These are different terms for the same type of remediation technology. They rely on vacuum extraction of impacted groundwater, free-product, and vapor phase hydrocarbons from gas/diesel releases as well as other petroleum impacts.

LP Environmental has performed hundreds of high vacuum extraction events.
Our remediation system uses the following equipment:
