QDS is a very professional company to work with. They remediated a difficult site with great skill to a high standard, on time and on budget and I would not hesitate to use them again or recommend to others.

  • Bioremediaton
  • Stabilisation / solidification
  • Soil processing and materials management
  • Thermal desorption
  • Asbestos in soils
  • Chemical oxidation
  • Excavation and disposal
  • Japanese Knotweed
  • Phytoremediation
  • Spill response

In-situ

  • Air sparge
  • vacuum extraction
  • Dual phase vacuum extraction (multiphase recovery)
  • Chemical oxidation (multiple methods)
  • Free phase recovery (LNAPL &  DNAPL)
  • Flow path management
  • Groundwater re circulation
  • Pump and treat
  • Plume delineation and management
  • Thermal (steam stripping)
  • Thermal (conductive heating)
  • Aerobic bioremediation
  • Anaerobic bioremediation (Enhanced Reductive Dechlorination)
  • In-situ chemical reduction
  • Monitored Natural Attenuation
  • Surfactant flushing
  • In-situ stabilisation
  • Cut-off walls and permeable reactive barriers

Water treatment

  • Automated pumping systems with telemetry
  • Silt / solids separation
  • Activated carbon filtration
  • Precipitation / coagulation / flocculation
  • pH amendment
  • Dosing systems
  • Ion exchange
  • Air stripping
  • Methane stripping
  • Ammonia treatment
