Abstract Introduction: The quality of water in hemodialysis services is critical in avoiding health risks in patients with renal insufficiency. Objective: To monitor the microbiological quality of treated water samples from hemodialysis services in the city of Rio de Janeiro. A total of 480 water samples were collected for microbiological analysis and 192 for endotoxin testing from 96 hemodialysis clinics between 2016 and 2018 by the Sanitary Surveillance of the city of Rio de Janeiro. Method: Methodologies described in the Brazilian Pharmacopoeia, DRC nº 11 2014 and Consolidation Ordinance nº 5, 2017. Results: Twenty percent of the microbiological analysis samples showed a high number of Heterotrophic Plate Count Bacteria (> 100 UFC/mL) and 24% of the endotoxin search (LAL) presented values above the recommended value (> 0.25 EU/mL). Seventy-eight percent of the clinics (75/96) were unsatisfactory, 41 for high BH and 34 for LAL. A total of 563 isolates were identified by confirmatory biochemical tests as: Pseudomonas aeruginosa (35.5%), Burlkolderia cepacia (21.3%), Stenotrophonomas maltophilia, (19.1%), Acinetobacter baumannii (15.1%) and Ralstonia pickettii (9.0%). Conclusions: Our results allow us to conclude that systematic monitoring of water quality in hemodialysis services is essential to provide safety and prevent health problems patients.
