The Sauer Dump Superfund Site is located in Dundalk, Baltimore County, Maryland on a partially wooded lot, including wetlands and shoreline along the Back River. The property was an unpermitted facility used as a salvage yard, a dump and a landfill. The improper storage and disposal of hazardous substances has contaminated soil and sediment. On March 13, 2012, EPA added the site on the Superfund program's National Priorities List.

What Has Been Done to Clean Up the Site?

The site is being addressed through federal and Potentially Responsible Party (PRP) actions.

A Remedial Investigation and Feasibility Study (RI/FS) began in Fall 2013 and are being conducted by the PRP Group with EPA oversight. The RI will address data gaps from earlier investigations and determine the extent of contamination on and off site. The FS will then evaluate the cleanup alternatives available to address the contamination that presents an unacceptable risk to human health and the environment.

What Is the Current Site Status?

The Remedial Investigation/Feasibility Study (RI/FS) is ongoing. The RI work has included taking soil, sediment, groundwater and surface water samples on the Sauer Dump property and surrounding properties. There was also a well installed on an adjacent property to test groundwater quality.

A removal action was conducted in December 2016 on several site properties to remove soil contaminated with lead and poly-chlorinated biphenyls (PCBs) that exceeded EPA’s screening levels. EPA is working with the PRP Group to conduct additional sampling to determine if further removal actions need to be taken.

Once the RI/FS is completed, EPA will propose the preferred cleanup plan to the public for comment and hold a public meeting to present the proposed plan.

Emergency Response and Removal

Cleanup has also included removal actions, or short-term cleanups, to address immediate threats to human health and the environment. Actions in 2005 included placement of a fence around the site to restrict access, installation of a temporary cover system over contaminated areas to mitigate erosion of surface soil, and protection of the shoreline from erosion.
