An apparatus (U) is shown in FIGS. 11-13 that includes a power operated vehicle (V) that supports a vertically movable frame (W) that has a confined space defining shroud (X) on the lower end thereof that may be placed in sealing contact with the upper surface of a hazardous waste impoundment (Y) at a first station to permit the insitu detoxification of a desired portion of the impoundment. At least one power driven blade (Z) is rotated downwardly from within the shroud (X) into the impoundment to form a vertically extending zone (A-1) of particled material that is treated with a detoxifying agent that may be chemical, biological or heat from one or more plasma torches. Gases emitted during the formation of the particled zone (A-1) are subjected to scrub action by a liquid within shroud (X) and the liquid returned to zone (A-1). After the detoxification of a zone has been completed the apparatus (U) is moved to a succession of overlapping second stations where the above described method is repeated. The detoxified zones at the option of the user may encompass the entire impoundment, be in a configuration of a barrier that surrounds the impoundment, or a liner that extends downwardly around the periphery of the impoundment and thereunder.

Apparatus for in situ treatment of a hazardous waste disposal site having hazardous waste randomly distributed therein comprising: a. a plurality of cutter-injectors, each of which when rotated and moved downwardly through hazardous waste to be treated transforms a vertically extending zone thereof

Apparatus for in situ treatment of a hazardous waste disposal site having hazardous waste randomly distributed therein comprising: a. a plurality of cutter-injectors, each of which when rotated and moved downwardly through hazardous waste to be treated transforms a vertically extending zone thereof into a substantially homogenous consistency; b. means for supporting said cutter-injectors for rotation and for vertical movement thereof into and out of the hazardous waste to be treated; c. cutter drive means for rotating said cutter-injectors and for powered movement thereof into and out of the waste; d. means for sampling the toxic materials in said zone to determine the identity thereof; e. means for injecting a treatment fluid selected to treat the sampled hazardous waste into said zone through said cutter-injectors; f. means for collecting toxic gases and vapors from said zone at the surface of said zone and for sealingly engaging the surface of said zone to prevent escape of said gases and vapors to atmosphere; and g. means for separating toxic components from said collected toxic gases and vapors.
