Contaminated site remediation is critical to keeping our communities and environment safe and healthy. With over 30 years' experience behind us, and with more than 140 major environmental remediation projects successfully completed, we know some of the most advanced and effective ways to safely deal with contaminants

What we do

You can have confidence in the proper management of the contamination hazards we are removing, as well as project schedule and cost.

We work across the following elements:

  • soil remediation
  • sediment remediation
  • surface water remediation
  • groundwater remediation.


All types of contaminants are within our capability, whether organic, inorganic, physical, explosive or radiological. Depending on the problem, we will work insitu (on-site) or ex-situ (off-site).

We also rely on our significant experience whilst assisting clients through the environmental planning and approval process. Venita's aim is to work with clients and regulators to develop outcome based solutions that are seen as win/win for all parties involved.

In any remediation project there are community stakeholders. We have a community relations team with great experience, much of it gained on Australia's largest and most complex sites.

How we do it

Getting involved as early as possible, our tech team will spend time with you to determine or refine the extent of and quantities associated with the problem to be solved. We will then recommend the right strategy to solve the problem from the many options available, including existing or new methods or our own innovation. You can be confident we will know the most effective solution for your problem and will get the job done safely.

There are four broad approaches we can take:

  • physical - segregation or separation of inorganic or organic contaminants using processes such as screening or enhanced soil washing through SourceZone
  • biological - creating conditions to optimise the action of naturally occurring bacteria to destroy organic contaminants
  • chemical - use agents to either destroy or change the chemical nature of the contaminant (often used for metals)
  • thermal - used to vapourise and either recover or destroy the contaminant (often used for complex organic substances).


To ensure everyone involved in a remediation project can visualise what is happening on-site, we use building information modelling (BIM), a standard design documentation and control approach used in the construction industry. We create a '6D' model of the project and site, where on top of the usual three dimensions we add in time (how long the job will take), cost (of all elements of the project) and asset life. For example, we add in all utilities that might be running through a site such as live electricity or water pipes, and map all the hazards such as soil contamination hot spots. Through the use of 6D modelling we can 'view the job before we do the job'.

Managing risk for clients and the community

Remediation comes with risks for our clients so it is important that they can trust us as partners to safely manage those risks on their behalf.

It is essential to protect our communities and the environment throughout the remediation process. Our team carefully manages odours, dust and noise and other health and safety risks to our people and the community. When odorous and volatile compounds are involved, we often contain a site by enclosing it in a building with an emission control system.

Frequent site monitoring ensures we measure air and water quality, odours, and vibrations. By doing this within the site, we identify potential problems before they go beyond the site boundary and become an issue.
