In a 30-month prospective study, we evaluated the efficacy of chlorine dioxide to control Legionella organisms in a water distribution system of a hospital with 364 patient beds and 74 skilled nursing beds. The number of hot water specimens positive for Legionella organisms decreased from 12 (60%) of 20 to 2 (10%) of 20. An extended time (18 months) was needed to achieve a significant reduction in the rate of Legionella positivity among hot water specimens. At the time of writing, no cases of… 
Legionella control by chlorine dioxide in hospital water systems
TLDR
It is indicated that ClO2 is a promising disinfectant for controlling not only Legionella, but also other microorganisms in drinking water.
Legionella control by chlorine dioxide in hospital water systems
TLDR
Chlorine dioxide is a promising alternative disinfectant for hospital water systems to prevent Legionnaires’ disease and copper–silver ionization has been an effective disinfection method, but a recent study showed that Legionella could develop resistance to copper and silver ions.
Controlling Legionella in Hospital Drinking Water: An Evidence-Based Review of Disinfection Methods
TLDR
This review evaluates systemic disinfection methods (copper-silver ionization, chlorine dioxide, monochloramine, ultraviolet light, and hyperchlorination), a focal disinfection method (point-of-use filtration), and short-term disinfections methods in outbreak situations (superheat-and-flush with or without hyperchlorinated).
Water quality supply in a Portuguese teaching hospital: monitoring and studies on detection of critical points
TLDR
A suitable plan for drinking water quality was instituted which resulted in reducing microbiological growth in the waterwork network, improving public health protection, however, the detection of critical points associated with lower levels of free Cl were found on certain floors/points-of-use, requiring the need to improve the monitoring water treatment system and/or implementation of additional technologies.
Hospital-acquired Legionella infections: an update on the procedures for controlling environmental contamination.
TLDR
Water disinfection is not generally sufficient to control the risk of infection, but a complex water safety plan should be developed, including system maintenance, training of staff and implementation of a clinical surveillance system aimed at early detection of cases.
Preventing Healthcare-Associated Legionellosis: Results after 3 Years of Continuous Disinfection of Hot Water with Monochloramine and an Effective Water Safety Plan
TLDR
The implementation and application of a WSP in a hospital, together with the disinfection of the water distribution system with monochloramine, can be effective in controlling the growth of Legionella and in preventing nosocomial Legionella.

A 17-Month Evaluation of a Chlorine Dioxide Water Treatment System to Control Legionella Species in a Hospital Water Supply
TLDR
The results indicate that chlorine dioxide may hold promise as a solution to the problem of Legionella contamination of hospital water supplies, as levels of chlorine dioxide and chlorite were below EPA limits.
EVALUATION OF CHLORINE DIOXIDE IN POTABLE WATER SYSTEMS FOR LEGIONELLA CONTROL IN A ACUTE CARE HOSPITAL ENVIRONMENT
The Johns Hopkins Hospital in 1999 began to evaluate the safety and efficacy of chlorine dioxide for Legionella control in a potable water system in an acute care hospital environment. The evaluation
keeping Legionella out of water systems
TLDR
Study of a hospital where three cases of hospital‐acquired Legionnaires' disease were detected in less than two years, chlorine dioxide (ClO2) was considered a cost‐effective approach to disinfection given that ClO2 generators could treat the 23 buildings comprising the hospital complex from one central location.

TLDR
Copper-silver ionization is now the only disinfection modality to have fulfilled all four evaluation criteria and no cases of hospital-acquired legionnaires' disease have occurred in any hospital since 1995.
