The principle objective of the current program is to define and evaluate the waste management techniques and policies currently used for a specified set of hazardous wastes. Waste management techniques which will be evaluated include those for storage, handling, transport, neutralization, detoxification, reuse, and disposal. Other aspects of the program include description of possible new techniques for management of hazardous wastes, proof-of-principal experimentation to determine the effectiveness of techniques for which insufficient data is available for adequate evaluation, and planning of research programs necessary for developing new procedures and processes for treating hazardous wastes for which adequate techniques do not currently exist. The seventh monthly technical report summarizes the work performed by TRW for EPA from July 1, 1972 to July 31, 1972. The specific areas addressed were: (1) treatment process reports; (2) profile reports; and (3) determination of the forms and quantities of hazardous wastes.
