Fast creosote bioremediation was recently demonstrated by a user of a custom blend of CL Solutions organisms. The environmental consulting firm applied the microbes to finely shredded wood that had been saturated with creosote. The initial testing results after bioaugmentation showed a reduction of the creosote concentration by 57% in just 7 days. The concentration measured as total recoverable hydrocarbons decreased from 3,453 mg/kg to 1,497 mg/kg.
CL Solutions provides a special consortium of microbes for oil-contaminated water treatment. Under various conditions, the oil removal rate was as much as 1,300 mg/L/day. In some situations the remediation goal is simply to remove the visible sheen or separate-phase oil. With aeration, CL Solutions microbes were able to remove the visible oil layer and reduce the TPH concentration from 29% to less than 1% in 30 days at a waste oil lagoon.

Benzo(a)pyrene is a difficult remediation challenge. It is resistant to biological and chemical destruction and extraction from soil. CL Solutions Custom Blend microbes, however, have successfully remediated benzo(a)pyrene and other PAHs in soil during ex situ land farming treatment. By placing the contaminated material in windrows, controlling the temperature and moisture, the addition of Custom Blend microbes has reduced the benzo(a)pyrene concentration by as much as 330 ug/kg/day.
The same approach works on high as well as low concentrations. At a site in Oregon, the benzo(a)pyrene concentration was reduced from 140 ug/Kg to below detection limits in 7 days. At a site in Ohio, the benzo(a)pyrene concentration was reduced from 28,000 ug/kg to 3.8 ug/Kg in 60 days. At both sites, Custom Blend microbes effectively treated the full suite of PAHs along with the benzo(a)pyrene.
