Abstract

 Introduction: Provision and supply of safe DRINKING WATER for armed forces is a very important health issue that can affect a countrys military power. DISINFECTION methods of DRINKING WATER include: CHLORINATION; ozonation; flouridation; U.V; boiling and use of chlorine dioxide or a combination of these methods. This survey aimed at assesssing the DISINFECTION methods of DRINKING WATER in MILITARY CENTERS affiliated to Sepah.Material and Methods: 182 centers from across the country were randomly sampled in this descriptive study. Data, having been collected with a questionnaire, were analyzed with SPSS software.Results: Of the182 centers, the highest and lowest frequencies were 46.7% and 3.8%from Moghavemat Forces and the Navy, respectively. DRINKING WATER was supplied in 63.7% of the cases from tap water, in 25.3% of the cases from well water and in 11% of the cases from other sources. Only 38.7% of the centers chlorinated their DRINKING WATER. Half of the 63.4% of the centers that performed chlorimetry reported no RESIDUAL CHLORINE. 50% of the centers that chlonirated their own water supplies failed to add sufficient chlorine to the water. In 65% of the centers outfitted with hypochlorinator systems, the system operators were not sufficiently trained.Discussion: Surveying of DRINKING WATER quality is one of the most important health research subjects. The results of this study show that RESIDUAL CHLORINE in dinking water in many centers was not enough. The concentration of RESIDUAL CHLORINE is estimated to be lower than the standard level. The absence of free available chlorine (FAC) in DRINKING WATER is indicative of possible contamination and the concomitant increase in the incidence of waterborne diseases.Although DISINFECTION is a vital process in DRINKING WATER treatment, some of the above-mentioned centers failed to perform it because either there was no equipment or the available equipment was inoperative. Monitoring the quality of DRINKING WATER through microbial sampling methods, daily CHLORINATION and detection of contamination sources is necessary. Our results indicate that the qualitiy of DRINKING WATER in Sepah centers is not up to standard. Needless to say, provision of DRINKING WATER with the highest quality is of outmost importance.
