The main objective is to analyze the quality of water intended for human consumption (hand hygiene) within emergency hospital services, focusing on bacteriological aspects, and to compare it with potability standards established by current legislation, specifically under Ordinance MS No. 888/2021. The results revealed that the water collected within hospitals is not suitable for hand hygiene, as total coliforms and E. coli were detected. The study highlights monitoring and water treatment strategies used successfully in other countries, suggesting that investing in continuous water monitoring and treatment within hospitals is a key strategy for ensuring safe hand hygiene and controlling nosocomial infections.PPGCA - Meio ambiente e sustentabilidade
