| 520 | 3 |a"Samples of drinking water collected from three different sources were tested for total coliforms, fecal coliforms and coliphage concentrations. Five samples from each site were tested with and without dechlorination procedures. Results showed that nine of the samples were positive for coliphage while being negative for total and fecal coliforms, another nine samples were positive for all three parameters. In no instance were total coliform and fecal coliform counts found without coliphage also being found. Results of this study indicate that coliformn counts are not fully protective of treated drinking water and the presence of coliphage in these waters could be an indication of the presence of other viruses"--Abstract. |
