Summary:
To determine if a soil, in which toxic compounds are present, is a RCRA
hazardous waste, the origin of the toxicants must be known. If the exact origin
of the toxicants is unknown, the soil is not considered RCRA hazardous unless
it exhibits one or more of the characteristics of RCRA hazardous waste.
