The Aqualine database provides comprehensive focus on trade, technical and scientific literature concerning all aspects of water resources. Major subjects of coverage include water resources and supplies management, water legislation, water quality, potable water distribution, wastewater collection, water treatment technologies, wastewater and sewage treatment, and ecological and environmental effects of water pollution. Articles on these topics are drawn from a source list of approximately 300 journals as well as from conference proceedings, scientific reports, books and theses. Each entry includes bibliographic citation, abstract, geographic index terms and subject index terms. Beginning June 2004, Aqualine is being indexed with the Water Resources Thesaurus. Some terms from the controlled vocabulary of Aqualine were added to the Water Resources Thesaurus. The thesaurus is available as an online search tool. Previously published by the well-known and respected WRc in England, Aqualine is now produced in joint cooperation with WRc and ProQuest.
