BioGenesis was contracted by Brookhaven National Laboratories in October of 1995 to participate in the joint U.S. EPA/Army Corps of Engineers Dredged Material Decontamination Program. The Firm was awarded this contract after a formal competition with 26 other vendors to propose a method for cleaning 500,000 to 1,300,000 cubic yards of sediment per year for the New York and New Jersey estuaries.
The result of this initial contract was a series of Bench test performed by BioGenesis at its facilities in Oak Creek, WI. These tests were performed on
contaminated sediment dredged from some of the worst areas in the estuary that had been deemed "Areas of Concern." The contaminants targeted for cleanup included Dioxins/Furans (18,000 ppt), PCBs (2,320 ppb), PAHs (19,502 ppm), and Metals (852 ppm.)
After passing through the BioGenesis™ Sediment Washing Process removal percentages on average exceeded 94%. This included 99.4% for Dioxin and Furan, 95.3% for PCBs, 84.7% for PAHs, and 93.3% for Metals. These tests helped to prove conclusively the effectiveness of the BioGenesis™ Washing Technology as applied to an incredibly complex and difficult sediment matrix.
Based on the exceptional results of the bench tests, BioGenesis was again contracted by Brookhaven National Laboratories in July of 1997 to perform a 1,000 cubic yard pilot during the third quarter of 1998. This has subsequently been increased to 15,000 cubic yards. Permiting and mobilization are ongoing for this project. During the course of the project production scale equipment will be built for the full-scale facility that is expected to be operational some time during the 1st or 2nd quarter of 1999.
