Project aim

To provide a brownfield site suitable for redevelopment from a contaminated land perspective. 

What we did

Works included:

• Detailed site history review (SHR) prior to demolition to identify potentially contaminating activities (PCAs) and associated contaminants of potential concern (CoPC)
• Conceptual site model and assessment of source-pathway-receptor linkages
• Sampling plan for intrusive investigations, implemented by demolition stage as access became available
• Soil investigations to assess suitability of the site for ongoing ‘mixed use’ (as per the zoning)
• UPSS decommissioning by removal
• Classification and offsite disposal of contaminated soils
• Identification of any ongoing management and/or remediation works (where relevant); and
• Reporting. 

Outcomes

The intention is that the assessment and remediation works will provide the Department of Health confidence that the risks posed by any potential, or identified, contamination to human health and/or the environment from the site during proposed ongoing ‘hospital services’ use (i.e. no rezoning) are low and acceptable.

The Detailed Site Investigation (DSI) report will be a key input to future development on the site. The DSI report will be used by Launceston City Council as part of future development applications for the site to demonstrate that the site is suitable for the proposed use and excavation under the Potentially Contaminated Land Code of the Tasmanian Planning Scheme.
