Resumo: | This paper presents data obtained on microbiological and physico-chemical analysis of 4347 public water supply samples from 88 municipalities in the Northeast region of the state of São Paulo, carried out within a year. In microbiological analysis, 288 samples showed positive results for indicator microorganisms, occurring an increase of 80% in the rainy season compared with the dry period. Physico-chemical analysis: in 1514 samples, lithium concentration was equal to or higher than the detection limit of the method; the nitrate concentration was greater than the maximum value allowed in 17 samples; 1730 samples showed fluoride content out-of-range of drinking pattern; bromate concentration was greater than the maximum value allowed in 16 samples; the pH value was outside the range recommended in 161 samples; 292 samples showed levels of free residual chlorine (FRC) outside the recommended range; 17 samples showed apparent color values above the maximum allowed; 13 samples showed turbidity values above the maximum allowed. By means of principal components analysis, it was possible to discriminate the waters of the region, with the formation of groups of municipalities with similar physico-chemical profiles, generating a mapping based on prominent variables. |

Nos ensaios microbiológicos, 288 amostras apresentaram resultado positivo para microrganismos indicadores, ocorrendo um acréscimo de 80% no período de chuvas em comparação com o período de seca. Nos ensaios físico-químicos: em 1.514 amostras, a concentração de lítio foi igual ou superior ao limite de detecção do método; a concentração de nitrato foi superior ao valor máximo permitido em 17 amostras; 1.730 amostras apresentaram teor de fluoreto fora da faixa do padrão de potabilidade; a concentração de bromato foi superior ao valor máximo permitido em 16 amostras; o valor de pH situou-se fora do intervalo recomendado em 161 amostras; 292 amostras apresentaram teores de cloro residual livre fora da faixa recomendada; 17 amostras apresentaram valores de cor aparente acima do máximo permitido; 13 amostras apresentaram valores de turbidez acima do máximo permitido. Através da análise de componentes principais foi possível discriminar as águas de abastecimento da região, com a formação de grupos de municípios com águas de perfis físico-químicos similares, gerando um mapeamento baseado em variáveis proeminentes.Instituto Nacional de Controle de Qualidade em Saúde2017-05-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion"Peer-reviewed article""Artículo revisado por pares""Artigo avaliado pelos pares"application/pdfapplication/pdfhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/86210.22239/2317-269X.00862Health Surveillance under Debate: Society, Science & Technology ; Vol. 5 No. 2 (2017): May; 53-63Vigilancia en Salud en Debate: Sociedad, Ciencia y Tecnología; Vol. 5 Núm. 2 (2017): Puede; 53-63Vigil Sanit Debate, Rio de Janeiro; v. 5 n. 2 (2017): Maio; 53-632317-269Xreponame:Vigilância Sanitária em Debateinstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporenghttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/862/381https://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/862/457Copyright (c) 2017 Vigilância Sanitária em Debate: Sociedade, Ciência & Tecnologia (Health Surveillance under Debate: Society, Science & Technology) – Visa em Debatehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessDovidauskas, SergioOkada, Isaura AkemiIha, Maria HelenaCavallini, Álvaro GennariOkada, Marina MiyukiBriganti, Rita de CássiaBergamini, Alzira Maria Moratode Oliveira, Maria Aparecida2023-06-27T15:19:44Zoai:ojs.visaemdebate.incqs.fiocruz.br:article/862Revistahttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebatePUBhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/oaiincqs.visaemdebate@fiocruz.br || gisele.neves@fiocruz.br2317-269X2317-269Xopendoar:2023-06-27T15:19:44Vigilância Sanitária em Debate - Fundação Oswaldo Cruz (FIOCRUZ)false |
