Contaminated Land and Soil Remediation

In dealing with the impact of site contamination and land remediation, governments, local authorities and organisations are increasingly focusing on sustainable solutions that support human health and the environment. 

In an increasingly urbanised and densified environment, the demand for land is rising. As greenfield sites become scarce, there is a need to rehabilitate existing sites for new uses.


WSP removes and manages all the complexities and liabilities associated with historic contamination, leaving our clients free to focus on the future of their business. We can mitigate the risks posed by contaminated land, protect current assets through monitoring and management, and future-proof to cope with an ever-changing regulatory landscape and climate. 


We have a strong track record across a diverse range of multidisciplinary environmental investigation, management and remediation projects.


Minimising Life Cycle Costs and Increasing Asset Values

By understanding the drivers that matter to shareholders, management teams and regulators, we craft holistic solutions to ensure our clients’ assets are monitored, managed and protected to minimise life cycle costs and maximise higher-end values, while remaining environmentally compliant.


Our engineers, biologists, chemists, geologists, hydrogeologists, toxicologists and hazmat specialists combine their knowledge of ground conditions – with practical and innovative investigation, diagnostic and characterisation techniques – to accurately profile client sites. 


Providing Comprehensive Services

Incorporating the impacts of climate change into our solutions, we are leading the way in sustainable remediation and engineering and have an established track record delivering successful projects of all sizes across a multitude of sites, land uses and industries – chemical, pharmaceutical and biotechnology, roads and rail, oil and gas, mines and quarries, industrial and brownfield sites, commercial developments and residential buildings. Where appropriate we work with our remediation experts who apply advanced tools and technologies to design and implement on-site remediation solutions.
