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. Fuel was released on asphalt pavement and migrated overland into a grass lined stormwater drainage ditch and into Mud Creek.
Approximately 6,500 gallons of fuel were recovered from a 1-mile section of stream utilizing skimmers, vacuum trucks, wash down pumps, and a polypropylene rope mop.
An estimated 1,000 gallons of fuel impregnated 600 cubic yards of soils at the accident site. 350 cubic yards of soils were excavated from the bottom of the drainage ditch and placed on a one foot deep biobed. These 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. An automated sprinkler system was installed to maintain moisture levels at both locations. Remtech trained airport personal to maintain the bioremediation systems.
A sixteen (16) week treatment program is anticipated to reduce total petroleum hydrocarbons (TPH) concentrations to below Georgia Department of Natural Resources regulatory limits. 40 days into the treatment program, total heterotrophic plate counts were elevated from 6,000,000 to over 100,000,000 CFU/gm and up to 85% total petroleum hydrocarbon reductions had been achieved.
