Abstract

TECHNICAL NOTES
The Manchester, New Hampshire water treatment plant employs granular activated carbon and full conventional treatment. An 18 month sampling program to determine the effect of GAC upon finished water microbial quality was conducted. The GAC bed itself promoted the regrowth of standard plate count organisms, but had no effect on coliforms, endotoxins, or acidfast organisms. This regrowth did not occur in a rapid sand filter immediately upstream of the GAC contactor. The regrowth of organisms within the GAC bed could be correlated with temperature, and chlorine residual. Following terminal chlorination, the increased microbial levels were reduced and no problems attributable to GAC were noted in the subsequent distribution system.
