Answer:
United Disposal, General Manufacturing Corporation, Ace Trucking Company, and/or Investment Properties.
Explanation:
When the EPA cleans up site, it generally uses money from its superfund and it is allowed to recover the money from the entity that caused the pollution (either directly or indirectly), the owner of the premise or the user of the premise. I.e. they can recover the funds from anyone involved. The EPA will try to recover the funds based on several aspects including the financial position of the entities involved. E.g. if United Disposal, Ace Trucking Company and General Manufacturing Company filed for bankruptcy, the EPA will recover the funds from Investiture Properties even if they were not responsible for the pollution.
