Water Science and Technology publishes peer-reviewed papers on all aspects of the science and technology of wastewater treatment and water quality management worldwide. This encompasses five broad areas: • Wastewater treatment and transportation processes for stormwater and domestic, industrial and municipal effluents • Sources of pollution including hazardous wastes and source control • Effects and impacts of pollution on rivers, lakes, groundwater and marine waters • Water reuse and aquatic environmental restoration • Policy, strategy, control and management aspects of water quality Water Science and Technology, together with Water Science and Technology: Water Supply and Water Practice and Technology, have a special mission to serve as a bridge between science, engineering applications and management aspects of water as represented by the many IWA Specialist Groups. Papers describing progress in full-scale implementations are particularly encouraged. Water Science and Technology offers fast publication for new findings and research directions.
