  • Improved controls would reduce superfund backlogs

    Neither EPA nor the New Jersey Department of Environmental Protection (NJDEP) took actions needed to ensure progress at seven New Jersey-led Superfund site clean-ups. These sites were listed on the NPL over 20 years ago but still have not had a final clean-up remedy constructed (construction completion). Delays occurred primarily because EPA Region 2 and New Jersey did not use available ...

  • Site Hazard, Settlement Activity and Superfund Liability Valuation

    HYPOTHESIS: Site (extent and cost of clean-up) and allocation uncertainty (number of parties associated with the site) surrounding contingent Superfund liabilities affect their market valuation. EPA data providing information on the extent of uncertainty surrounding contingent Superfund liabilities will be relevant to valuation.

  • Superfund Investigates Land Pollution from the Past…and Present

    On September 7, 2016, we took steps to respond to states, tribes and citizens who asked for our help addressing contaminated sites. In response, we are adding 10 hazardous waste sites to the National Priorities List (NPL). The NPL is our list of more than 1,300 of the most contaminated sites in the country that we are addressing under the Superfund program. Superfund is one of the most important ...

  • Building and breaking a bridge of trust in a Superfund site remediation

    Trust is widely recognised as a key variable in perceptions and decision-making about environmental risks. However, most considerations of trust treat it as a simple two-agent relationship. Based on an analysis of a contaminated site cleanup in New Jersey, we identify a more complex construction of trust formed between multiple stakeholders. We refer to this construction as 'bridging'. In the ...
