Physico-chemical and microbiological standards of water springs and shallow wells on rural properties in the southwest region of Paraná

Abstract

This study evaluates the quality of water in rural farms of Dois Vizinhos, Paraná, Brazil, by physico-chemical 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.
