ABSTRACT: Significant fractions of bromine-substituted disinfection byproducts
(DBPs)—particularly trihalomethanes (THMs)— have been observed to form during
treatment of water from the Missouri River. THM speciation was also noted to follow
a seasonal pattern during a 2.5-year period, during which
samples were collected multiple times per month. Although some treatment
processes were effective at reducing the chloroform formation potential, no
treatment used at this utility significantly reduced the formation of the three
bromine-substituted THM species. Using chloramination rather than free
chlorination for secondary disinfection, however, was effective at limiting
increases in the concentration of all four regulated THM species in the
distribution system.
