This Guide for Small Community Water Suppliers and Local Health Officials is one of a series produced by the International Water Association9s (IWA) Specialist Group on Metals and Related Substances in Drinking Water. It is an abbreviated compilation of the wide range of scientific, engineering, health and operational issues concerned with the control of lead in drinking water in small water supply systems. The IWA Specialist Group is supported by members from 26 European countries, Canada and t...

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 mate...

This Best Practice Guide on the Control of Iron and Manganese in Water Supply is one of a series produced by the International Water Association's Specialist Group on Metals and Related Substances in Drinking Water. Iron and manganese are often found in soft upland water sources associated with natural organic matter and are also commonly found in the groundwaters abstracted from confined and unconfined aquifers. The presence of iron and manganese in water is one of the most frequent reasons for...

At the zonal scale (e.g. a city or town), random daytime (RDT) sampling succeeded in demonstrating both the need for corrective action and the benefits of optimised orthophosphate dosing for plumbosolvency control, despite initial concerns about sampling reproducibility. Stagnation sampling techniques were found to be less successful. Optimised treatment measures to minimise lead in drinking water, comprising orthophosphate at an optimum dose and at an appropriate pH, have succeeded in raising c...

This Code of Practice is concerned with metal pick-up by drinking water within the water supply chain, particularly from water mains and from domestic and institutional pipe-work systems. The principal metals of interest are copper, iron, and lead, and to a lesser extent nickel and zinc. The emphasis is on cold drinking water at its point of use by consumers. Metals arising from water sources and hot water systems are not considered. The intention is that this Code of Practice establishes an int...

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 pa...

Computational modelling methods have been used to predict the risks from lead in drinking water across a simulated supply zone, for a range of plumbosolvency conditions and a range of extents of occurrence of houses having a lead pipe, on the basis of five risk benchmarking methods. For the worst case modelled (very high plumbosolvency and 90% houses with a lead pipe) the percentage of houses at risk in the simulated zone ranged from 34.1 to 73.3%. In contrast, for a simulated phosphate-treated ...

Risk-based management approaches for safeguarding the quality of public water supply, as strongly endorsed by the World Health Organisation and the Drinking Water Inspectorate, place greater emphasis on the importance of water compa- nies knowing their catchments and their associated risks. Because of their often vast extent, and problems relating to access, it has always been a challenge for water companies to gather reliable data relating to catchment landuse and to monitor catchment activitie...

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...
