Cleanup Objectives: Contain an unlined landfill containing nearly 38,000 cubic yards of soil contaminated by waste such as pesticides and asbestos debris

Greener Remediation Strategy:

Employed BMPs for controlling stormwater runoff and sediment erosion during construction of a landfill cover

• Installed a woven geotextile silt fence downgradient of construction to filter sediment from surface runoff
• Added a “super-silt fence” (woven geotextile with chain-link fence backing) on steep grades surrounding the landfill
• Constructed berms and surface channels to divert stormwater to sediment ponds
• Emplaced erosion control blankets to stabilize slopes and channels until vegetation was established
• Hydroseeded the landfill cover with native seed to foster rapid plant growth

Results:

• Effectively captured sediment at super-silt fence despite heavy rain of Hurricane Floyd
• Avoided damage of infrastructure used in site redevelopment
• Reestablished 100% vegetative cover within one year

Property End Use: Redevelopment for office and light industrial space
