About

Emerge Associates was engaged to undertake a site investigation to provide due diligence advice to support the acquisition of the 4.7 hectare commercial property which was comprised of multiple tenancies. Tenants operating from the site were involved in a range of commercial and light industrial activities which included wash down bays, motor vehicle repairs and an operational service station. The due diligence investigations included soil and groundwater investigations which identified a number of areas of hydrocarbon impacts to groundwater and redundant infrastructure including a number of underground storage tanks (USTs). The impacts which were identified were found to be isolated and did not provide a risk to human health given eh commercial/ industrial land use undertaken within the site.

Following acquisition of the property Emerge Associates was engaged to remove and validate the USTs, remove and validate other redundant infrastructure including two wash down bays, and remove and validated shallow impacted soils. Emerge Associates undertook investigations to identify the nature and extent of acid sulfate soils (ASS) to facilitate the installation of a new gravity sewer to service the development.

The investigations, remediation and validation were able to facilitate a ‘Remediated for restricted use’ classification pursuant to the Contaminated Sites Act 2003, with restrictions limited to those areas where residual hydrocarbon impacts are present, predominantly in groundwater associated with the service station. This classification enabled the redevelopment of the remainder of the site.
