The importance of clean, uncontaminated groundwater is fundamental. About 35 per cent of the UK's drinking water supply comes from groundwater, with certain areas being heavily dependent on groundwater supplies for domestic, industrial, commercial and agricultural use. In response to mounting concern about the effect of pollution on groundwater resources, new national and European legislation is imposing greater penalties for pollution on the polluter. Although groundwater is easily contaminated it is difficult to treat or control. This book is a state-of-the-art review of pump-and-treat and other hydraulic systems for remediating contaminated groundwater. It presents good practice in the investigation, monitoring, design, specification, implementation and operation of these methods for the containment or treatment of liquid-phase contamination. Illustrated with many examples and case studies drawn from UK, European and US experience, and containing more than 260 diagrams and photographs, the book is a major work on this important subject.
