摘要

The New Castle site, located in the City of New Castle, New Castle County, Delaware, is an inactive landfill that had received foundry wastes containing metals. The site is of potential health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse health effects. Contaminants released from the site have entered groundwater, soils, sediments, and surface waters. Frequent or prolonged exposure to contaminants in marsh surface water and sediments or in consumable aquatic biota would increase the risk of adverse health effects. However, frequent or prolonged exposures are unlikely in this marsh setting. Therefore, it is not expected that adverse health effects would actually occur. The proposed cap should effectively minimize the potential for airborne contaminant releases on-site and for direct contact with contaminants on-site, and should reduce releases to groundwater and surface water. However, the on-site remediation will not reduce the existing contaminant concentrations in marsh sediments.
