| Abstract |
The 39-acre Dixie Caverns County Landfill is a former municipal landfill in Roanoke County, Virginia. The surrounding land is rural, with the nearest residence located 1/2 mile from the site. Two unnamed headwater streams receive surface runoff from the site, and discharge to the Roanoke River, which is located 2 miles south/southeast. The landfill is currently owned and was operated by the county of Roanoke from 1965 until its closure in 1976. In 1987, the County developed a removal work plan proposing a proprietary stabilization process to treat the flyash, and the plan was approved in 1988 with remediation levels set by EPA. At that time, EPA recommended suspension of further removal activity pertaining to the flyash because of uncertainty as to whether or not the County's plan would meet Federal and State requirements. The Record of Decision (ROD) addresses the flyash at the site as Operable Unit 1 (OU1). Future RODs will address other remedial actions based on RI/FS investigations. The primary contaminants of concern affecting the debris are metals including lead, cadmium, and zinc. The selected remedial action for the interim remedy is included. |
