Description:
In 1998, Green Mountain Laboratories, Inc. (GML) and the USEPA agreed to carry out a Superfund Innovative Technology Evaluation (SITE) project to evaluate the effectiveness of GML's Bioremediation Process for the treatment of PCB contaminated soils at the Beede Waste Oil/Cash Energy Superfund site, Plaistow, NH. Treatment involved inoculation/augmenting of the contaminated soils with bulk microbial inoculum and nutrients, and subsequent aerobic degradation. The bulk inoculum was produced on-site by the developer using oatmeal as the substrate, shredded pine needles that provided certain co-metabolite compounds, nutrients and a proprietary consortium of microorganisms.
The results of the technology evaluation are based on data collected from the treatability study conducted in the third quarter of 1998 and are the subject of this report. Results indicate no removal/degradation of the PCBs. At the end of this field treatability study, GML concluded that it may have inadvertently made some fundamental errors in the production and application of the inoculum. Subsequently, GML was given another opportunity to demonstrate its technology's capability in degrading PCBs in the Beede site soil, but at a smaller laboratory scale. In September 2000, GML, carried out a limited number of bench-scale tests to reestablish the viability of its process. At the conclusion of the bench-scale tests, GML conceded that, at best the tests were inconclusive and at worst had failed.
