Formatted abstract
A survey of disinfection by-product
(DBP) occurrence was conducted at
the Capalaba Water Treatment Plant
(WTP) in Brisbane and at 19 sampling
points of the distribution system for
six months through spring-summer
2011. In addition to currently regulated
DBPs including N-nitrosodimethylamine
(NDMA), DBPs that were reported as
high priority due to potential toxicity were
studied. These priority DBPs included five
iodinated trihalomethanes (THMs), four
haloacetonitriles (HANs), two haloketones
(HK), chloronitromethane and chloral
hydrate (CH). Results showed that all the
measured regulated DBPs, including CH,
were below the Australian Drinking Water
Guidelines
(ADWG) recommendations.

THM speciation followed the
order trichloromethane (TCM) >
bromodichloromethane (BDCM) >
dibromochloromethane (DBCM) >
tribromomethane (TBM) in waters
provided by the Capalaba WTP. The
order was DBCM>BCDM>TBM>TCM for
waters provided by the North Stradbroke
Island (NSI) WTP as a result of different
dissolved organic carbon/bromide
(DOC/Br) ratios. HANs were measured
at the WTP and across the distribution
system at significant concentrations,
but still lower than the World Health
Organization (WHO) recommendations
in the case of dichloroacetonitrile
and dibromoacetonitrile. Speciation
of brominated and chlorinated HANs
followed the trends observed for THMs.
The formation of iodinated-THMs
was low, in agreement with the iodide
concentration measured. NDMA was not
detected above the limit of detection
(5 ng/L). NDMA formation potential of
source water at the Capalaba WTP was
11.4 ± 3.4 ng/L, which is well below the
ADWG (i.e., 100 ng/L).
