PFAS_Source PFAS_Source2 PFAS_Source3

Per- and Poly Fluoro Alkyl Substances (PFAS) are a group of emerging contaminants which have gained significant media and public attention in recent history due to their widespread use and potential risks to human health and the environment. Predominantly found in Aqueous Film Forming Foams (AFFF) which have seen high intensity use on defence, airport and fire-fighting sites, PFAS are also used extensively in the manufacturing and industrial sectors, and may also be found at landfills and within industrial estates.

These compounds persist for an extended period without degrading, are highly mobile, and bioaccumulate; making them exceptionally difficult to remove from the environment. The PFAS assessment and management guidelines are constantly changing as new data becomes available. Effective treatment and remediation technologies are not yet available in the market, due to the emerging nature of these contaminants and pace of industry response. As such, there are very few industry experts with enough experience to undertake site assessment and management/remediation, and provide strategic advice to assist proponents to successfully navigate this issue on their project.

Western Environmental has been very active in the assessment and management of PFAS over many years, and are considered PFAS subject matter experts. Having worked on several major and high-profile projects where PFAS is the primary contaminant of concern, and being responsible for environmental management of construction projects where PFAS occurs, Western Environmental can offer the following high quality, industry-leading services:

  • Preparation of PFAS specific Sampling, Analysis and Quality Plans, including site-specific sampling methodologies for soil, sediment, water, and biota.
  • Detailed PFAS conceptual site modelling
  • Field data collection and sampling programmes in accordance with industry best practice
  • Analytical laboratory selection, procurement and quality control data assessment
  • Preparation of Detailed Site Investigation Reports
  • Tier 3 Quantitative human and ecological risk assessment
  • PFAS Remedial Action Plans
  • PFAS Construction Environmental Management Plans
  • PFAS Dewatering Management Plans
  • PFAS Spoil Management Plans
  • Cost-Benefit Analysis of PFAS disposal options
  • Compliance monitoring for PFAS during works
  • Post-works PFAS Closure Reporting

In addition to the above, Western Environmental also engages in independent research and development relating to PFAS, and is currently the lead consultant in a national consortium undertaking field scale trials for several proprietary PFAS soil and groundwater treatment technologies.
