Video B.3 (:43)
nated with VOCs (Video B.3). The primary contaminants, trichlor-
ethylene (TCE) and tetrachloro-
ethylene (PCE), originated from an underground process sewer line servicing a metal fabrication facility at M Area.
The soil
and sediments at SRS consist of interbedded sands, silts, and clays, with sands
predominat-
ing. The groundwater table is at a depth of approximately 135 feet.
Solutions
The current
baseline technologies for the remediation of VOC-
contaminated soils and ground- water, primarily variations on pump-and-treat
or excavation, are both inefficient and expensive. Pump-and-treat groundwater
remediation, while proven as an effective method for hydraulic plume control
and for removal of significant contaminant mass (300,000 pounds of VOCs have
