HazardHub Brownfield/Superfund

A brownfield is a property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. It is estimated that there are more than 450,000 brownfields in the United States. 1 They have the potential to affect property values and potentially involve extensive and disruptive remediation.

Federally designated superfund sites are generally larger and more contaminated than brownfields. Contaminants include asbestos, dioxin, lead (Pb), radiation, and soil bioavailability. 2

The HazardHub Brownfield/Superfund Risk file consists of 500 foot buffers around known brownfield sites and 2,500 foot buffers around known superfund sites. Figure 1 shows sites and buffers for a portion of the St. Louis Metropolitan Area.
