CARLSBAD, Calif.--(BUSINESS WIRE)--April 21, 2006--Robert Brehm, CEO of U.S. Microbics, Inc. (OTCBB:BUGS), an innovative environmental solutions provider to international political leaders, announced today that it is celebrating the 36th anniversary of Earth Day this week on April 22 by applauding the state governors in Veracruz and Puebla Mexico for adopting pro-active environmental policy that embraces environmental stewardship as a tool for economic development including attracting foreign investment, stimulating the local economy with jobs, and providing clean water, soil and air for their constituents.

Robert Brehm, CEO, stated, "Earth Day was founded as a catalyst for environmental education, action and change which crosses all economic and social sectors, states and countries. We can all effect change on a local level by addressing the positive aspects of pro-active environmental policy such as recently adopted by forward-thinking government leaders in Mexico, using environmental technology and services provided by our cleanup subsidiary, Sub-Surface Waste Management (OTCBB:SSWM). Not only will local residents in Puebla and Veracruz soon enjoy the benefits of cleaner water and soil, they will also have new jobs related to emergency environmental cleanup and response thus stimulating their local economies. With environmentally compliant real estate and new environmental policies that meet World Trade Organization requirements, member nations can further invest capital and resources into economic development centers in Puebla and Veracruz further stimulating their economies and benefiting their people while creating significant political capital for their leaders."

Brehm continued, "I am encouraged by our efforts to effect significant economic benefits from positive environmental change. Our economic environmental model is replicatable in most regions of the world using our innovative cleanup technology and project management services coupled with local labor and resources. While our journey may seem complicated with politics and economics, the benefits for the Earth, regional governments and our shareholders could be enormous as more political leaders use our solutions. Our shareholders should be proud of our efforts as we build a new environmental paradigm for all mankind using our unique technology and services."
