Diesel fuel spill under railyard tracks

Site description and location - Railyard in Fort Wayne.

A diesel fuel spill located under the railroad tracks in a busy railyard. The scope of the project was to treat the contaminated soil and the groundwater located under the tracks without disrupting the train traffic. Because of the busy train and road traffic digging up and treating the diesel fuel spill was not a treatment option.

Recommended Treatment Method (in-situ) : The area contained mostly gravel and hard soil surface along with some grassy patches.
To treat the area we developed a matrix that contained 10 injection points. Each of the sites had vertical holes drilled and PVC pipes were put into the hole. The 10 injection points allowed allowed us to use pressure injection and gravity feeds to add microbes to the area.

The Oppenheimer Formula III was introduced into these sites in a slurry form. The slurry was made by mixing the formula with the BioCatalyst, no other products were used.
The weather conditions during treatments were mostly raining with temperatures consistently in the mid 50's. After treatment the injection points were cutoff at ground level. This allowed us to monitor the groundwater as well as allow us to re-treat potential hot spots if they arose.



The diesel spill along the traintracks and the gravel areas next to the tracks were treat successfully without any disruption to the freight trains.

Actual Time Frame – 60 days.

These case studies are only intended to represent a cross section of sites where our family of Oppenheimer products have been used. It is to demonstrate the diverse range of contaminants that can be successfully and effectively bioremediated by our products and applications.
