Using excess soil from the Forrestfield-Airport Link project as fill for the Kenwick site is safe and represents a sustainable approach to managing a valuable natural resource.
All work undertaken on the Forrestfield-Airport Link project is conducted in accordance with the project’s Environmental Management Plans, which involves oversight from a variety of stakeholders including the Department of Water and Environmental Regulation, and an independent environmental auditor accredited under the Western Australian Contaminated Sites Auditor Scheme.
While fill from the Forrestfield-Airport Link project has been tested for PFAS, and very low levels have been found in some samples, the highest readings measured in the project’s fill are lower than the human health and ecological guideline values for indirect exposure given in the PFAS National Environmental Management Plan.
PFAS are ubiquitous and can be found at low levels in soils, surface water and groundwater in most urban areas in WA and nationally. The PFAS levels identified in the fill are not considered to pose a health risk to neighbouring properties. This includes consideration of dust exposure for construction workers, as well as for residents and businesses adjacent to the project site.
