Determines the levels of n-nitrosodimethylamine (NDMA) in drinking water, recycled water, and wastewater through an occurrence survey of potentially vulnerable raw and treated water supplies. Establishes whether NDMA is a disinfection by-product and the possible water quality factors (i.e., precursors, pH, chlorination species, natural organic matter) affecting its formation in drinking water and wastewater treatment plants. Characterizes the fate and transport of NDMA in both surface water and groundwater in order to determine what levels of NDMA are likely to occur in groundwater given the initial concentration in treated wastewater effluent.
