Abstract
This paper aims to investigate and clarify the procedures of treatment and redevelopment process of former factory and landfill sites known as brown-fields in the United States. Investigation methods are interviews and site visits. It concludes that U.S. have two applicable laws, such as national 'Superfund' law for highly contaminated sites and state's 'Voluntary Cleanup Program VCP' for low level of contamination with more linkage to reuse the site. It also clarified that while Superfund law strictly regulates polluter's liability, VCP exempts third parties liability to encourage reuse and redevelopment by developers and buyers.
