Brownfields are properties, typically former industrial or commercial sites, that may be contaminated by hazardous substances, pollutants, or contaminants. These sites differ from stigmatized properties, as the primary focus is on environmental cleanup and redevelopment to make them safe and useful once more.
Historical Context
The term “brownfield” emerged as part of environmental policy lexicon in the 1990s. Historically, many urban and industrial areas have been abandoned or underutilized due to the presence of hazardous materials, making redevelopment risky and costly.
Types of Brownfields
- Industrial Sites: Former factories, mills, and processing plants.
- Commercial Properties: Closed gas stations, dry cleaners, and warehouses.
- Urban Lots: Abandoned lots in cities with historical industrial use.
Key Events
- 1995: The U.S. Environmental Protection Agency (EPA) launches the Brownfields Program.
- 2002: The Small Business Liability Relief and Brownfields Revitalization Act is enacted, encouraging the assessment and cleanup of brownfields.

Related Terms
- Superfund Sites: Contaminated sites listed by the EPA for cleanup.
- Greenfields: Undeveloped land that has never been used for industrial purposes.
- Urban Blight: Areas suffering from neglect, decay, or hazardous conditions.
Comparisons
- Brownfields vs. Greenfields: Brownfields involve cleanup and reuse of previously contaminated sites, while greenfields are pristine lands without prior industrial use.
- Brownfields vs. Superfund Sites: Brownfields are generally less contaminated and more focused on redevelopment, whereas Superfund sites are highly toxic and prioritized for extensive cleanup by the EPA.
Interesting Facts
