초록
This study was performed to investigate the quality for microorganisms of water purifiers set up public places used lots of people which in public office, welfare facilities, public bath, school. The water purifiers were installed near the entrance and where they are easily found. None of them were installed at where they should not be installed at the locations stated by law. Heterotrophic plate count at public office, welfare facilities,public bath, school was 0~3,700 CFU/mL, 0~3,400 CFU/mL, 0~3,500 CFU/mL, 0~2,300 CFU/mL respectively. Total coliforms was not detected at public office and school, but found at welfare facilities and public bath. Fecal coliforms was not detected anywhere. The rates bellowing the drinking water quality at public office, welfare facilities, pubic bath, school are 36%, 28.7%, 22.9%, 9.5% respectively. Species of heterotrophic bacteria isolated from public office water purifiers was Micrococcus Luteus, Sphingomonas paucimobilis, Ralstonia mannitolilvtica, Pseudomonas fluorescens etc. Most of bacteria found during the testing are common bacteria that exist in typical living environment.
Abstract
This study was performed to investigate the quality for microorganisms of water purifiers set up public places used lots of people which in public office, welfare facilities, public bath, school. The water purifiers were installed near the entrance and where they are easily found. None of them were installed at where they should not be installed at the locations stated by law. Heterotrophic plate count at public office, welfare facilities,public bath, school was 0~3,700 CFU/mL, 0~3,400 CFU/mL, 0~3,500 CFU/mL, 0~2,300 CFU/mL respectively. Total coliforms was not detected at public office and school, but found at welfare facilities and public bath. Fecal coliforms was not detected anywhere.
