Disinfection by-products (DBP) are an ever-present nuisance in the efforts to purify drinking water, wastewater, and municipal waters from various sources. An emerging class of DBP compounds with health effects is nitrosamines which result from chloramination or chlorination if the water is nitrogen-rich. Five of these nitrosamines have been listed on the US EPA’s new Contaminant Candidate List (CCL-3). Of the nitrosamines, the most common and problematic is N-nitrosdimethylamine (NDMA). The maximum admissible levels set by the US EPA are 7 ng/L for NDMA and 2 ng/L for N-nitrosodiethylamine (NDEA).
