SSWM invited for full-scale demonstration of solvents, rocket pollution solution

CARLSBAD, CA, Aug. 20, 2004 (BUSINESS WIRE) -- Sub-Surface Waste Management of Delaware Inc., a subsidiary of U.S. Microbics Inc., recently announced it has successfully completed a full-scale, paid demonstration of its Bio-Raptor^™ treatment system technology for the rapid cleanup of soils impacted with perchlorates at a confidential client's former rocket fuel manufacturing facility.

The company was just informed that it has been asked back to perform a second paid demonstration to treat soils impacted with both perchlorates and volatile and semi-volatile organic compounds (solvents) used as a release agent and process equipment decontamination in the manufacture of rocket fuel and flare charges.

These results will be incorporated into the client's report to the oversight regulatory agency. SSWM has developed a special blend of microbes and nutrients which can rapidly degrade Perchlorates in soils within about a week of initial inoculation.

Cleanup of perchlorates in soil and groundwater present a lucrative market opportunity in western states where Department of Defense contractors manufactured and produced various types of rocket fuels since WWII.

In the United States, ammonium perchlorate is used as an oxidizer in solid rocket propellant, sodium perchlorate is used in slurry explosives and potassium perchlorate is used in road flares and air bag inflators. The U.S. EPA has identified perchlorate users and manufacturers in 44 states and releases in 18 states, estimating that perchlorate affects the drinking water of 15 million people in the United States (see www.epa.gov/safewater/ccl/perchlorate/perchlo.html). Perchlorates have also recently been detected in milk and lettuce in California (see www.ewg.org).
