Fast Naphthalene Bioremediation Using Petrox

South Carolina Industrial Site

Petrox microbes were injected in a petroleum ground water plume to remove contamination at an industrial site.  With one application, the petroleum constituents were below detection limits in under six months.

Petrox is a blend of  Pseudomonas sp. formulated to degrade a wide range of petroleum hydrocarbons including BTEX and naphthalene contaminants.  The application of Petrox at the case study site overcame some of the recalcitrance of xylenes and naphthalene that can result in slow remediation.
