Morais et al (2017), Pessôa (2013), Pinto Filho et al (2018), Quesado Júnior et al (2008, Soares et al (2018) e Souza et al (2016). However, similar studies have not yet been conducted in Chapada do Apodi/RN, being important for providing data on local environmental sanitation, which will allow to inhibit, or prevent the occurrence of diseases.…”
