CARLSBAD, Calif.--(BUSINESS WIRE)--September 18, 2007--U.S. Microbics (OTCBB: BUGS - News), a global environmental enhancement company, announced that the company is increasing its investment position in its environmental cleanup subsidiary, Sub-Surface Waste Management of Delaware, Inc., (OTCBB: SSWM - News). BUGS has previously invested over $6MM into SSWM and is now increasing that investment another $400,000 to help strengthen the SSWM financial statements.

Robert Brehm, CEO of U.S. Microbics, "SSWM has previously identified an environmental transportation company as a potential acquisition and we are in the final due diligence and term sheet negotiation for this company which has historical revenues of $10MM plus per year. Although the acquisition terms are not yet complete, we are preparing for the event by taking steps to strengthen the balance sheet of SSWM by increasing our investment position in the company. We are excited about the future prospects of the target company and the expertise and complementary technology and management we bring to expand its growth."

Brehm continued, "SSWM is going through a metamorphosis from its beginnings as a remediation company to its current emphasis of rebuilding and creating new shareholder value through target acquisitions of environmentally related companies with proven business models. With the SSWM stock price at historically low values and a fast approaching fiscal year end for both companies, adding to our current investment in SSWM seemed prudent for BUGS and also helps SSWM as we prepare for our new business year beginning October 1."
