TEVET
On-Site Treatment
Thermally Enhanced Vapor Extraction Technology
Is Your Soil Contaminated
with Chlorinated Solvents?
If your soil is contaminated with chlorinated solvents like TCE, PCE and/or other VOC’s, our process, TEVET, has been found highly effective to meet your state required treatment standards.
Want to save 30-50% over traditional
Trans and Disposal methods?
TEVET’s process eliminates the need to transport your soil contaminated with chlorinated solvents off-site. Once the soil is treated, it is able to be reused at your job site.
How does a treat until clean
Guarantee sound?
No two piles are exactly the same. Our treat until clean guarantee means that we will keep treating the pile until the chlorinated solvent level results you require are met, or there is no charge for that pile.
What is TEVET?
Thermally Enhanced Vapor Extraction Technology – TEVET – is an on-site, ex-situ process that provides maximum flexibility for hot spot excavation and treatment of chlorinated solvents – Volatile Organic Compounds (VOC), BTEX, (benzene, toluene, ethylbenzene and xylene), PCE and/or TCE contaminated soil. TEVET treats soil in batches of up to 1000 tons. It takes approximately 2.5 days to build, 6 days to treat, and 2 days to dismantle. TEVET can be scaled to have up to 4 piles of 1000 tons treated at any given time.
The TEVET process provides for direct analysis of the impacted soil. After 6 days of treatment, a sample is taken to a certified lab to verify that the level of chlorinated solvents has met the cleanup criteria contaminant level. The pile will continue to be treated until treatment standards are met. The contaminated air goes into a carbon vessel for scrubbing prior to being released back into the atmosphere – No Part B permits are required.
TEVET is usually more cost-effective for sites with a large lay-down area and difficult and/or multiple hot spot locations requiring excavation equipment to reach them. Through the use of electrical generators and propane tanks in the thermal treatment process, the TEVET process is completely portable and adjustable to site and soil conditions. TEVET is a totally mobile operation and can be set up at any location on a site.
