Environmental engineers are primarily responsible for restoring hazardous waste sites to a condition where they will not cause adverse effect to human health and the environment and for creating a waste-handling architecture that prevents future industrial wastes from causing any damage. This book presents a roadmap for hazardous waste management. Beginning with the legal framework that defines what a hazardous waste is and when a waste becomes hazardous, a practicing engineer needs to have a general idea of environmental audits, toxicology, site characterization, treatment processes, and site-monitoring protocol. In addition, the toxic compounds of concern may partition into the soil, groundwater, and air. Thus, any attempt to deal with such a situation requires integration of law, science, technology, and social policy. This book guides the reader with the help of numerous solved examples with a clear goal of showing how these topics are integrated in practice.
