Abstract

N-Nitrosodimethylamine (NDMA) is a potent carcinogen that has been detected in effluent from conventional and advanced wastewater treatment systems. The presence of NDMA in systems where indirect potable water reuse is practiced is a concern. NDMA precursors are a concern because they can produce NDMA when chloramines are used for disinfection. Prior to this project, little was known about the potential for loss of NDMA and NDMA precursors under conditions experienced in water reuse programs. The project assesses the fate and transport of NDMA and NDMA precursors in soil, groundwater and surface waters.

Originally funded as WERF project Reuse-02-02.
