Abstract: Land treatment is one of several available alternatives to the use of landfills and surface impoundments for the treatment and disposal of hazardous waste. Using this technique, hazardous constituents can be broken down or immobilized in a treatment zone consisting of two to five feet of topsoil. Already widely used among oil refineries, the technique could be successfully applied to a much greater amount and variety of wastes, provided that the process is carefully managed. This article describes the design and operating principles for land treatment facilities, failure mechanisms, waste compatibility, climatic requirements, applicable EPA regulations, and the problems with enforcement of current federal standards governing existing sites.
