Soil decontamination
 The top layers of soil contaminated with halogenated organic chemicals are remediated by initial heating at moderate temperature and reduced pressure to remove soil moisture and volatile contaminants and subsequently heating the soil of minimum clay content or acidity at higher temperature, thereby decomposing the halogenated organic chemicals contained therein. Means for effecting such remediation is provided which includes a heat source, pressure regulating means, and vapor collection and treatment means.
