East Harbor
Sediments in areas of Eagle Harbor are contaminated with polynuclear aromatic hydrocarbons (PAHs) and other organic compounds, as well as with metals, primarily mercury. EPA's Remedial Investigation (RI) of sediment contamination in Eagle Harbor initially addressed the harbor as a single unit concurrent with enforcement activities at the Wyckoff Facility. After completion of the Eagle Harbor Feasibility Study (FS) in November 1991, EPA proposed the administrative separation of the Harbor into East Harbor and West Harbor operable units.
After completion of the RI/FS, EPA proposed initial cleanup actions in the East Harbor operable unit. The proposed cleanup was a clean sediment cap over heavily contaminated sediments in the East Harbor. EPA documented its decision to complete the cap under CERCLA removal authorities in an Action Memorandum (June 1993). In 1993 and 1994, EPA placed clean sediments over a 54-acre hotspot area as part of a non-time-critical removal action. The September 1994 ROD called for monitoring and maintaining the existing sediment cap and capping remaining subtidal areas of concern, monitoring the success of natural recovery in intertidal areas, enhancing existing institutional controls to reduce public exposure to contaminated fish and shellfish, and demolishing in-water structures.
