SSWM Subsidiary Progresses on $14MM 
Proposal Backlog & ERC Contracts

Specific Contract Terms, Project Logistics 
and Financial Guarantees Put into Place 

CARLSBAD, CA (08/08/06) -- Sub-Surface Waste Management of Delaware, Inc. (OTCBB:SSWM), announced that its Mexico subsidiary company Environmental Tec International, S.A. de C.V. (ETI), continues to negotiate specific contract terms and conditions and project logistics in its previously announced $14 Million in written and submitted proposal backlog of work in Mexico as well as additional contract aspects of the Emergency Response Centers (ERC) project in Veracruz.

Bruce Beattie, CEO of SSWM, stated, "We continue to work on our submitted proposals to negotiate final contract terms and conditions acceptable to the company and its clients for individual projects as well as the Veracruz emergency response centers. Last week for example, the principals of ETI met with officials in the State of Veracruz to address third party financing guarantees for the Deutsche Forfait Bank (http://www.defag.de) emergency response equipment lease commitment which under Mexican law requires a first floor national bank's participation to accept foreign offshore originating funds. Our participation in these meetings was paramount as we are establishing a business model that could be adopted by many other states as they choose to implement emergency centers."

Beattie continued, "ETI staff also worked with representatives from the National Autonomous University of Mexico (UNAM) and resolved contract concerns in principle with the Federal Electricity Commission (C.F.E.) for the generating plant in the south of Mexico, in Merida, Yucatan, at Nachi Cocom. These negotiations will allow the company to mobilize to the site in the near future."

Beattie further elaborated, "At the personal request of the Governor of Puebla, ETI staff reviewed the laboratory sample analysis collected during site visits two weeks ago and crafted our engineering approach and cost to address cleanup at these critical impact release sites. The cost proposal, produced in both English and Spanish, will be presented this week to Puebla officials for approval. We continue to develop, track and negotiate all our project opportunities in Mexico very carefully and will keep our shareholders informed of important developments as they occur as well as specific contract values as they are awarded."
