Abstract
A chromium ore processing facility in Maryland was mandated by the State to undertake remedial steps to prevent further migration of contaminants to the soil, groundwater and surface water. The owner of the facility entered into a Consent Decree (CD) with the U.S. Environmental Protection Agency (EPA) and Maryland Department of the Environment (MDE) to submit and execute a remedial design based on findings of site investigations. These investigations found that the soils were contaminated with hexavalent chromium. Additionally, both the shallow and deep aquifers, and surface water were found to be contaminated with chromium. The remedial action completed at this site is designed to minimize the future releases of contaminants to the air, adjacent soils, surface water and groundwater, while allowing for potential site redevelopment. The corrective measures included: (1) installation of a new perimeter bulkhead and a deep vertical hydraulic barrier (slurry wall) as a containment structure; (2) installation and operation of a groundwater withdrawal system within the containment structure; (3) construction of a multimedia cap over the containment area; and (4) a comprehensive surface and groundwater monitoring system. In addition, the site remediation activities were conducted in a manner to prevent any significant cross-media transfer of pollutants during site preparation and installation of containment structures at the site.
