What was the main purpose of the Superfund program initiated by CERCLA?

The main purpose of the Superfund program initiated by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is indeed to address abandoned or hazardous waste sites. This legislation was enacted in 1980 in response to growing concerns over hazardous waste sites that posed risks to public health and the environment.

Under the Superfund program, the federal government has the authority to clean up sites contaminated with hazardous substances and to hold responsible parties accountable for their cleanup costs. The program identifies sites that require immediate attention to prevent further contamination and harm to communities. It establishes a priority system for cleanups based on the level of threat they pose.

The other answer choices relate to concepts not directly associated with the main goals of the Superfund program. Affordable housing projects, real estate market regulation, and tax breaks for development do not align with the primary focus of addressing environmental hazards and remediating toxic sites. By concentrating on these contaminated areas, the Superfund program aims to restore safe conditions for communities and ecosystems.
