It is well known that unchlorinated municipal wastewater contains high levels of organic and inorganic amino nitrogen compounds, the single most abundant amino-N species being ammonia. Upon chlorination, these compounds are transformed almost instantaneously and quantitatively into N-chloramino derivatives. The organic chloramines have been shown to

interfere with disinfection and have lower disinfection capacities than their inorganic counterpart monochloramine. The environmental effects imposed by the discharge of these compounds into natural receiving waters is unknown. This study has shown that amino acid precursors for N-chloramino acids range in concentration from 1.4 X 10-7 M to 9.0 X 10-7 M on a given day. The N-chloramines identified as forming in chlorinated municipal effluents are N-chloroglycine, N-chloronorvaline, N-chlorovaline, N-chloromethylamine, and N-chlorodimethylamine. Techniques employed in the identification of the amino acid precursors and the N-chloramines included derivatization to produce fluorescent compounds followed by HPLC with fluorescence detection, GC, and GC/MS.
