Mexico EPA Agency Approves Cleaned Soil Removal at SSWM Project; Bio-Raptor(TM) and Bugs Successfully Clean up Soils at Manufacturing Company.

CARLSBAD, Calif. -- Sub-Surface Waste Management of Delaware, Inc. (OTCBB:SSWM) announced it has received authorization from PROFEPA, the environmental policy enforcement regulatory agency of Mexico's Secretary of the Environment (SEMARNAT), to begin removal of successfully treated excavated soils that meet regulatory cleanup limits for impacts from hydrocarbon machine oil at this confidential U.S. manufacturing company operation in northern Mexico.

Bruce Beattie, President of SSWM, stated, "This client sought our early involvement to reduce the expense and delays inherent in pursuing conventional cleanup remedies which were estimated to exceed $6MM and take up to 48 months and included shutting down their production facility, an unacceptable alternative for the client. SSWM was called in and we completed a site investigation and engineered a remedial plan using our proprietary microbial blends to bioremediate the constituents of concern inadvertently released. Our cleanup solution took 24 months at a cost to the client of approximately $1.4MM and with little if any downtime in production. We used both in-situ (underground) and ex-situ (Bio-Raptor(TM)) proprietary technology to quickly remediate the soil turning toxics into harmless carbon dioxide and water. New procedures and staff training were also set up to avoid similar spills in the future."

Beattie continued, "This project was a watershed project for PROFEPA since it was the first project to our understanding, under the new environmental laws, that combined ex-situ and in-situ treatment at the same site and fully demonstrated the cost and time savings of our proprietary technology as well as the competency of our engineering staff for solving tough environmental problems with the help and support of government officials with pro-active environmental agendas. We applaud their confidence in our abilities and look forward to many more successful future projects in Mexico."
