Superfund Site: HIDDEN LANE LANDFILL, Sterling, VA
Superfund Site Profile
The Hidden Lane Landfill was a 25-acre privately owned and operated disposal facility north of Virginia Route 7 between the Broad Run Farms and Countryside communities. It is immediately adjacent to the floodplain of the Potomac River. Starting in 1971 the facility accepted a variety of solid wastes including construction and demolition wastes, land clearing wastes and other items such as appliances, tires, paper, and cardboard. The county closed down the facility in 1984, pursuant to a local court decision the year before. The Hidden Lane Landfill had been named by county and state health officials as the likely source of the degreasing solvent trichloroethylene, first detected in drinking water wells of some homes in the Broad Run Farms subdivision just west of the landfill in 1989. . Hidden Lane Landfill was listed on the National Priorities List in March 2008.
TOPICS IN FOCUS
In 2015, EPA completed indoor vapor intrusion (VI) testing at 18 properties near the Hidden Lane Landfill Site. The purpose of the testing was to determine if vapors from the contaminated groundwater plume were getting inside homes.
The results of the tests show that no vapors from the groundwater are entering the homes at this time. Additional testing may be needed in the future to ensure that indoor air continues to be protective of human health.
