The water supply is an important source for transmition of pathogenic microorganisms, since during the distribution fecal pollution may occur. Thermotolerant and total coliforms are the main groups of bacteria used as indicator of pollution and Escherichia coli is the main bacterium used as a parameter of fecal pollution. According to ANVISA resolution N ° 2914/2011 (Ministry of Health), a safe drinking water, for human consumption, the water presenting microbiological, physical, chemical and radioactive standards, safe to human health. The aim of this study was evaluate bacteriological conditions, residual chlorine and pH of water samples, collected from drinking fountains at the Campus of Universidade Estadual de Londrina (UEL) during 2011. Nineteen samples were analyzed for the presence of total coliforms and E. coli by Colilert technique, points more frequently used by people were selected. The results showed no contamination by E. coli or total coliforms. Values for residual chlorine and pH were in accordance to ANVISA resolution. However, monitoring program for evaluating bacteriological quality of water from drinking fountains is important to avoid contamination of bacteria which could be a risk for the health of students and employees of UEL.Downloads
