Diesel Bioremediation of Pond Sediment and Stormwater  

OFF-ROAD DIESEL POND SPILL PROBLEM

A developer’s 8,000 gallon temporary fuel storage tank was sabotaged during construction of a10-acre site and an estimated 4,000 gallons of off-road diesel fuel were released to an erosion control pond.  Remtech was engaged to remediate the problem.

OFF-ROAD DIESEL DETENTION POND BIOREMEDIATION SOLUTION

Two filtration dams were installed downgradient from the pond in the receiving stream.  A river boom was placed immediately in front of the pond outfall structure.

Stormsewers were flushed with water to move product to the detention pond.  Remtech mobilized its all-terrain vacuum tankers and recovered an estimated 3,500 gallons of fuel from the pond.    

90-tons of fuel saturated sediment near the pond’s effluent structure were excavated and transported to a soil recycling facility.

OFF-ROAD DIESEL DETENTION POND BIOREMEDIATION COST/BENEFITS

Approval was received from an EPA Region IV Onscene Coordinator to treat an estimated 500,000 gallons of stormwater diesel contact water and 500 tons of remaining sediment insitu with Remtech’s HC-2000 native bioremediation accelerator to break down residual petroleum hydrocarbons and remove sheens from the pond.  No confirmation sampling was required due to regulatory confidence in the degradation efficacy of HC-2000.  This saved the client thousands of dollars compared to removal of remaining stormwater and sediment.
