Complete Bioremediation of site contaminated with Fraction 2 petroluem hydrocarbons - Environmental - Site Remediation
Delta had been contracted during the 2014 remediation at the well site to apply their bioremediation process to excavated and stockpiled soil contaminated with Fraction 2 petroleum hydrocarbons (F2 PHC). Soil sample results from a 2014 Phase II ESA showed F2 PHC concentrations ranging from 170 mg/kg to 1210 mg/kg, with an average of 586 mg/kg in the four samples from the disposal area. Delta was on the site for around 10 hours using their hopper and amendment sprayer machine to treat the approximately 600 cubic meters of fine–grained contaminated soil. The treated soil was conveyed back into the excavation so the bioremediation process could continue. The client retained Gulo Environmental for sampling of the amended soil piles in May of 2015. Results from the analysis of the samples, taken approximately nine months after the bioremediation process, showed non-detection for F2 PHC, resulting in successful closure of the site.
