Abstract The Unregulated Contaminant Monitoring (UCM) program (Rounds 1 and 2) and the National Inorganics and Radionuclides Survey (NIRS) were important sources of data considered by the United States Environmental Protection Agency (EPA) when evaluating the occurrence of unregulated contaminants on the second Contaminant Candidate List (CCL 2). This report presents EPAs analysis of national occurrence of CCL 2 contaminants with data from those sources. Detailed occurrence analyses are presented in this report to support the EPA regulatory determinations for the four CCL 2 contaminants with Round 1, Round 2 and NIRS data: boron, metolachlor, 1,3-dichloropropene, and 1,1,2,2-tetrachloroethane. Detailed descriptions are presented of the data sources, data editing and management, development of national cross-sections using UCM Round 1 and Round 2 data from States, and the analytical approaches used to assess the occurrence data.
