Removal and/or Destruction of NDMA in Wastewater Treatment Processes

N-nitrosodimethylamine (NDMA) is a probable human carcinogen with a California drinking water notification level of 10 ng/L. In response to growing scrutiny of NDMA impacts, wastewater utilities that are practicing water reuse may need to evaluate NDMA sources, formation, removal and advanced treatment processes specific to NDMA in order to reliably and cost-effectively reduce concentrations in the final product water. The three-year project investigates the formation and removal of NDMA and NDMA precursors during wastewater treatment at facilities where indirect potable reuse is practiced.
