According to the US federal government’s Superfund program, superfund sites are the nation’s worst toxic waste areas that are scheduled for or are currently undergoing environmental clean-up. These superfund sites are enumerated on the National Priorities List (NPL). It is estimated that 11 million US residents–including about 4 million children–live within 1 mile of a federal superfund site. These residents face serious health risks. Examples of superfund sites include the Love Canal in New York and the Wells G&H Site in Massachusetts. These sites have figured in civil action suits which have brought higher public attention to the serious environmental issue of health hazards brought on by land contamination and pollution.
