EMERGENCY SPILL RESPONSE
Carlson responded to a diesel fuel spill that entered an on-site retention pond and a creek near Chicago’s O’Hare Airport. Our Client leases multiple properties adjoining the Airport, from the Chicago Department of Aviation and sublets them to businesses providing airport support functions.
We directed the immediate excavation of impacted sediment and soils and the collection of impacted surface water for off-site remediation and then followed the response action with an extensive Phase II subsurface investigation that revealed the presence of oil-saturated subsurface soils. These impacted soils were then also excavated and disposed off-site. Supplemental investigations included video inspection of sewers and manholes as well as pressure washing these structures to remove potential sources of the residual petroleum.
Carlson personnel also conducted dye tracing studies to evaluate the potential for illicit sewer connections. Because months after the initial spill, a residual oil sheen remains on the surface of the retention pond, a regimen of weekly inspections, product skimming, as well as removal and replacement of absorbent booms continues on an ongoing basis.
