The effectiveness and success of the DPE/MPE technology is well documented in the literature. The EFR® process provides the following additional benefits:

• Cost effective (an average ~$30/equivalent gallon for the removal of liquid, dissolved, and adsorbed phase gasoline and diesel)
  
• The EFR® process is extremely mobile (set up and breakdown is typically 30 minutes)
  
• Onsite personnel can provide real time data and make effective system adjustments quickly and accordingly to maximize system performance. The system performance is monitored continuously by experienced personnel resulting in maximum VOC removal.
  
• The system is nonintrusive and can be connected to as many as eight monitoring/recovery wells
  
• The vacuum equipment is much larger than will normally be installed at a UST site (e.g. the vacuum pumps are rated as high as 100 horsepower, 27 inches mercury vacuum, and 880 CFM "open air" flow)
  
• No expensive or time consuming feasibility studies
  
• "Pay as you go" remediation - no initial capital cost or O&M costs
  
• Can be utilized at any time during the "life cycle" of a site (i.e. emergency response, initial abatement, interim remediation, corrective action, enhancement at fixed system sites)
  
• Enhances aerobic biodegradation
  
• Excellent for source removal - ideal compliment to RBCA
  
• High vacuum enhances groundwater removal rates - can remove water from as deep as 150 feet
  
• Can be utilized to collect pilot test and equipment sizing data for fixed (e.g. SVE, DPE/MPE) systems
  
• Sites have been "cleaned up" after a single EFR® event
  
• Applicable for DNAPL sites
  
• Applicable for karst and/or fractured bedrock aquifer
