ABSTRACT OF THE INVENTION The insitu method of detoxifying a hazardous waste impoundment to a desired degree at a first station thereon without contaminating the ambient atmosphere is carried out by an apparatus (U) that includes a power operated vehicle (V) that movably supports a frame (W) that has a confined space defining shroud (X) on the lower end thereof that is in sealing contact with the impoundment during the carrying out of the method. A power driven cutter (Z) when moved downwardly below the shroud (X) forms a vertical zone A of particled hazardous waste. Pressurized steam from a boiler (B) is discharged into zone A. Volatile toxic organic compounds in zone (A) flow upwardly into shroud (X). A blower (C) withdraws air, steam, toxic vapors and toxic gases from shroud (X) as a toxic stream and at a sufficiently rapid rate as to maintain a negative pressure within the shroud, with the stream after being freed of toxic components by a unit (P) being returned to zone A. The major portion of water soluble salts of toxic metals present in zone (A) are transformed to substantially water insoluble compounds by discharging an oxidizing agent into zone (A) by use of a pump (G). When a sensing unit (F) indicates zone (A) has been detoxified to a desired degree a feeder (H) is used to discharge a dewatering agent into zone A to transform the latter to a water impermeable mass from which toxic components remaining therein will not leach out. The above described method is carried out by apparatus (U) in succession at a number of second stations to encompass the entire impoundment, define a barrier wall therearound, or a liner thereunder.
