Example Abstract
U Creosote Superfund Site, Operable Unit 2
Site Name and Operable Unit:
Live Oak, Florida
Location:
U.S. Environmental Protection Agency Region IV
Regulatory Oversight:
Florida Department of Environmental Regulation
U.S. Army Corps of Engineers, Jacksonville District
Contractor Oversight:
Cleanup, Inc., Cleantown, FL
Remedial Action Contractor:
Sludge and soil contaminated with lumber treatment chemicals (including
Waste Source:
creosote and small amounts of pentachlorophenol)
Polycylic aromatic hydrocarbons (PAHs) designated as total carcinogenic
indicator chemicals (TCIC), including benzo(a)anthracene, benzo(a)pyrene,
benzo(b)fluoranthene, chrysene, dibenzo(a,h)anthracene, indeno(1,2,3-
c,d)pyrene
Pentachlorophenol (PCP)
Land Treatment:
Technology:
♦ Contaminated soil with TCIC contractions <5,000 mg/kg was excavated
and placed in 4- to 12-inch-thick lifts and inoculated with PAH-degrading
microorganisms.
♦ Composite samples were collected from subplots each quarter, until TCIC
concentrations were detected at less than 100 mg/kg.
♦ Upon confirmation that cleanup goals had been met, the site was backfilled
with clean soil and revegetated.
♦ Groundwater at the site is to be monitored for five years.
Full-Scale
Cleanup Type:
Land treatment designed to reduce TCIC concentrations to 100 mg/kg within
Purpose/Significance
two years of initial placement and inoculation.
of Application:
8,100 cubic yards of contaminated soil were land treated
Type/Quantity of
Media Treated:
Land treatment: 1/19/97 to 7/24/98
Period of Operation:
Groundwater monitoring: Ongoing
Soils >100 mg/kg, but <5,000 mg/kg TCICs to be land treated to 100 mg/kg.
Regulatory Requirements/
Remediation objectives to be met within two years or progress shown toward
Cleanup Goals:
meeting objectives. If this could not be shown, alternative measures would be
considered.
Five years of groundwater monitoring to be implemented upon completion of
construction.
Sampling conducted in June 1998 indicated that TCIC concentrations were
Results:
<100 mg/kg, ranging from 23 to 92 mg/kg in the eight subplots.
Cleanup goals were attained within 18 months of land treatment startup.
