Water Pollution is a subject of growing concern in our industrial world. The environmental problems caused by the increase of pollutant loads dis charged into natural water systems have led the scientific community to pursue studies capable of relating the pollutant discharge with changes in the water quality. The results of these studies are permitting industries to employ more efficient methods of controlling and treating the waste loads, and water authorities to enforce more strict legislation regarding this matter. The present book contains edited versions of the papers presented at the First International Conference on Water Pollution (Modelling, Measuring and Prediction), held in Southampton, England, in September 1991. Its contents, which reflect the interdisciplinarity of the subject, are divided into four parts, each consisting of a keynote address and several invited and contributed papers: 1. Mathematical models (Keynote speaker: Prof. R.A. Falconer, Univer sity of Bradford, USA) 2. Data acquisition/monitoring/measurement (Keynote speaker: Dr. A. Plata Bedmar, IAEA, Austria) 3. Waste disposal and wastewater treatment (Keynote speaker: Prof. D.R.F. Harleman, MIT, USA) 4. Chemical and biological problems (Keynote speaker: Dr. E.I. Hamil ton, Environmental consultant, UK) Although the papers have been typographically edited they have been re produced directly from material submitted by the authors, and their content is a reflection of the authors' research and opinion.

The proceedings of the fifth in a series of conferences, this text's contents reflect the interdisciplinary nature of the problem of water pollution, including papers on physical processes, chemical and biological processes, mathematical modelling and data acquisition.

Engineers and scientists working in this field must be familiar with a wide range of issues and, in view of the scarcity of available data, it is important that experiences are shared. This book, which features papers from the Seventh International Conference on Water Pollution, helps to bridge the gap. Topics discussed include: groundwater and aquifer contamination; wastewater treatment and re-use of water; lakes, rivers and wetlands; coastal areas and seas; biological effects; organic contaminants; agricultural pollution; oil spills; mathematical and physical modelling; experimental and laboratory work; surveying techniques, monitoring and remote sensing; remediation studies; and health, social and economic problems.

Engineers and scientists working in the field of water pollution must be familiar with a wide range of issues including the physical processes of mixing and dilution, chemical and biological processes, mathematical modelling, data acquisition and measurement. Available data is scarce and it is therefore essential that there is a continuous exchange of information between specialists from different countries. Bringing together the latest research in this area, this volume contains the proceedings of the Sixth International Conference on Water Pollution. Over fifty papers are included and these cover topics such as: Groundwater and Aquifer Contamination; Wastewater Treatment; Lakes, Rivers and Wetlands; Coastal Areas and Seas; Biological Effects; Organic Contaminants; Agricultural Pollution; Oil Spills; Mathematical and Physical Modelling; and Experimental and Laboratory Work.
