Water is an indispensable element in people's lives, but it can bring health risks. There are few studies on waterborne parasites, most of them reports on Coliform bacteria. Thus, parasitological analysis of water from drinking fountains plays a key role, as children, adolescents and young people spend most of their day in these educational institutions. Thus the objective of this work was to evaluate the contamination by parasites in waters from drinking fountains located in educational institutions in the city of Serra Talhada - PE. The experiment was based on the principles of the spontaneous sedimentation technique of Hoffman, Pons and Janer (1934). Thirty water samples were collected from ten educational institutions. The collection took place in the morning and was randomly drawn from both the water cooler and the tap, once collected were analyzed at the Biology Laboratory of the Rural Federal University of Pernambuco Serra Talhada Academic Unit (LABIOO). The results showed that 20% (6/30) of the samples showed positive results for protozoan, nematode and arthropod. According to the results it was also possible to observe the diversity among the drinking fountains in the educational institutions, as well as the observation of the conditions of these drinking fountains. It is concluded that there is a prevalence of parasites in drinking fountains belonging to educational institutions, and should be zero the amount of parasites found in water, since this is for human consumption.
