Crude oil and refinery waste in a pond

Site description and location - Crude oil and refinery waste in Mexico

For years refinery and oil field waste had been dumped into the marsh adjacent to a large residential community. The waste oil had also started seeping into the local groundwater. The area included three large ponds including a bermed area, 3 meters deep, containing a mixture of 60% oil-tar in water. The total area held approximately 3,400 cubic meters (m3) of contaminated soil and oily sludge material.

The soil around the ponds was mixed with the dyke walls to achieve a uniform TPH level of 89,650 PPM. The Oppenheimer Formula I, nutrients, and biocatalyst were mixed together, and with the use of a heavy duty slurry pump, the area was converted into a giant bioreactor. When the TPH of the slurry reached 18,000 PPM, 6,000 cubic meters of soil was excavated and land farmed offsite.



The toxic sludge pond was converted into viable farmland for the village.
Improved air quality
The site was remediated 50% ahead of schedule.
The final TPH level was less than 300 parts per million (ppm)
The project was completed in 180 days (six months) 50% ahead of schedule.

Actual Time Frame – 180 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.
