How does TRS mitigate the downward migration of DNAPLs?
The net effect of our ERH remediation systems is the movement of contaminants, vapors, steam, water and air moving into the system – not away from it. This is due in part to steam/vapor buoyancy, applied subsurface vacuum, and net groundwater extraction. This net effect has been observed consistently on our projects. Contaminant migration outside of the remediation area has never been observed at our sites. There are additional engineering design features that we provide including thermal barriers below and outside the focused treatment region that will intercept any contaminant in the unlikely event migration occurs.
