Nitrosamine Precursors in Direct and Indirect Potable Reuse Water

There is growing interest in nitrosamines, including N-nitrosodiethylamine (NDEA), and their precursors. This project will apply an existing analytical method typically used for N-nitrosodimethylamine (NDMA) to seven additional nitrosamines. As nitrosamines in the finished water are identified, the analytical methodology will be modified to search for and identify precursors associated with these nitrosamines. This project will increase understanding of the importance of NDEA and other nitrosamines in finished reclaimed water and their occurrence through a typical full advanced treatment train.

This project builds upon the National Science Foundation project Securing the Future of Direct and Indirect Potable Reuse: N-nitrosodimethylamine (NDMA) Formation Pathways and Precursors.
