Contaminated Land

Our environmental teams include specialists like geologists, soil scientists and environmental engineers who undertake assessment of sites for environmental risk related to acid sulfate soils.

We conduct investigations that are compliant with the local regulations including early stage desktop, reviewing known data sources, inspection, and sampling of soils that will be potentially disturbed. Field screening and laboratory testing evaluate the acid producing potential and self-neutralising capacity in some areas of carbonate-rich soils. Management plans include design of treatment areas if required, and work can be supervised and validated to demonstrate compliance.

Our experience of local areas means we can often improve time and cost outcomes by making the best use of natural materials and providing a pragmatic approach towards investigation and management.

Our approach to managing contaminated sites allows us to draw on a multi-disciplinary team of hydrogeologists, environmental scientists, environmental and geotechnical engineers to develop a comprehensive management plan specific to your needs.

Our extensive portfolio includes services like advice about site acquisition and due diligence for environmental site assessments, and groundwater contamination investigation and modelling. We can also monitor and assess the risk of ground gas and provide remediation planning and actions; as well as compliance monitoring and network optimisation.

Human health and ecological risk assessments form an integral part of our approach to environmental site investigations and assist us in developing sound, risk-based solutions for our clients. 

The requirement for risk-based solutions for contaminated sites is becoming more commonplace - and is often a required regulatory approach - and we have significant experience in ensuring our project activities meet regulatory requirements. Our team’s extensive experience covers risk assessment for a number of common situations, such as vapour intrusion which can be associated with petroleum or chlorinated hyrdrocarbons.  

We also have experience in the assessment of risks from emerging contaminants such as perfluorinated compounds, which can be found on a number of facilities including airports and defence bases.

Cardno personnel pride themselves on developing innovative cost-effective remediation technology and working closely with regulatory agencies, local permitting agencies, and the community to ensure that affected sites are remediated and no longer pose a threat or environmental concern to the community.   

We have our own in-house mobile remediation systems and a team with decades of experience in the investigation, design, permitting, procurement, installation, operation and maintenance of a wide variety of remediation technology.
