Book excerpt: Based on proven investigation into cleanup techniques, the material in this manual gives engineers a working knowledge of the field and a basis for making key decisions during the cleanup process. It is easy to get petroleum into the ground, but hard to get it back out again. The problem does not exist in the groundwater or the soil alone, but in a dynamic balance between the soil, water, and air in the soil. Gasoline and any of its volatile components can and do move between the soil, air and water, and they cost billions of dollars every year in contamination cleanup. This new book provides the information needed for cost- and time-effective petroleum-contaminated site cleanup. Originally developed as an oil company's training aid, this book discusses the hows and whys of site cleanup-geology, data gathering, cleanup alternatives, remediation costs, and manage-ment of consultants/contractors Plus the_book contains a criti-cal examination of the benefits and limitations of each type of remediation technology. There is never only one way to clean up a particular site. The choice of the method of cleanup is one of the greatest factors affecting the cost. Another important cost factor is the level of cleanup required to satisfy the regulatory cleanup community. This new book will not only provide a fundamental under-standing of site remediation techniques but also the knowledge to make cost-effective, environmentally-sound choices during the remediation process.
