The U.S. Environmental Protection Agency's (USEPA) Office of Ground Water and
Drinking Water (OGWDW) collects national occurrence data on drinking water contaminants
using Unregulated Contaminant Monitoring Regulations (UCMRs). These contaminants may be
selected from the Drinking Water Contaminant Candidate List (CCL), or may be emerging
contaminants with the potential for inclusion on future CCLs. In order for a contaminant to be
included in a future UCMR, a standardized analytical method for its measurement in drinking
water must be available. A group of 13 chemical contaminants are being evaluated for inclusion
in a direct aqueous injection-liquid chromatography/tandem mass spectrometry (DAILC/
MS/MS) method. Preliminary data were obtained for all 13 chemical contaminants. For
chlorinated tap water fortified at 10 µg/L, recoveries ranged from 83 to 106% with a relative
standard deviation of 0.8-7.9% for 11 of the 13 chemicals. Includes 21 references, tables.
