Sub-Surface Waste Management of Delaware, Inc. (SSWM) announced Thursday that it has received authorization from the PROFEPA, the environmental policy enforcement regulatory agency of Mexico’s Secretary of 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, said,“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 $1.4 million and with little, if any, downtime in production,”
Using both in-situ and ex-situ technology, SSWM was able to convert toxics into carbon dioxide and water. Beattie described the project as a “watershed project for PROFEPA,” as it was the first project to use both in-situ and ex-situ technology in the same site.
