Abstract

RESUMO O objetivo desta pesquisa foi avaliar a água bruta de fontes quanto à cor, ao pH, ao nível de amônia e à presença de coliformes totais e fecais, a qual é usada para fins de abastecimento domiciliar e na agroindústria alimentar regional do Planalto Catarinense - Santa Catarina, acordando com a Portaria no 2.914/2011 do Ministério da Saúde. As discussões permitiram concluir que a cor da água se apresentou abaixo do padrão máximo permitido; constatou-se baixa concentração de amônia; o pH apresentou variável entre 5,5 e 7,5 e algumas amostras apresentaram contaminação por coliformes fecais. Desta forma, o presente trabalho demonstrou a necessidade de notificação e orientação aos proprietários rurais para a desinfecção da água para evitar a presença de quaisquer agentes patogênicos.ABSTRACT The objective of this research was to evaluate the raw water sources as for the color, pH, ammonia level and presence of total and faecal coliforms.
