GHD was engaged to provide services associated with the removal
of three abandoned underground fuel tanks at a former service
Station in Wallabadah, NSW. GHD was appointed by the client as the
combined Project Manager/Contract Administrator and Environmental
Consultant for the project. GHD engaged a subcontractor to
establish appropriate safety and environmental controls and
undertake the physical works associated with the removal of the
three tanks and associated infrastructure. Following tank removal
the resulting excavation was validated and impacted soil was
bio-remediated on site to variably allow it to be used to backfill
the excavation or to be disposed offsite to Councils landfill or.
Following remediation the remainder of the site was assessed for
its suitability to continue being utilised for mixed
commercial/industrial and residential use.
The work was assessed, remediated and validated to the
satisfaction of NSW EPA acting on behalf of the NSW Environmental
Trust who funded the project. The site was successfully validated
as suitable to continue operating under a mixed residential and
commercial/industrial land use. The scope of works was also
completed within the timeframe with which Council were required to
utilise the grant provided by Environmental Trust for management
and assessment of site contamination.
