VEG Remediation Technology

Green Remediation

Endpoint owns multiple green and sustainable technologies with a proven track record of treating chemical contamination in various media, including soil, water, and air.  These technologies target comprehensive cleanup of various media for unrestricted reuse, while significantly reducing costs and the carbon footprint of remediation efforts.

Among Endpoint’s green and sustainable technologies is its award-winning Vapor Energy Generator (VEG) Soil Remediation technology, which includes both ex-situ and in-situ applications.  The ex-situ component of the VEG technology utilizes a mobile, fully enclosed soil remediation system capable of thermally treating petroleum hydrocarbons, chlorinated solvents, munitions constituents, pesticides, PCBs, PFCs, and select metals (including arsenic, mercury, zinc) in soils to achieve unrestricted reuse levels (i.e, non-detect or residential cleanup goals).  Use of this technology eliminates the need for offsite landfill disposal of impacted soils, eliminates waste-generator liability, and significantly reduces the carbon footprint of soil remediation.  This highly efficient technology is scalable to any size project, while significantly easing the permitting process through the use of Endpoint’s emission-reducing  filters; and most importantly, significantly reducing the cost of remediation relative to offsite landfill disposal, traditional thermal desorption technologies, and other in-situ and ex-situ remedial alternatives.

A brief brochure of the technology may be accessed at VEG Soil Remediation Technology-2016.

Recognized and award-winning applications of the VEG technology have included its use on multiple US Army Corps of Engineers (USACE) projects, including at USACE Engineer Research and Development Center-Waterways Experiment Station (ERDC-WES) Facility, Vicksburg, MS.  USACE’s recognition of Endpoint’s work on this project may be accessed at: USACE-ERDC Award

The VEG Technology has been successfully applied on pilot and/or full-scale studies for the USACE Omaha District, USACE Alaska District, USACE Louisville District, and with the Air Force Civil Engineer Center (AFCEC) in coordination with Corvias Military Living.  Active and/or upcoming projects in 2016 include both in-situ and ex-situ applications of the VEG Technology for treatment of petroleum hydrocarbons, PCBs, pesticides, and mustard (chemical warfare) agent for the Army National Guard Bureau, USACE Los Angeles and Omaha Districts, the US Navy (NAVFACSW), and the Joint Project Leader for Elimination team at the Aberdeen Proving Grounds (MD).  In addition, Endpoint has recently completed a bench-scale study performed in collaboration with the Colorado School of Mines and CH2MHILL, successfully treating PFCs in soil.  Documentation of this bench-scale study may be accessed at: VEG Bench-Scale- PFCs-Soil.  

At the core of the VEG system is a patented steam generator, which also allows for multiple other ex-situ and in-situ remediation applications including in-situ steam injection for remediation of VOCs and munitions constituents,  enhanced NAPL recovery applications for removing trapped/weathered free product in the subsurface and enhancement of crude oil extraction from oil wells.  Enhanced free product recovery from the water table using the VEG is highly effective in mobilizing and capturing residual/imobile free product otherwise trapped at or beneath the water table, while serving as a more cost- and energy-efficient alternative to electrical resitivity heating and traditional steam injection technologies.  Ex-situ VEG applications to clogged oil pipleines have also proven to be highly effective, resulting in mobilization and recycling of crude oil otherwise clogged in above-ground pipelines and elimination of the need for disposal of clogged pipelines as hazardous waste.  The ex-situ vapor energy generator has also been successfully used for thermal treatment of VOCs from process water and/or groundwater extracted as part of pump-and-treat technology.
