Objective: This study was performed in order to investigate the distribution of antibiotic resistant E. coli andwater quality in waterscape facilities. Methods: Nine waterscape facilities were selected and classified into three types: ground, wall and generalfountain. The items analyzed in this study were pH, turbidity, KMnO4 consumption, total colony, total coliforms,fecal coliforms and E. coli. Additionally, an antibiotic resistance test on E. coli was performed. Results: There were no sampling sites that exceeded the permitted limits of water quality, but the concentrationof pollutants was high at the beginning operation in June. Moreover, concentration of turbidity, KMnO4consumption and total colony were higher in ground fountains than in wall and general fountains. Five speciesof antibiotic resistant E. coli were detected from three sampling sites. Conclusions: The waterscape facilities were significantly contaminated with water microorganisms, especiallytotal colony, total coliforms and fecal coliforms. Disinfection and filtration systems to remove pollutants shouldbe installed for safe waterscape facilities.
