SSWM Mexico Subsidiary Proposal Backlog Surpasses $14 Million

Government Officials Reviewing Proposals Prior to Contract Approval

Sub-Surface Waste Management of Delaware, Inc. (OTC BB: SSWM), announced that its Mexico subsidiary company Environmental Tec International, S.A. de C.V. (ETI), has over $14 Million USD in written and submitted proposals awaiting contract approvals through ETI teaming arrangement with the Zaragoza Graduate School of Studies of the National Autonomous University of Mexico (UNAM). The proposal backlog is in addition to the existing $1.5MM of current work in progress in Mexico.

Bruce Beattie, CEO of SSWM stated, "Since the first of this year ETI and its professional staff working with Dr. Ricardo Lorden and UNAM have been invited by state government officials to review site data and participate on project site walks for seven (7) substantial clean-up projects each with follow on expanded scope of work potentials to assess known releases of toxics that exceed regulatory standards and require accurate assessment to characterize the extent of contamination prior to submitting a work plan for site remediation."

Beattie concluded, "State government officials are showing increased confidence in the ETI/UNAM teaming arrangement as they continue to request proposals for pressing environmental problems including emergency response solutions. As we process these requests, perform the site walks, analyze the data and submit the proposals, we expect contract approvals to be forthcoming in the near future but we can't predict exact times due to changing environmental priorities, state budget considerations and project logistics. However the increased proposal request rate suggests substantial future work is available for the ETI/UNAM team."
