Final answer:
The liability for contamination does not solely lie with the site owner; generators, operators, and transporters can also be held accountable under RCRA and CERCLA (Superfund). Therefore given statement is false.
Step-by-step explanation:
The statement that the liability for contamination always lies solely with the owner of the hazardous waste site, and that operators, generators of the hazardous substance, and those who arranged for the disposal of the hazardous substance are not held accountable, is false. Under the Resource Conservation and Recovery Act (RCRA), hazardous waste generators are responsible for determining if their waste is hazardous and overseeing its proper disposal. Similarly, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, can also hold generators and transporters liable for contamination, so the responsibility does not rest solely on the site owner.
