Background

The 67-acre Suffolk City Landfill site is located in Suffolk, Virginia. A sanitary landfill began operating at the site in 1967. The landfill accepted municipal solid waste, pesticides and chemical waste. Landfill operations ended in 1985 when a regional landfill became operational. The City designed a closure plan, which was submitted to the State. The city covered, graded, and replanted the landfill in 1988.

Waste disposal activities contaminated soil and groundwater. After initial actions, EPA determined that the site required no further cleanup. EPA took the site off the Superfund program’s National Priorities List (NPL) in 1995. Landfill gas monitoring and groundwater sampling are ongoing.

What Is Being Done to Clean Up the Site?

As part of a legal agreement, the City of Suffolk installed a leachate collection and treatment system at the Site. Under orders from the State, the City of Suffolk agreed to conduct an intensive study of soil and ground water contamination at the site to determine its nature and extent and to recommend strategies for its cleanup. The study, completed in 1992, showed that pesticide contamination no longer exists at the site. Scientific information on pesticides has shown that these substances are prone to degrading naturally over time. Therefore, no other actions are required at the site; the area is safe and no other action is needed. EPA has deleted the site from the National Priorities List.

What Is the Current Site Status?

In 1988, the City of Suffolk covered, graded and replanted the landfill. The city also installed a leachate collection and treatment system and conducted a study of soil and groundwater contamination. The study, completed in 1992, showed that contamination no longer existed at the site.  The arsenic in groundwater was found to be naturally occurring.

The site’s long-term remedy included a decision that the site required no further actions based on previous cleanup activities. Landfill gas monitoring and groundwater sampling are ongoing. The City of Suffolk monitors landfill gas and collects groundwater samples from the Site. EPA has deleted the site from the National Priorities List.

Operable Units

During cleanup, a site can be divided into a number of distinct areas depending on its complexity. These areas, called operable units (OUs), may address geographic areas, specific problems, or areas where a specific action is required. Examples of typical operable units include construction of a groundwater pump and treatment system or construction of a cap over a landfill.
