Description:
The National Contaminant Occurrence Database (NCOD) includes data used to identify contaminants on the Candidates Contaminant List (CCL). The data is used to determine whether to develop drinking water standards for a particular contaminant and to develop standards for the contaminants that the Agency selects. The information comes from a number of sources, including public water systems and source (ambient) water data. For public systems, the database holds historical data on regulated and unregulated contaminants. The data is available to the public.
The Safe Drinking Water Accession and Review System (SDWARS) serves as the input to NCOD, and is scheduled as EPA 253.
