Area 1 Removal
Drums containing hazardous waste were buried in that section of the site known as Area 1. Those drums, and their contents, were removed from the site during an eight-month project in 2002. All of the drummed waste was transported and disposed at an off-site hazardous waste disposal facility.

If you're interested in the technical details of this project, please continue:
- From February 25 through November 15, 2002, a removal action involving the removal of subsurface hazardous waste drums and drum carcasses, drummed contents, and industrial waste was completed. The work was conducted pursuant to an EPA AOC signed by the VRAC, and dated September 10, 1998.
- Excavation, backfilling and sampling of all nondrummed material was
conducted throughout the Area 1 removal to characterize the material.
- A total of 16 grids were determined to contain TCLP TCE-impacted soil/debris
and one grid was determined to contain TCLP TCE and PCB-impacted soil/debris.
A work plan was submitted by the VRAC on December 23, 2002, describing
in-situ VE would be used to treat the 17 grids containing TCLP TCE-impacted
soil/debris.
- A total of 15,622 subsurface drums were removed by VRAC contractors
from the 50 50- by 50-foot grids and seven test trenches, identified
as removal action areas based on geophysical anomalies.
- Drums containing hazardous waste solids (containing combinations of
PCBs, ignitable waste, and/or TCLP TCE, PCE, MEK, benzene, lead, vinyl
chloride, 2,4-D, cadmium, and chloroform) accounted for 94 percent of
the total drums removed in Area 1. In addition, drums defined as RCRA
empty drums totaled approximately 5 percent. Drums containing any measurable
liquids (containing combinations of flammable liquids, PCBs, and/or
TCLP TCE, PCE, MEK, and lead) accounted for less 1 percent of the total
drums (totaling approximately 2,250 gallons collected).
- A summary of waste disposed in Area 1 includes approximately 1,522
tons of RCRA waste (ie TCLP and ignitable waste from drums and soil/debris),
137 tons of a combination of RCRA and TSCA waste (ie TCLP and PCB waste
from drums and soil/debris), 6,739 gallons of RCRA liquid (from water
which accumulated on stockpile pads and from drums).
- All waste was transported for off-site hazardous waste disposal.
