Contaminated Drilling Muds & Fluids
Drilling mud commonly contains bentonite, additives (barite, chalk or hematite), thickeners, deflocculates and other chemical contaminants. WestRex utilises a range of technologies to treat these contaminants and then recover the treated liquid and solid materials for processing and beneficial re-use.
PFAS Liquids & Sludges
Per- and Poly-fluoroalkyl substances (PFAS) are hazardous and extremely mobile contaminants that persist in the environment and are generally associated with historic fire-fighting activities involving the use of Aqueous Film Forming Foam (AFFF).
WestRex is fully licensed to receive, store and consolidate PFAS liquids and sludges at our Jackson facility. PFAS liquid acceptance is subject to review of NATA-accredited laboratory testing reports and approval by our on-site chemist.
Sewage & Septic
WestRex provides a beneficial reuse program for sewage, septic and organic liquid wastes, via our on-site composting activities. Organic liquids include kitchen grease trap waste and other biodegradable liquids suitable for composting. The compost produced is tested for compliance and quality, before being utilised in broad-acre applications and other suitable uses.
Contaminated Soils
WestRex provides contaminated soil treatment and disposal services at our Jackson facility, particularly for soils with contaminant concentrations above landfill acceptance criteria and require prior treatment. Our treatment methods include bioremediation, chemical fixation, chemical oxidation and stabilisation. Soil contaminants we can successfully treat include hydrocarbons, heavy metals, PAH’s, acid sulphates and salts.
Contaminated soil acceptance at our Jackson facility is subject to review of NATA-accredited laboratory testing reports and approval by our on-site chemist.
WestRex can also provide contaminated soil transport and disposal services, through our broad network of industry partner haulage contractors and licensed landfill disposal facilities. We undertake a full review of the analytical data and arrange landfill acceptance letters and/or interstate consignment authorisations. We can also assist with preparing soil disposal permit and waste levy exemption applications and provide guidance on completing waste tracking documentation. Our service includes provision of weighbridge dockets and summary reports to our clients.
