GHD has been leading the response to PFAS (Per-and Polyfluoroalky Substances) as an emerging contaminant for over 10 years. Often found in many industrial processes and legacy firefighting foams, PFAS is widespread and can be difficult to remediate. Leveraging our global footprint to understand and pre-empt the risks, we help impacted industries adapt to mitigate exposure and future liability.
The pathway can be complex. Find out how we can help you every step of the way.
