VB591^® water Used for Bioremediation of Oil Spills
Underground Storage Tanks and Groundwater Remediation, MA

In accordance with US EPA regulations, a Massachusetts remediation company commenced work on two wells where gasoline contaminants had polluted the groundwater. The company's use of VB591^® made it possible to successfully remediate the wells contaminated with BTEX (benzene, toluene, ethylbenzene and xylene) and MTBE.

The groundwater was treated in-situ without pump-and-treat, bio-venting or air-sparging technologies. A mixture of VB591^® and water was inoculated into the wells to remediate the contaminated groundwater.

Treatment of the wells resulted in reaching the EPA minimum standards of BTEX and MTBE contaminants in groundwater in less than three months for Well Site 1 and less than four months for Well Site 2.

The following graphs provide a summary of the bioremediation results. All data are shown in micrograms per liter (parts per billion). While MTBE data were not available for Well Site 1, MTBE was reduced from 130 ppb to 1.8 ppb in Well Site 2.
