A database of known PFAS associations with industries, processes and products to evaluate potential PFAS within supply chains and the likelihood of legacy environmental releases at subject sites and nearby facilities. 

We have refined a multi-stage desktop protocol that combines the likelihood of a historic PFAS release with potential receptor impacts. The protocol is risk-based and customisable and can be used to identify and rank reputational risks and financial liabilities.  

We are skilled at leveraging targeted and non-targeted analytical methods and advanced sampling techniques, including passive samplers and lysimeters, to gather the necessary information to build a complete picture of PFAS impacts. 

Volatilisation of short-chain and neutral PFAS, such as fluorotelomer alcohols, is proving to be a major PFAS transport pathway that is rapidly gaining regulatory attention. Our team brings expert knowledge and extensive experience of assessing and mitigating the PFAS vapour risks associated with landfills, residential and workplace vapour intrusion, and occupational exposure.  

PFAS testing programs generate large quantities of data, making robust data interpretation challenging and time consuming. We are using machine learning to simplify this process, yielding new insights into the challenges that PFAS present, and the potential solutions.

WSP has focused on the advancement of several PFAS treatment technologies with specific focus on destructive solutions to end PFAS cycling through the environment, lower costs and reduce liabilities. These include:

• Electro-oxidation

• Super critical water oxidation: We partnered with a supercritical water oxidation (SCWO) technology provider to verify and validate the onsite destruction and mineralisation of PFAS remediation wastes, such as spent PFAS-laden ion exchange resin or GAC. 

• Plasma: Low-temperature plasma destruction of PFAS in high-concentration solutions. PFAS rise to the surface of the reactor vessels, assisted by argon gas diffusers, and are fully destroyed in a matter of hours. 

We are exploring the potential of nature-based solutions to remediate PFAS-contaminated sites, to address contexts where traditional methods are impractical, and provide co-benefits to people and nature.

Our team designed, operated and maintained some of the first PFAS treatment systems, and we have been developing and demonstrating separation, stabilisation and destruction technologies since 2015, including: 

• WSP treatability study labs

• WSP treatment trailers

• Full scale treatment systems

From small to large flows, from in-situ to ex-situ, from conventional to innovative technologies, we provide experience-based, scientifically advanced, economically efficient solutions tailored to each site. 

WSP's risk assessors conduct multi-pathway PFAS risk assessments, specialise in dietary exposure evaluations, and routinely develop toxicology reviews and assessments.

WSP has developed a tool to assess the impact of climate change on PFAS contaminated sites for potential remedial options or treatment technologies already in operation. The tool helps with responsible and cost-effective decision-making, strategic planning, and risk management at the site and/or portfolio level. Climate change impacts specifically addressed by the tool include:

• Temperature

• Snow cover

• Precipitation / storm events

• Change in permafrost

• Flora shift

• Fauna shift

• High winds

• Erosion

• Drought

• Wildfires

• Sea level rise / Artic Sea level change
