The Year in Review: Loudoun’s Superfund Dump Site Headed for Cleanup

A decades-old environmental headache near Broad Run Farms is finally headed for cleanup.

In May, the Environmental Protection Agency and the owners of the 25-acre Hidden Lane landfill reached an agreement to pay for cleanup.

The landfill opened in 1971, closing in 1985. In 1989, concerns about its contamination of groundwater were confirmed when a common degreaser was found in the water supply at nearby homes.

In 2008, the EPA designated the 150-acre area a Superfund site, placing it among the most contaminated sites in the country.

An agreement filed in Federal District Court creates a mechanism for the landowners to repay the still unknown cost of the cleanup and sets the stage for the eventual development of the land.
