| Hercules 009 Landfill after S/S treatment
and redevelopment. |
Cement-based solidification/ stabilization (S/S)
treatment facilitated the sustainable redevelopment of Hercules 009
Superfund site, a former landfill, into a useful parking lot at an
automobile dealership. The Hercules 009 Landfill Superfund Site is
located on 16.5 acres (6.7 hectares) near the City of Brunswick, Ga.
Hercules manufactured toxaphene, an agricultural pesticide. Seven
acres (3 ha) at the northern end of the site, known as the 009 landfill,
was used to dispose of production wastewater sludge and other waste.
Waste management practices resulted in contamination of drainage ditch
sediments at the facility as well.
The primary contaminants of concern at the
site were volatile organic compounds (VOCs), including benzene,
trichloroethylene (TCE), toluene, and xylenes; other organics, including
dioxin and pesticides; and metals, including arsenic, chromium,
and lead. The contents of the landfill were treated by S/S while
the material remained in-place or in situ.

S/S treatment technology contributed to “green
remediation” and the sustainable development of this Superfund
site. While protecting human health and the environment by immobilizing
hazardous constituents, the technology also improved the construction
properties of the treated materials, enabling reuse. Over 88,000
cu yd (67,000 m3) of landfill contents were treated in
situ avoiding nearly 5,000 roundtrips by dump truck if a “dig
and haul” remedy were used instead.
