Resumo: This study was conducted in order to evaluate the water quality of protected and non protectedsuperficial sources of two municipalities in western Santa Catarina, Brazil, the most important swine production area in this state. Sixty-four sources from Arvoredo and 73 ones from Saudades were analyzed. The parameters considered in this study were total and fecal coliforms, nitrate, ammonia, orthophosphate and pH levels. It wasobserved the occurrence of contamination for fecal coliforms deriving from animal dejections in 49,3% of the water sources from Saudades and 73,4% of those from Arvoredo. In 9,6% of the water sources from Arvoredo and 4,9% from Saudades, the levels of nitrate were above 10mg/L. Fourty-six percent of the sources from Arvoredo and 27% from Saudades presented high levels of orthophosphate. In protected sources, the alteration in theparameters occurred in lower ratios, suggesting the difference in water quality between these two municipalities is due to the higher percentage of proteted sources (51% in Saudades compared to 27% in Arvoredo).

O objetivo deste trabalho foi determinar a qualidade da água não tratada oriunda de fontes superficiais a céu aberto e protegidas, em dois municípios do Oeste Catarinense representativos do sistema de criação intensivo de animais empregado na região. Foram analisadas 64 fontes no município de Arvoredo e 73 fontes no município de Saudades. Os indicadores considerados foram coliformes fecais e totais, nitrato, amônia, orto-fosfato e pH.Constatou-se a ocorrência de contaminação por coliformes fecais, oriundos dos dejetos animais, em 49,3% das fontes de Saudades e 73,4% das fontes de Arvoredo. Em 9,6% das fontes de Arvoredo e 4,9% das fontes de Saudadesforam encontrados níveis de nitrato acima de 10mg/L. Em 46,3% das fontes de Arvoredo e 27% das fontes de Saudades foram encontrados níveis de orto-fosfato acima de 0,025mg/L, que é o valor máximo permitido (VMP),caracterizando este elemento como um bom indicador químico da poluição agrícola na região. Nas fontes protegidas, as alterações nos indicadores ocorreram em menor proporção, levando a concluir que a diferença dequalidade da água entre os municípios deve-se ao percentual de fontes protegidas de 51% em Saudades e 27% em Arvoredo.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2021-07-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1015Agropecuária Catarinense Journal; Vol. 17 No. 3 (2004); 68-71Agropecuária Catarinense; v. 17 n. 3 (2004); 68-712525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1015/911Copyright (c) 2004 Agropecuaria catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBaldissera, Ivan TadeuBorsatto, Miria Tereza 2021-07-28T17:17:09Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1015Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2021-07-28T17:17:09Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
