HRL worked on a remediation project for an oil and gas production company in Garfield County, Colorado. Approximately 2,700 cubic yards of drill cuttings are being landfarm bioremediated on a well pad site. The drill cuttings were produced as a result of drilling seven wells on the pad site location. Sawdust and other bulking agents were added to the drill cuttings and landfarmed for 12 months by the oil and gas producer, but were not able to be remediated to below COGCC Table 910-1. The drill cuttings contain Diesel Range Organic hydrocarbons and Poly-Aromatic Hydrocarbons which exceed COGCC Table 910-1 standards.
