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.

You might prefer this method of remediation compared to a permanent system since it is less intrusive and typically less expensive.

You might be trying to size a permanent system at your site and you want to test vacuum, vapor flow, and extraction rates.

LP Environmental has performed hundreds of high vacuum extraction events.

  • 2 hour events
