Abstract

To assess possible risks from the consumption of drinking water from various sources, a survey of the microbiol. quality of tap water, com. bottled drinking water which is exploited from natural mineral water, and natural spring water was conducted. A total of 4 different brands of com. bottled drinking water, and 4 types of spring water from different sources, and tap water from 4 private houses were tested for 4 index microorganisms, and the microbial quality changes of the water during the storage at room temp. or refrigerated temp. for 7 days. Aerobic plate counts of all of the initial water samples were still within 100 CFU/mL (drinking water std. of Korea). Total coliforms, fecal coliforms, and E. coli were not detected in all of the water samples at initial. However, aerobic plate counts of 3 types of spring water and three types of bottled drinking water stored at room temp. showed higher levels than the stds. in 5 days. Total coliforms were detected in 3 types of spring water after 1 day storage at room temp., and in one type of bottled drinking water after 5 days storage. These results indicate that some of the spring water surveyed are not safe to drink, and the spring water and bottled drinking water after opening the lid should not be stored at room temp., if they are used for drinking.
