- Biodegradation of 30 Cubic Meters Soil
- 12,100 ppm Diesel
- Levels Reduced to < 10 ppm in 77 Days
Approximately 8,000 gallons of diesel spilled at the Canadian National Railway (CNR) in Spruce Grove, Alberta, Canada, an environmentally sensitive and agriculturally active area.
BioGenesis was contracted by CEDA-Reactor, Ltd. to design and implement a biodegradation procedure to remediate approximately 7,000 ft2 of agricultural farm land, a 4,000 ft2 livestock watering pond, and 5,000 ft2 of trees and brush threatened by the diesel spill.
Canadian regulations required the area to be remediated to less than 100 ppm diesel.

BioGenesis designed and provided technical assistance to CEDA-Reactor to properly, safely, and efficiently remediate the threatened farmland.
On June 24, 1993, under direction from BioGenesis, CEDA skimmed free diesel from the pond and applied 2,100 gallons of 1% solution of BG-850 to the entire area. BG-850 is a BioGenesis developed biodegradation aid specifically formulated for speeding the biodegradation of oils, grease, and other organic chemicals.
On July 8, 1993, under direction from BioGenesis, CEDA tilled the agricultural area, removed dead foliage from trees and brush area and allowed further bioremediation to continue. The area was kept moist.
This process and the BioGenesis chemical formulations reduced the diesel to less than 10 ppm TPH by September 17, 1993. CNR met compliance for this site and no adverse agricultural reactions were reported or observed.
