| Placement of S/S-treated material at Brunswick
Wood |
The Brunswick Wood Preserving site, a former
wood treating facility in Georgia, is using cement stabilization/solidification
to remediate 84 acres (34 hectares). The facility used creosote, pentachlorophenol
(PCP) with dioxin, and copper/chromium/arsenic (CCA) preservatives
in the manufacturing of railroad ties, telephone poles, and pressure-treated
lumber. Soil and sediment at the facility are contaminated with these
polycyclic aromatic hydrocarbons (PAH), dioxin, and heavy metals.
The multistep remedy started in March 2008. First,
the 11,000 cu yd (8400 m3) of surface soil containing
> 1 ppb of dioxin was excavated. Next, 55,000 cu yd (42,000 m3)
of waste pond sediment and 8,000 cu yd (6,000 m3) of
a CCA pile was unearthed. The final step was the excavation of 600
cu yd (500 m3) of creek sediment.

| S/S Treatment pugmill mixing at Brunswick
Wood |
These materials were staged for treatment and pre-blended
with 10% fly ash. The pre-blended material was processed through
a pugmill where 10% portland cement was added. The S/S-treated material
was then placed and compacted over the former pond areas to form
a very low permeability cap. Slurry walls will
be used to provide additional containment and control groundwater
infiltration at the former pond areas. The treatment and
slurry walls will be completed in the summer 2008. |
