Amino acids (AAs) are known precursors to regulated
and unregulated disinfection byproducts
(DBPs). Nitrogenous DBPs are of concern in the
drinking water industry because they can be more
geno- and cytotoxic than many of the currently regulated
carbon-based DBPs. The authors measured
occurrences and removals of AAs in raw water and
filter effluents from 16 full-scale drinking water treatment
plants that treat water impaired by upstream
wastewater discharge or algal growth. The AAs measured
in this study accounted for only a small portion
of the dissolved organic nitrogen (DON) pool and
were removed, to a high degree, during drinking
water treatment.
This work illustrates that although amino acids
can account for a more significant portion of the
DON pool in natural lakes and streams, the influence
of wastewater discharge and algal activity
produce a pool of organic nitrogen not likely to
account for all of the nitrogenous DBPs. This
unidentified DON warrants identification and further
study. Includes 61 references, table, figures.
