Soil Chemistry Of Hazardous Materials

The second edition of The Soil Chemistry of Hazardous Materials has been extensively revised and updated since the first edition. The text reflects the state of the science. Much is known about some areas and very little about others. Nevertheless, there is a great deal that is misunderstood about the behavior of chemicals in soil: One of the author's principal objectives in publishing the work is to dispel commonly held misconceptions and correct misapplications; over 100 have been identified and outlined in this edition. The Soil Chemistry of Hazardous Materials is devoted to providing scientists and professionals with a basic knowledge of the principles t hat govern the proper estimation of migration and degradation potential of chemicals in topsoil, and in the saturated and unsaturated zones. These principles apply to chemical behavior in solid and hazardous waste treatment and disposal units employing or impacting soil and other geologic materials--landfarms, landfills, deep well injection systems, compost piles, and sites affected by leaks, spills, and other types of accidental or deliberate chemical releases. A substantial amount of new knowledge concerning the basic nature and properties of soil, the behavior of water in the unsaturated zone, and the behavior of bulk hydrocarbons in soils appear only in this edition. Examples include a discussion of NAPL's and how they move in the subsurface and treatment technologies such as bioremediation, metal stabilization, and permeable walls. Because the focus is on practical applications of these basic chemistry principles, the text incorporates information from other soil science and environmental disciplines where appropriate.
