In order to investigate whether or not Total Coliforms(T.C.) and Fecal Coliforms (F.C.)
are compatible as indicator microorganisms of waterbome enteric viruses, a total of 192
surface water samples from 24 locations in korea were tested for T.C., F.C., and human
enteric viruses from July 2003 to January 2006. Altogether, the number of T.C. in each
samples was ranged from 0~5.3×10⁴colony forming unit(CFU)/100mL, and the number of
F.C. ranged from 0~5.0×10³CFU/100mL per sample. Thirty-three percent of the samples
tested positive for human enteric viruses after the total culturable virus assay. The
results of the statistical analysis showed that T.C. and F.C. had a significant
correlation with turbidity and temperature, but the waterborne enteric viruses did not.
When compared to the number of T.C. or F.C. per sample, the concentration of
waterborne enteric viruses was not found to be correlated. In conclusion, it is
suggested that T.C. and F.C. may not be sufficient microbial indicators of waterborne
enteric viruses in the samples analyzed in this study. However, further research is
needed to find other microbial indicators of waterborne enteric viruses and to develop
more advanced and sensitive methods to detect waterborne enteric viruses.
