Background

The Bush Valley Landfill Site is located in Harford County, Maryland, one mile from the town of Abingdon. The site is located on a 29-acre parcel of land, approximately 16 acres of which are occupied by the landfill. The landfill stopped operating in 1983. On March 31, 1989, EPA added the Site to the Superfund program's National Priorities List (NPL). The Bush Declaration Natural Resources Management Area, a 120-acre tidal cattail marsh, borders the Site to the north and east.

What Has Been Done to Clean Up the Site?

The site is being addressed through federal, state and PRP actions.The landfill cover, institutional controls, and fencing prevent exposure to landfill waste; institutional controls prevent exposure to contaminated groundwater; and the landfill gas management system controls landfill gas.

Every five years, EPA evaluates the effectiveness of the remedy in a Five-Year Review report. The most recent Five-Year Review was completed in 2015 and may be found here.

What Is the Current Site Status?

  • The site’s long-term remedy includes landfill capping and post-construction monitoring.
  • EPA selected monitored natural attenuation for the groundwater contamination.
  • After monitoring found the cap's passive gas venting system would not reduce levels of underground landfill gas to acceptable levels, the site’s potentially responsible parties (PRPs) modified the gas management system to include active gas venting.
  • When combined with environmental monitoring and land use restrictions, the cap and gas management system will be protective of human health and the environment.
  • The cap has been seeded with warm-season grasses and native wildflowers.
  • This area will remain a green space and wildlife habitat. The landfill will also serve as a buffer between developed areas and the neighboring Bush Declaration Natural Resources Management Area.

The most current Five-Year Review Report was completed in 2015.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup.

For more background, see Institutional Controls.

Land use restrictions are in place where landfill contents remain to prohibit: (1) use of the groundwater for domestic purposes; and (2) any activity that would interfere with the integrity of the remedy.

Green Remediation

Combined with environmental monitoring and land-use restrictions, the cap and gas management system will protect human health and the environment. The cap was seeded with warm-season grasses and native wildflowers. This area will remain a green space and wildlife habitat. The landfill will also serve as a buffer between developed areas and the neighboring Bush Declaration Natural Resources Management Area.
