NORWOOD, MA — (MARKET WIRE) — 05/11/2005 — Global BioSciences Inc. (“GBI”), today announced rapid, cost-effective remediation of methyl tertiary butyl ether (MTBE) from soil and groundwater in multiple sites using its proprietary Butane Biostimulation Technologies (Butane Biosparging , Butane Bioventing, collectively “BBT”).

We are very pleased by these results,” said Felix Perriello, GBI President and inventor of BBT. “Not only did BBT remediate MTBE, it also remediated other site-specific pollutants and did so rapidly. Most remediation processes take years, using either harsh or expensive treatments, genetically altered organisms or soil excavation. Few effectively treat both contaminated soil and groundwater. Our results were obtained in 15 months or less, with none of those undesirable characteristics. Speed can be especially critical when water supplies are involved or threatened.”

MTBE reduction data:

Site #1: 36,000 to 3000 µg/L in 15 months, despite a new leak discovered
at 6 months.

Site #2: 544,000 to 14,000 µg/L in just 9 months.

Site #3: 16,000 to 100 µg/L in just 7 months.

Site #4: 206,000 to 4000 µg/L in just 6 months.

Site #5: 31,000 to 200 µg/L in just 4 months.

“MTBE pollution understandably concerns environmental and health officials,” said Paul Abrams, M.D., J.D., GBI Executive Chairman. “GBI’s patented technology remediates MTBE, as well as other pollutants, providing a solution for this problem for governments, local water companies and private companies. Applying BBT widely could dramatically minimize this health hazard.”

Among the potential applications for BBT remediation: closed military bases for return to recreational, residential or industrial use; gasoline stations; refineries. Gasoline stations might be outfitted with BBT preventatively to remediate any problem when a leak begins before contaminants reach the water table.
