(OTCBB: SSWM) of Delaware, announced it has been invited to present its timely technical success at the ENTECH West '03 Conference to be held at the Long Beach Convention Center Oct, 28 through 30, 2003.

Bruce Beattie, president of SSWM stated, "Today, both regulatory agencies and the regulated community are very concerned with the breakthrough of tertiary butyl alcohol (TBA) in groundwater treatment using conventional activated carbon filtration systems. TBA is the breakdown "daughter" product formed when treating groundwater impacted from release of gasoline containing the clean-fuel oxygenate additive Methyl-tertiary-butyl ether (MTBE). SSWM has successfully developed and is deploying U.S. Patent Pending microbial based technology treatment solutions to meet regulatory agency mandated treated water discharge limits. SSWM presentation at ENTECH West '03 will bring wider knowledge and acceptance of our cost-effective technology breakthrough solutions to potential new clients."
