A treatability study is a study in whicha hazardous waste is subjected to a physical, chemical, biological or thermal treatment process to determine:

• Whether the waste is amendable to the treatment process

• What pretreatment is required

• The optimal process conditions needed to achieve the desired treatment

• The efficiency of a treatment process for a specific waste of wastes

• The volumes and characteristics of residuals resulting from various treatment processes.

This definition also includes linear compatibility, corrosion and other material compatibility studies as well as toxicological and health effect studies.

Treatability is not a means to commercially treat or dispose of hazardous wastes.

Treatability studies cannot involve the placement of hazardous waste on the land or the open burning of such waste.
