Abstract: Hurricane accelerated erosion and land loss of the Mississippi River coastal zone has necessitated a re evaluation of environmental risk at closed National Priority List (NPL) industrial waste sites in Louisiana, USA. Clean up criteria of a site were evaluated under the Louisiana Risk Evaluation Corrective Action Program (RECAP 2003). An assessment of the closed site using RECAP 2003 indicated that hexachlorobutadiene remained at concentrations greater than allowable soil saturation limits. Several Constituents of Concern (COCs) exceeded RECAP 2003 human health risk standards. The findings support the need for continued assessment and field validation of closed NPL sites in coastal environments.

Keywords: risk assessment; national priority list; remediation criteria; hazardous waste; coastal land loss; environmental risk; industrial waste sites; USA; United States; human health; health risk standards.
