Answer:
Superfund
Explanation:
Due to inappropriate disposal and management of hazardous substances and sites, The united state environmental protection agency (EPA) established the Superfund program.
The Superfund is a fund that is set aside by the United State government to clean up of a site that is contaminated by hazardous substances. The Superfund can only be used when the polluter of the hazardous site is unknown. The polluter of the site either re-mediate the contaminated site or pay for the remediation of the contaminated site to be carried out by the EPA.
The United State has a total of one thousand and three Superfund sites with Pennsylvania, New Jersey and California accounting for the highest number of Superfund sites.
