| Abstract |
Coliforms were enumerated by using m-Endo agar LES and m-T7 agar in 102 routine samples of drinking water from three New England community water systems to investigate the occurrence and significance of injured coliforms. Samples included water collected immediately after conventional treatment, during the backwash cycle, at various points in the distribution system, and 1 week after the break and subsequent repair of a distribution main. Injured coliforms in these samples averaged >95%. m-T7 agar yielded 8- to 38-fold more coliforms than did m-Endo agar LES. (Copyright (c) 1986, American Society for Microbiology.) |
