It is 25 years since the discovery that potentially harmful chemical by-products are generated by the disinfection of drinking water. Since then, disinfection by-products (DBPs) have had a significant impact on drinking water standards, treatment processes and monitoring. Regulators and water suppliers must find a balance between the need to prevent microbial contamination, and the desire to control the levels of DBPs in the water we drink. Disinfection By-Products in Drinking Water: Current Issues brings together contributions from regulators, researchers and water suppliers from Europe and North America to discuss the current situation and identify the main issues associated with reaching a cost-effective balance between microbial and chemical risks. Overviews of the latest research are presented alongside case studies of practical approaches taken by water companies and regulators on both sides of the Atlantic. Contributions are grouped into sections covering: DBP formation and occurrence; advances in analysis and monitoring; standards and regulation; balancing chemical and microbial risk; and control methods for DBPs. A final chapter pulls these strands together to provide a view of the way forward. Disinfection By-Products in Drinking Water: Current Issues is a unique collection of the views of key people, and as such will be essential reading for all those with an interest in this complex problem.
