Metals and Related Substances in Drinking Water comprises the proceedings of COST Action 637 - METEAU, held in Kristianstad, Sweden, October 13-15, 2010. This book collates the understanding of the various factors which control metals and related substances in drinking water with an aim to minimize environmental impacts. Metals and Related Substances in Drinking Water: Provides an overview of knowledge on metals and related substances in drinking water. Promotes good practice in controlling metals and related substances in drinking water. Helps to determining the environmental and socio-economic impacts of control measures through public participation Introduces the importance of mineral balance in drinking water especially when choosing treatment methods Shares practitioner experience. The proceedings of this international conference contain many state-of-the-art presentations by leading researchers from across the world. They are of interest to water sector practitioners, regulators, researchers and engineers.

Metals are inorganic substances that occur naturally in geological formations. Naturally occurring metals are dissolved in water when it comes into contact with rock or soil material. Some metals are essential for life and are naturally available in our food and water. Trace amounts of metals are common in water, and these are normally not harmful to your health. In fact, some metals are essential to sustain life. Calcium, magnesium, potassium, and sodium must be present for normal body functions. Cobalt, copper, iron, manganese, molybdenum, selenium, and zinc are needed. However many of the metals and metalloids that are found in drinking water can have an adverse impact on human health. This book provides a 'state-of-the-art' review of the health implications of metals and metalloids in drinking water and is a key reference in the risk assessment and management of water supplies. The increased urbanization and increased water demand in industrial areas has amplified the metals problem in groundwater sources. In fact the contamination of our water resources by poisonous metals occurs largely due to human activity. These activities include industrial processes, such as electronics industry and mining activity, agricultural activities, and the dumping of wastes in landfills. The International standard references concerning water resources are various and, though they are based on WHO guidelines, they are extremely diversified in relation to local issues and emerging problems. This report pulls the information together to provide an important reference source.

The EU Drinking Water Directive sets a range of standards for metals and related substances in drinking water, many of which are concerned with health protection. A number of these standards are very stringent and require compliance to be assessed at the point of use. Because of the difficulties associated with monitoring, historic practices in many countries have concentrated on the quality of water within the distribution network. As a result, the magnitude of problems with some metals and related substances in drinking water is not fully appreciated in all European countries, and the extent and nature of corrective actions differ widely. This Best Practice Guide on Metals Removal From Drinking Water By Treatment describes drinking water standards and regulations, and explains the impact of a range of water treatment processes on metal levels in drinking water. Its objectives are to provide a basis for assessing the extent of problems and to identify appropriate water treatment options. The Guide provides a reasoned guide to selection of key water treatment processes. Each chapter focuses on a specific water treatment process and has been written by experts in that particular process. Best Practice Guide on Metals Removal From Drinking Water By Treatment provides practice-based knowledge for water engineers and scientists in large and small water utilities, regulatory agencies, health agencies and local municipalities (from cities through to small rural communities). It also supports university level teaching in degree schemes that relate to water management. This Guide is one of a series produced by the International Water Association’s Specialist Group on Metals and Related Substances in Drinking Water. The series is an up-to-date compilation of a range of scientific, engineering, regulatory and operational issues concerned with the control and removal of metals from drinking water.

There is increasing concern regarding the presence of metals, particularly heavy metals in drinking water. In addition to the well-known toxic effects of lead, which are discussed at length in the Best Practice Guide on the Control of Lead in Drinking Water (in this series of Guides), the latest WHO guide values for maximum mean concentrations of arsenic, nickel and others in drinking water have been lowered compared to previous versions. European Union, USA and National standards for drinking water have followed the trend based largely on the same toxicological information. There is currently growing interest in the presence of hexavalent chromium in drinking water following its finding in some drinking waters in the USA above the national upper limit for total chromium and research suggesting that this limit needs to be considerably lowered. Some metals, particularly iron and manganese are associated with the production of discoloured (dirty) water in distribution systems and are therefore very important to the production of water with acceptable aesthetic qualities. Others (iron and aluminium) are key to the treatment of raw waters to drinking water standards. In most cases it is not possible to continuously monitor waters for metals and suitable sampling programmes must be designed and carried out to give results representative of the true water quality. The Best Practice Guide on Sampling and Monitoring of Metals in Drinking Water gives guidance on the design and quality control of sampling programmes for metals in Raw waters, in the water treatment works, in the drinking water distribution system and at the consumers tap. It also gives guidance on the analytical methods that can be used for the analysis of metals and quality control of those methods. Sampling programmes on the same water will vary according to the purpose for which they are carried out and the statistical techniques used to determine and design the different types of programme are outlined. Finally some case studies of optimisation of sampling are set out. Best Practice Guide on Sampling and Monitoring of Metals in Drinking Water is a valuable text for scientists, engineers and quality managers working in drinking water supply, laboratory managers and scientists who carry out sampling and analysis, and water industry consultants. It is also an excellent resource for post graduate and research workers in the field of drinking water. Editor: Dr Adam Postawa, AGH University, Krakow, Poland
