Contamination affects both soils and water at sites where, or close to where, industrial activities such as mineral processing, heavy manufacturing and fertiliser and pesticide use occur.
Australia has many potential contaminated sites. These include former factories and tanneries, fuel dumps and chemical stores, service stations, munitions plants, farm livestock dips, timber treatment plants, oil and chemical refineries, landfills and the sediments of rivers, where waste has in the past been piped for disposal.
Contamination has a wide variety of forms, but is usually:
• Inorganic, such as heavy metals
• Organic, such as PAHs, TPH and BTEX
• Radionuclides, such as uranium
The presence of contaminated land does not immediately mean that there is a risk to humans. For a contaminant to be a risk to humans, it must first be bioavailable. This means that it must be able to be taken up by humans through drinking water, inhaling dust, dermally (through the skin) or by ingesting plant and animal matter.
The concept of risk assessment depends upon scientifically assessing the extent of bioavailability of various toxic substances in soil or groundwater, and based on the risk identified, the development of a remediation plan which minimises this risk.

Hunter Tech Services Pty Ltd (HTS) aim to ensure that the minimum amount of waste is sent offsite to specialised Waste Management Facilities, whilst maximising the amount of material that can be reused or recycled on-site. The reuse and recycling of material is achieved through on site screening, separation and treatment methods. Wherever possible, HTS will offer innovative alternative solutions to traditional Total Waste Management to save you money and time.
When a contaminated site requires civil works to be installed, above ground structures to be demolished or landscaping works to be conducted as part of the total remedial strategy HTS has the expertise to successfully manage these works. We provide an integrated environmental service that ensures we take responsibility for the success of your remedial works.
