Beschreibung
Zusammenfassung:	A method of removing volatile chlorinated hydrocarbon base materials contained in soil is provided wherein an inorganic compound that is an oxide of an alkali metal or an alkaline earth metal or a sulfate of an alkaline earth metal, which undergoes an exothermic reaction with water, is mixed in powder or granular form with soil containing a water content of 10% to 30% by weight and volatile chlorinated hydrocarbon base material having a normal boiling point in the range of about 60 DEG to about 120 DEG C., the inorganic compound being mixed with the soil in an amount of 0.01 to 0.5 times the weight of the water content.
