Public Health Service Publication No. 956
The Standards published herein have been promulgated as Public Health Regulations in the Federal Register. As such they became effective April 5, 1962, as the Standards to which drinking water and water supply systems used by carriers and others subject to Federal quarantine regulations must conform. The Division of Environmental Engineering and Food Protection is responsible for the application of these Standards to all carrier water supplies. These Standards supersede the Public Health Service Drinking Water Standards- 1946, as amended in 1956. The new Standards were developed with the assistance of an Advisory Committee appointed by the Public Health Service to revise the Standards of 1946. The Committee in its deliberations took cognizance of man's changing environment and its effect on water supplies. Accordingly, new sections, such as one on radioactivity, have been added and substantive changes have been made elsewhere. The new Standards are in a form believed useful in evaluating the quality and safety of water supplies generally and they are hereby recommended for such use.
