“…Segundo Vasconcelos et al (2016), a construção apropriada para proteção de fontes hídricas melhora a qualidade de vida, prevenindo a contaminação de diversos patógenos, como é o caso da E. coli, especialmente quando não ocorre a desinfecção. Entretanto, é necessário que esse tipo de fonte de água seja periodicamente inspecionado para verificação da integridade das proteções existentes e que sejam realizadas manutenções, quando necessárias.…”

“…No Brasil, a água subterrânea é fonte de abastecimento em aproximadamente 39% dos municípios brasileiros, principalmente em assentamentos rurais onde é capitada através de poços ou cisternas (ANA, 2011;Santana, 2014). Porém, por vezes construídos sem critérios técnicos adequados, tornam suscetíveis à contaminação (Vasconcelos et al 2016). Importante ressaltar que a legislação não considera os poços amazonas como fonte de água potável, são tipos apenas como alternativa econômica encontrada por comunidades que não tem acesso a serviços governamentais de fornecimento de água potável.…”

O estudo trata da avaliação da qualidade da água de poços domésticos utilizados pelas comunidades rurais no arquipélago de Marajó- PA, a partir da análise dos parâmetros físico-químicos e microbiológicos. As amostras de água foram coletadas obedecendo as normas técnicas em vigor, ocorrendo no período de maior índice pluviométrico da região, com temperatura entre 23°C e 32 °C. Para cada amostra físico-química analisou-se: Potencial de hidrogênio (pH), Temperatura (T), Oxigênio Dissolvido (OD), Sólido Totais Dissolvidos (STD) e Condutividade Elétrica (CE). Para as análises microbiológicas as amostras foram coletadas utilizando recipientes previamente esterilizados, e a sua quantificação foi realizada usando de análise de membrana e Placa de Alta Sensibilidade 3M™ Petrifilm™ para identificar a presença de coliformes totais e Escherichia coli. Os dados foram interpretados usandoanálise estatística, realizando o teste de variância (ANOVA) e equivalentes não paramétricos (Mann Whitney e Kruskal wallis). A partir de cada análise, os valores de CE e STD apresentaram-se relativamente baixos, não evidenciando níveis de contaminação nesses poços, embora tenha sido identificada a presença de c. totais e E. coli, fato que limitaria o uso deste recurso para consumo humano. Os parâmetros em desacordo com valores de potabilidade podem estar relacionados com hábitos e manuseio inadequado na captação de água, além da falta de proteção desses poços com profundidade rasa de aquífero livre, pois, estão susceptíveis à entrada de poluentes derivadas de atividades antrópicas potencialmente poluidoras. The evaluation of the quality of the water in the wells in the rural communities of the Archipelago of Marajó island - PA A B S T R A C TThe study deals with the evaluation of the quality of the water in the wells that are used by the rural communities in the archipelago of the Marajó island (PA), based on the analysis of the physico-chemical and microbiological. The water samples were collected according to the technical standards in force, during the period of the highest rainfall in the region, with a temperature of 23°C and 32 °C. For each sample, of analysis: the Potential of hydrogen (pH), Temperature (T), Dissolved Oxygen (OD), a Solid-Total solids content (a STD) and Electrical Conductivity (EC). For the microbiological analyses of the samples were collected using containers, pre-sterilized, and the quantification was carried out using the analysis of the membrane and the Plate of the High Sensitivity of the 3M™ Petrifilm™ to identify the presence of total coliforms and Escherichia coli. The data were interpreted by using a statistical analysis, using the test of variance (ANOVA), and the equivalent non-parametric (Mann Whitney e Kruskal wallis). From each analysis, the values of CE and STD showed to be relatively low, the levels of contamination in these wells, even though it has been identified that the presence of c. total and E. coli, a fact that woulding limit the use of water for human consumption. All the parameters are at odds with the values of drinking may be related to habits, and improper handling on the water, in addition to the lack of protection from these wells with the depth of the shallow aquifer is free, therefore, they are susceptible to the entry of any pollutant derived from anthropogenic activities.Keywords: Rural population; water resources; vulnerability.

This study identified and mapped worldwide surveillance actions and initiatives of drinking water quality implemented by government agencies or public health services. The scoping review was conducted between July 2021 and August 2022 based on the Joanna Briggs Institute. The search was performed in relevant databases and grey literature; 49 studies were obtained. Quantitative variables were presented as absolute and relative frequencies, while qualitative variables were analyzed using the IRaMuTeQ software. The actions developed worldwide and their impacts and results provided four thematic classes: (1) assessment of coverage, accessibility, quantity, and drinking water quality in routine and emergency situations; (2) analysis of physical-chemical and microbiological parameters in public supply networks or alternative water supply solutions; (3) identification of household water contamination, communication, and education with the community; (4) and investigation of water-borne disease outbreaks. Preliminary results were shared with stakeholders to favor early knowledge dissemination.

“…According to the national water authority (Agência Nacional de Águas e Saneamento Básico -ANA), Pará's water bodies have no public management directives, no state planning, or there is not even a public billing policy for water usage (ANA, 2013a). The water sources are mostly superficial, which makes them susceptible to contamination by sewage, residential septic tanks and leaching (Vasconcelos et al, 2016), which contributes to the spread of water-borne diseases. Only 25% of all Pará's municipalities have 55% or more of its sewage collected and treated, while half of them rely on mainly non-treated sewage (ANA, 2013b).…”

Hepatitis-A virus is a worldwide healthcare problem, mainly affecting countries with poor sanitary and socioeconomic conditions. This communication evaluates the spatiotemporal variability of the disease’s socioepidemiological profile in one of the endemic Brazilian regions (Pará State) prior to (2008-2013) and after (2014-2017) the launch of the national public vaccination programme. Hepatitis-A epidemiological reports concerning Pará State - Brazil - were used for this study including municipalitylevel data of the disease’s reported positive notification cases (PNCs). The analyses involved socioepidemiological profiling and space-time scan statistics. A total of 5500 PNCs were reported in the study period. On average, PNCs decreased over time throughout the state, with strongest drops after 2015. The PNCs were specific for gender, race/ethnic origin and age group. The predominant gender and race/ethnic groups was male and brown, respectively. While children were the most susceptible age group prior to 2015, there was a shift towards older ages (young and adults) in later years. Those found to be the most affected by the disease, as shown by space-time scan statistics, were people in densely populated municipalities with unsatisfactory sanitary conditions and also less well covered by the public vaccination programme. Despite drops in the number of hepatitis-A PNCs, thanks to the national vaccination programme, the disease still persists in Pará State and elsewhere in Brazil. The present study reinforces the need of continuous prevention and control strategies for effective control and erradication of hepatitis-A.
