The drive train on a tanker carrying 10,000 gallons of Jet A
exploded and punctured the shell releasing 8,000 gallons of fuel
on a perimeter road at an International Airport. The site was
located in a restricted area in direct line with aircraft approach
Fuel was released on asphalt pavement and migrated overland
and 1-mile downstream into airport drainage ditches, tunnels, and
a creek. The airport authority required that a remedial approach
with minimal access and visual disturbances to approaching
aircraft be implemented.
Approximately 6,500 gallons of fuel were recovered from a one mile
section of stream utilizing skimmers, vacuum trucks, wash
down pumps, and a polypropylene rope mop.
An estimated 1,000 gallons of fuel saturated 600 cubic yards of
soils at the release point. 350 cubic yards of soils were
excavated from the bottom of the drainage ditch and placed on a
one foot deep biobed. Soils were cultivated with a disc/harrow.
The remaining 250 cubic yards of soil were treated in the bank
(insitu) employing three (3) horizontal aeration manifolds powered
by a regenerative blower. Ten (10) gallons of HC-2000 (diluted
with 16 volumes of water) were applied on a weekly basis to the
bank and bed bioremediation systems. A sprinkler system was
installed to maintain moisture levels at both locations.
Total petroleum hydrocarbon (TPH) concentrations were reduced
below 200 mg/kg in 16 weeks (99% reduction). Total
heterotrophic plate counts were elevated from 6,000,000 to over
Remtech trained airport personal to maintain the bioremediation
systems and reduce project costs. Remediating soils onsite with
HC-2000 minimized the number of site access and resident time
that met airport authority security and aircraft safety requirements.
