The first objective of this project was to examine the impacts of seasonal variations and some climatic events on (1) the occurrence of N-nitrosodimethylamine (NDMA) precursors in selected water sources, (2) the removal of the NDMA precursors by conventional treatment processes optimized currently for controlling the regulated THM and HAA formation, and (3) the formation of NDMA in distribution systems. The second objective was to examine the effectiveness of an integrated pre-oxidation strategy for NDMA control during the seasonal variations and climatic events at water sources.
