ERH 100x100   


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


Scope of Application
