Nitrosodimethylamine (NDMA) is an emerging contaminant that, when present, poses healthconcerns for humans at very low levels and thus should be considered when developing treatmentstrategies for new water treatment, reclamation, and wastewater treatment facilities. There areother emerging contaminants, such as 1,4 Dioxane that also cause concern in groundwaterrecharge applications. Currently, the most reliable means of removing NDMA and other organiccontaminants from recycled water is with ultraviolet (UV) photolysis. Although UV treatmenthas proven to be effective in pilot testing of many small systems, a full-scale system has yet to beplaced in operation for a municipal recycled water system. This paper addresses the steps takento implement this maturing technology into the Alamitos Barrier Recycled Water Project,including a discussion of the design criteria, performance evaluation criteria, and enforcementconsiderations. Includes 2 references, figures.
