Contamination Remediation

Chemical Warfare Material (CWM) 

Chemical Warfare Materials (CWM) are pollution incidents left either in the wake of a conflict, or the training for a conflict. The relationship between military conflict and the pollution it leaves behind, also known as Toxic Remnants of War (TRW) are complex, potentially damaging to human and environmental health, and can leave a legacy lasting for decades. 

Within Australia, CWM pollution can be found on or near former defence sites and might include old and abandoned WWII chemical weapon stockpiles from Allied troup training exercises; contaminants such as jet fuels, pesticides and heavy metals beneath old training grounds and weapons ranges; and aqueous film forming foams from firefighting training which have seeped into soil and groundwaters. 

OPEC Systems has the capability and specialist training to provide logistical support to any CWM remediation works. Please contact us to explore how we can assist you.  

Hazardous Materials 

OPEC Systems has the capability to undertake complex remediation works, particularly when we engage with specialists from other inhouse teams. These works may include (but are not limited to):  

  • Decommission and removal of above and below ground storage tanks  
  • Sediment and erosion control works 
  • Geophysical surveys  
  • Excavation and offsite disposal  
  • Bioremediation and phytoremediation works  
  • Installation of permeable reactive barriers  
  • Asbestos   

PFAS remediation

OPEC has pioneered technology to remove PFAS contaminants from water. The technology, known as Surface Active Foam Fractionation (SAFF™) is proving itself as the heavy lifter in the PFAS remediation space, with independent test results showing excellent removal rates, particularly for ≥C6 chemistry. Read more here.

SAFF is a simple, replicable and low-cost solution that produces miniscule waste with zero environmental harm. SAFF™ leverages the natural physiochemistry of PFAS molecules to bond to the surface of air bubbles and is an efficient, sustainable and rapid system in comparison to other technologies. 

PFAS chemicals are known as an ‘emerging contaminant’, with health concerns relating to their characteristics of persistence, bio-accumulation and toxicity.  

PFAS is a group of manufactured chemicals used worldwide since the 1950’s to make products that resist heat, stains, oil/grease and water. Over decades, PFAS chemicals work their way through soil to reach the groundwater beneath. 

Within Australia, PFAS contaminants have been identified at hundreds of sites around the country, particularly where fire training has been undertaken. Locations include defence bases, airports and industrial sites.
