The Franklin Institute Research Laboratories, Science Information Services Department prepared for the Environmental Protection Agency, Volume 4 of a monthly current-awareness abstracting bulletin, Municipal Technology Bulletin, which dealt with methods of municipal waste water treatment, problems of water quality, and water pollution control. Volume 4 of the Bulletin contained abstracts of technologically significant literature appearing in print between May - October 1976. Under the same grant, the Science Information Services Department provided abstracts, including those appearing in Volume 4, to the Water Resources Scientific Information Center (WRSIC) as a center of competence on municipal waste water for WRSIC. Topics covered in the Bulletin and in the WRSIC input include: analytical techniques for water quality measurements; biological, chemical, and physical methods of waste water treatment; construction and equipment for pollution control; mathematical, statistical, and simulation model studies; storm runoff, tunnelling technology and sewer systems; and, treatment plant operation and automation. This report is a compilation of the abstracts arranged in chronological order by accession number within subject categories.
