Advantages & Scope of application

ET-DSP™ is eaqually effective in both the VADOSE & SATURATED ZONES

• Wide range of organic contaminants: chlorinated solvents, hydrocarbons, BTEX, PAH, creosote...
  
  
• Ideally suited to extreme conditions
       Source of contamination: L&DNAPL
       Vadose and saturated zones
       All types of lithology: clay, sand, silt, peat...
       Creation of secondary porosity in impermeable lithology (clay)
       Heterogeneous lithology: interbedded layers – lenses
       Deep contamination (>20m)
  
  
• More than 95% of contaminant mass reduction (VOC)
  
  
• Rapid Treatment: 6 to 8 months duration
  
  
• Safety Performance: zero recorded accidents
