Contaminated Land Liability and the Defenses to It
Four classes of person are liable for response costs at a contaminated site: the current owner or operator, the owner or operator at the time of disposal, a person who arranged for disposal or treatment, and a transporter who selected the site. Liability is strict, retroactive and often joint and several. The statute supplies only three defenses, and the practical protections for purchasers and neighbors require pre-acquisition inquiry plus continuing obligations.
