Visit: http://iwapublishing.com The Best Practice Guide on the Control of Lead in Drinking Water brings together, for the first time, all of the regulatory, health, monitoring, risk assessment, operational and technological issues relevant to the control of lead in drinking water. Its focus is Europe and North America and the Guide benefits from the input of an international research network involving 28 countries. A large range of illustrative examples and case studies are provided. The Guide will be of interest to scientists, engineers, regulators and health specialists who are involved in the provision of safe drinking water. The reader will gain a comprehensive understanding of how to assess lead in drinking water problems, both in the water supply systems that serve a City, Town or rural area and at individual properties, dependent on their knowledge of pipe-work circumstances and water quality. Options for corrective action are outlined and their strengths and weaknesses explained, with information on costs and environmental impact. The reader should then be able to develop a strategy for controlling lead in drinking water in their area, establish an appropriate monitoring programme, select the right combination of corrective measures, and define the level of risk reduction that will likely be achieved. The Best Practice Guide provides a succinct compilation of the wide range of issues that relate to lead in drinking water, at a time when the regulations are under review in both Europe and North America. It will also be very relevant to all those implementing the Protocol on Water and Health, as lead in drinking water has recently been adopted as one of the key issues requiring assessment, improvement planning and reporting. The key features are: For the first time, all the complex inter-related aspects of lead in drinking water have been brought together. The detailed explanations given on sampling and monitoring should avoid mistakes being repeated. The information on optimising corrective treatment measures is the most comprehensive to date. The Best Practice Guide will facilitate the protection of water consumers from lead contamination and reduce associated health risks. This Guide is one of a series produced by the International Water Association’s Specialist Group on Metals and Related Substances in Drinking Water. It is a state-of-the-art compilation of the range of scientific, engineering, regulatory and operational issues concerned with the control of lead in drinking water.

The management of small water supplies presents a unique challenge globally, in countries at all stages of development. A combination of lack of resources, limited understanding of the risks and poor expertise means that individuals and communities may face serious health risks from these supplies. This is not only due to microbiological contamination, but also from contamination by metals, either due to natural or man-made contamination of the source water or through leaching from plumbing materials due to inadequate conditioning and corrosion inhibition and use of inappropriate materials. This Best Practice Guide aims to share best practice and experience from around the world on a practical level. It looks at general issues relating to small supplies and ways of managing these, adopting a Water Safety Plan approach to deliver sound and lasting improvements to quality. Management techniques and treatment relating to specific metals will be covered, from a theoretical and practical perspective, to deliver a publication that will act as an authoritative guide for all those faced with the problem of ensuring the quality of a small water supply. Varied case-studies will help to illustrate issues and ways in which they have been resolved. Table of contents The Difficulties of Managing Water Quality in Small Water Supplies; What are Small Supplies?; The Management and Regulation of Small Water Supplies; The Vulnerability of Small Water Supplies to Contamination by Metals; Water Safety Plans for Small Water Supplies; Making WSPs Work for Small Supplies; Teamwork- The Value of a WSP Team; A Practical Guide to Developing a WSP for a Small Supply; Practical Guidance for Risk Assessments; Establishing the Metals Problem: Risk Assessment, Sampling and Analysis; The Range of Possible Problems; Metal Solubility and Influencing Factors; Risk Assessment of Small Water Supply Systems; Sampling and Analysis; Consumer Awareness; Sources of Metals in Small Water Supplies; Origin of Contaminants; Contamination of Surface Waters; Contamination of Ground Water; Contamination from Treatment Processes; Contamination in Distribution Pipework; Contamination from Plumbing Fittings; Water Treatment Processes Available for Use on Small Water Systems; Process Selection; Types of Treatment; Practical Considerations of Treatment for Metals in Small Water Supplies; Iron; Manganese; Conditioning of Water to Prevent Dissolution of Plumbing Materials or Post-treatment Contamination; Treatment is Only Part of the Story; Indications and Effects of Post-treatment Metal Contamination in Small Water Supplies; Establishing the Source of the Problem; Factors Controlling the Corrosion of Metals into Small Water Supplies; The Conditioning of Water to Minimise Corrosion; Manual of Individual Metals in Small Water Supplies, Aluminium, Antimony, Arsenic, Barium, Beryllium, Boron, Cadmium, Chromium, Cobalt, Copper, Iron, Lead, Manganese, Mercury, Nickel, Selenium, Tin, Tungsten, Uranium, Vanadium, Zinc; Case Studies; Arsenic removal in Small Supplies in Italy; A New Borehole Supply with Iron Removal for a Single Property in England, UK; Metals in Small Water Supplies in Areas of Water Scarcity in African Regions; Unexplained Lead Contamination of a Small Water Supply in Northern Scotland EDITORS Matt Bower, Drinking Water Quality Regulator for Scotland, UK Colin Hayes, Swansea University, UK

Part of Metals and Related Substances in Drinking Water Set - buy all five books together to save over 30%! 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
