A total of 339 water samples obtained from 90 locations in Korea from 2007 to 2011 were tested for the presence of enteric viruses (EV), total coliforms (TC), and fecal coliforms (FC). A total culturable virus assay revealed that 89 samples (26.3%) were positive for EV, and the average concentration was 5.8 most probable number (MPN)/100 L. The H-river basin exhibited the highest contamination of EV (occurrence, 41.3%; average concentration, 24.0 MPN/100 L). EV contamination was higher in river water (concentration, 8.4 MPN/100 L; occurrence, 33.6%) than in lake water or groundwater. The concentration of EV was the highest in the spring (7.7 MPN/100 L), while the occurrence of EV was highest in the winter (36.1%). The number of TC showed a range of 0-1.2 × 10(5) colony forming units (CFU)/100 mL, and the number of FC exhibited a range of 0-6.2 × 10(3) CFU/100 mL per sample. Statistical analyses showed that EV, TC, and FC did not significantly correlate with temperature or turbidity. In addition, TC and FC showed no significant correlation with EV. In conclusion, TC and FC may not be accurate microbial indicators of waterborne EV in Korean aquatic environments.
