What are properties called by the EPA if they contain hazardous waste?

The correct term for properties that contain hazardous waste, as designated by the Environmental Protection Agency (EPA), is "Superfund Sites." This designation applies specifically to locations that have been identified as contaminated by hazardous substances and are prioritized for cleanup due to the potential risks they pose to human health and the environment. The Superfund program was established to address these hazardous waste sites and ensure proper remediation efforts are conducted.

The other terms mentioned do not specifically capture the legal and programmatic nuances associated with the EPA's designation. For instance, while "Contaminated Sites" and "Polluted Areas" suggest a problem with hazardous materials, they do not encompass the broader legal framework and cleanup responsibilities established under the Superfund law. "Hazardous Waste Facilities" typically refers to locations that are actively involved in the treatment, storage, or disposal of hazardous wastes, rather than sites identified for cleanup due to contamination. Thus, "Superfund Sites" accurately reflects the specific classification used in environmental law for areas that require federal intervention for remediation due to hazardous waste.
