Abstract:
The water for human consumption is the main vehicle for the transmission of pathogens that are capable of causing enteric parasitic diseases; therefore, its microbiological control is vital. This work had the purpose of evaluating the bacteriological quality of drinking water, in terms of the presence of total and thermotolerant coliforms, in different Feeding Units in the city of Recife, Pernambuco State, according to the potableness standards established by Ordinance No. 518 of 2004 of the Brazilian Ministry of Health/ANVISA. Forty water samples were collected in the Feeding Units located near the UFPE and UFRPE. The bacteriological tests for research on total and thermotolerant coliforms were carried out in accordance with the protocol of APHA (1995). Of the analyzed samples, 62.5% presented total coliforms and 42.5% thermotolerant coliforms. According to the results obtained, 62.5% of the samples are not in compliance with the law in force.
