A waste which, when using the toxicity characteristic leaching procedure, leaches any number of metallic, organic, or pesticide constituents in concentrations greater than specified in the regulation.  Examples for these constituents include arsenic, barium, cadmium, chloroform, chromium, m-cresol, mercury, selenium and silver. 

A solid waste that exhibits the characteristic of toxicity has the EPA Hazardous Waste Number specified in Table I which corresponds to the toxic contaminant causing it to be hazardous.
