I-66 Closed Landfill


  • Originally opened in 1962; closed in 1982. Facility size: approximately 110 acres; Total waste accepted: 5 million tons.

  • It is the highest point in Fairfax County (Elevation 566.9 ft.).

  • Ground water monitoring and methane extraction wells are located around the perimeter of the closed landfill. Approximately 700 cubic feet per minute of landfill gas is generated.  During heating season 200 cubic feet per minute is captured and used to heat nearby maintenance facilities, with unused gas flared to control odor and migration of the gas off site.

  • The closed landfill also has an athletic field built on its premises.

  • Also known respectfully as Mt. Murtaugh. The site was named in honor of County Engineer, Hugh Murtaugh, who worked diligently to site, develop and monitor the facility from concept to closure.

  • The site continues to serve Fairfax County as a Recycling and Disposal Center.
