FORMER HERCULES INCORPORATED PROPERTY, WEST EDGEMONT DRIVE AND SOUTH RAYON DRIVE, COVINGTON, VIRGINIA
Public Notice: Voluntary Remediation Program (VRP) Activity, VDEQ VRP Case #00648, 2017
The property entered the VRP in December 2013. About 12 acres on the eastern portion of the property served as an unlined landfill for benign wastes (i.e., baled saran, latex solids) from 1965 to 1993. A soil cap installed on the landfill unit prevents rainwater infiltration and degradation. A thick vegetative cover grows over the cap as an additional source of protection against erosion. Historical environmental investigations identified localized carbon tetrachloride (CT) impacts in groundwater on the eastern portion of the property, upgradient of the landfill. Corrective action measures implemented for CT during 2010-2014 included enhanced bioremediation and groundwater monitoring. Based on effective and successful implementation of enhanced bioremediation and the supporting routine and performance monitoring data, the Virginia DEQ terminated post-closure care in April 2015 as CT concentrations declined below the Groundwater Protection Standard (or non-detect). The site characterization report submitted in March 2017 concluded that this property does not pose a risk to human health or the environment provided land use controls are implemented. A Certification of Satisfactory Completion of Remediation will be issued by Virginia DEQ upon completion of the VRP requirements. The property is being considered for future recreational use. http://www.deq.virginia.gov/Portals/0/DEQ/Land/RemediationPrograms/VoluntaryRemediationProgram/VRP00648.pdf
