CHOICE Review

Cost estimates for remediating the tens of thousands of hazardous waste sites in the US already exceed one trillion dollars, and even this figure is probably a serious underestimation. There is a critical need to develop new technologies to decontaminate the soil and groundwater at existing sites and also to prevent the accumulation of further wastes. This book, based on papers from a 1991 symposium, focuses primarily on the major components of the problem--heavy metals, radioisotopes, and organics--but it also includes some related topics, such as plastics recycling. The three main sections cover remediation technologies, methods of waste avoidance, and promising new methods currently under development. The introduction provides a general overview, but the papers are mainly research reports on specific treatment methods, and so are rather specialized. The information should, however, be very useful to advanced undergraduates, graduate students, and experienced practitioners. H. E. Pence; SUNY College at Oneonta
