FORRESTFIELD–AIRPORT
LINK — SOIL CONTAMINATION
633. Hon Dr STEVE THOMAS to the minister representing the
Minister for Transport:
I refer to PFAS-contaminated soil
excavated from the Forrestfield–Airport Link project.
(1) What is the
total volume of soil that is expected to be extracted from the Forrestfield–Airport
Link at the completion of the project?
(2) What is the total volume of PFAS-contaminated soil
that is expected to be extracted from the Forrestfield– Airport
Link at the completion of the project?
(3) How much of this soil is expected to be
temporarily stored at the temporary storage site at 777 Abernethy Road ,
Forrestfield?

I thank the honourable member for
some notice of the question. The following information has been provided by the
Minister for Transport.
(1) The
Forrestfield–Airport Link project will generate approximately one
million cubic metres of spoil from tunnelling works and conventional
excavations.
(2) Low levels of
PFAS have been detected in soil across FAL project excavation locations. The
PFAS levels being encountered by the project are comparable with the low levels
present in soils in most urban areas around the world, including in Australia.
The soil is capable of re-use in accordance with the PFAS national
environmental management plan.
(3) As of the
most recent survey conducted on 17 May 2019, approximately 445 000 cubic metres
of soil originating from construction works
for the FAL project is being temporarily located at 777 Abernethy Road ,
Forrestfield. It is possible that an additional 290 000 cubic metres of soil,
which has yet to be excavated, may require temporary storage.
(4) Perth Airport
has confirmed an interest in utilising excess fill from the FAL project to
facilitate developments consistent with the airport master plan. The project
team continues to work closely with Perth Airport.
