MUNCH, J. W. AND M. BASSETT. METHOD DEVELOPMENT FOR THE ANALYSIS OF N-NITROSODIMETHYLAMINE AND OTHER N-NITROSAMINES IN DRINKING WATER AT LOW NANOGRAM/LITER CONCENTRATIONS USING SOLID PHASE EXTRACTION AND GAS CHROMATOGRAPHY WITH CHEMICAL IONIZATION TANDEM MASS SPECTROMETRY. JOURNAL OF AOAC INTERNATIONAL. AOAC International, Gaithersburg, MD, 89(2):486-497, (2006).
Impact/Purpose:
To develop an analytical method suitable for monitoring NDMA at ng/L concentrations in drinking water by the end of FY05. Ideally, the method should be simple and rugged enough to be applicable to compliance monitoring in the event that NDMA becomes a regulated contaminant under the Safe Drinking Water Act (SDWA). At a minimum the method must be suitable for gathering nationwide occurrence data that can be used in the regulatory decision making process.
Description:
N-Nitrosodimethylamine (NDMA) is a probable human carcinogen that has been identified as a drinking water contaminant of concern. United States Environmental Protection Agency (USEPA) Method 521 has been developed for the analysis of NDMA and six additional N-nitrosamines in drinking water at low ng/L concentrations.
