About the AECOM reports
AECOM Australia Pty Ltd (AECOM) was engaged to provide Transurban with this factual comparison of analytical results for per- and poly-fluoroalkyl substances (PFAS) in groundwater samples, reported as part of the West Gate Tunnel Project, against relevant regulatory screening criteria.
Figure F1 shows the approximate location of the tunnel alignment and subject groundwater sampling locations (Appendix A). All data referenced by AECOM in this report were provided to Transurban by the CPB John Holland Joint Venture, the builder of the West Gate Tunnel Project.
