REMEDIATION OF FORMER MANUFACTURING SITE
With historical industrial uses including whitegoods manufacturing and metal foundry operations, the 2.5 ha former whitegoods manufacturing site was subject to impacts including chlorinated solvents and had been notified to the NSW EPA under Section 60 of the Contaminated Land Management Act 1997.
EI’s work included data gap closure investigations, active remediation & validation of impacted soil and groundwater, vapour intrusion modelling, natural attenuation assessment and development of Stage-specific EMPs for commercial, residential and recreational open space redevelopment.
The natural attenuation assessment is currently ongoing, and the existing groundwater monitoring dataset appears to support the feasibility of Monitored Natural Attenuation as an appropriate remediation strategy for low-level, residual groundwater concentrations.
VALUE ADDED / BENEFICIAL OUTCOMES FOR CLIENT:
Assisted in making the site suitable for the intended land uses, with Site Auditor sign-off and Council approval, which enabled project stages to be constructed sequentially with minimal delay. Also maintained communication with NSW EPA in compliance with regulatory requirements.
