What are "brownfield sites"?

Brownfield sites are described as previously developed locations that may be contaminated and require assessment and cleanup before they can be reused. These sites often result from industrial, commercial, or residential activities that have left behind hazardous substances or pollutants, which can include chemicals, heavy metals, or other toxic materials.

The significance of identifying brownfield sites lies in their potential for redevelopment, which can revitalize communities, promote economic growth, and address environmental concerns. By reclaiming these areas, cities can reduce urban sprawl, enhance property values, and improve public health while simultaneously managing land use more effectively.

In contrast, landfills that are fully restored do not fit the definition of brownfield sites, as they are designed specifically for waste disposal and typically undergo a different process focused on waste management and remediation. Untouched natural reserves and areas with no environmental concerns imply an absence of previous development or contamination, which is fundamentally different from the condition of brownfield sites.
