TLDR
In this paper, the authors investigated the effect of electrochemically activated water on biofilm contamination in dental unit water lines and concluded that distilled water was ineffective in controlling bacterial counts and biofilm.Abstract:
Objective To investigate the effect of electro-chemically activated water on biofilm contamination in dental unit water lines. Design Thirteen dental units fitted with independent water systems and used for 12 years with distilled water were divided into two groups, A and B. At the start, one week later, and again four weeks later, the bacterial counts in water from all units were determined. Also specimens of tubing were taken from the units at the beginning and at the end of the study for SEM investigation. In Group A distilled water was replaced with electrochemically activated water (a Russian invention), and used continuously for the duration of the study. In group B, distilled water was used as before, until confirmed to be contaminated. For ethical reasons group B was treated, one week into the study with conventional disinfectants. Setting The project was carried out in a clinic of a department of periodontology of a faculty of dentistry during 1998. Results Both groups showed a marked reduction in bacterial counts. Under SEM Group A showed a total elimination of the biofilm and Group B a partial removal. Conclusions Distilled water was ineffective in controlling bacterial counts and biofilm. Electrochemically activated water was effective for this purpose.read more

TL;DR: The efficacy of neutral electrolysed water (NEW) in reducing Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Listeria monocytogenes on glass and stainless steel surfaces is compared with that of a sodium hypochlorite solution with similar pH, oxidation–reduction potential (ORP) and active chlorine content.

A new medium for the enumeration and subculture of bacteria from potable water.
TL;DR: Results from parallel studies with spread, membrane filter, and pour plate procedures showed that R2A medium yielded significantly higher bacterial counts than did plate count agar, and the magnitude of the count was inversely proportional to the incubation temperature.
