Padrão físico-químico e microbiológico da água de nascentes e poços rasos de propriedades rurais da região sudoeste do Paraná

Abstract: ABSTRACT:This study evaluates the quality of water in rural farms of Dois Vizinhos, Paraná, Brazil, by physicochemical and microbiological analyses. A total of 90 samples were analysed, 45 from water springs and 45 from shallow wells, regarding the following parameters: pH, temperature, turbidity, total and thermotolerant coliforms. Of the 90 samples analysed, 23 met the current legislation, while 67 disagreeded with it, being unsuitable for human and animal consumption and a health risk factor. KEYWORDS

“…The temperature of the collected samples varied from 21 °C to 28 °C, being 25 °C to 21 °C for sample A and 28 °C for 20° C for sample B. Temperature is very important, since it influences the biological processes, chemical and biochemical reactions, as well as the solubility of the dissolved gases, conductivity and mineral salts in the water (MACEDO, 2004;DANELUZ;TESSARO, 2015). The abrupt temperature variation from the first to the second collection can be explained by the time of the day of collection, since the clouds were blocking the solar radiation, as well as the incidence of small rainfall.…”

“…Além dos parâmetros relatados acima, para o consumo de água de nascente, é necessária a avaliação microbiológica, cuja presença pode estar relacionada a excrementos de animais (FIGUEIREDO, 2013;DANELUZ;TESSARO, 2015).…”

“…presença desses organismos na água pode estar associada a excrementos de animais, uma vez que a área onde a fonte se encontra não está isolada e recebe grande contribuição pluvial do loteamento e de área agrícola vizinha(FIGUEIREDO, 2013;DANELUZ; TESSARO, 2015).…”

“…Segundo Daneluz & Tessaro (2015) na periferia da área urbana, as águas subterrâneas oriundas de poços rasos constituem uma importante fonte de suprimento de água para consumo doméstico, humano e animal. Apesar do intuito do fornecimento de condições mínima de sobrevivência a utilização dessas águas representa temeridade à saúde pública.…”
