Final answer:
The Superfund Act is designed to manage the cleanup of hazardous waste sites, with the aim of protecting public health and the environment.
Step-by-step explanation:
The role of the Superfund Act, officially known as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), in waste disposal is to address hazardous waste cleanup. The Superfund program is managed by the Environmental Protection Agency (EPA) and aims to clean up sites contaminated with hazardous substances, which are often identified on the "National Priorities List." This program plays a crucial role in ensuring that dangerous waste sites are remediated and that the health of the public and the environment are protected from the consequences of hazardous waste contamination.
