EPA Announces the First National Database on Contaminants, Water Sources is Now Available
Daily Environment Report,
August 9, 1999, pA-1.

The Environmental Protection Agency announced on August 5, 1999 that the first national database on both regulated and unregulated contaminants in public drinking water is now available. The agency stated that the National Contaminant Occurrence Database (NCOD) is designed to support EPA decisions on regulating contaminants and, as a part of its right-to-know initiative, will provide the public with heretofore inaccessible data on contaminants in their water and the sources of that water.

The information will be used extensively for public health and scientific purposes. However, the agency warned the public to use this information "cautiously, since many of the contaminants occur below health effect or regulatory levels or are rarely found." The EPA was required by the Safe Drinking Water Act Amendments of 1996 to make such a database available by August 6.

The databases contain information from public water systems, the U.S. Geological Survey National Water System (SDWA) on physical, chemical, microbial, and radiological contaminants as well as other sources. Since the NCOD does not analyze data, the EPA has said that more useful information on the quality of water may be obtained from "consumer confidence reports." SWDA requires water utilities to send customers annual reports on the quality of their water beginning in October.
