Executive Summary
Core Consultants Pty Ltd (Core) carried out an acid sulfate soil (ASS) investigation for a proposed residential
development with a single level basement carpark at 47 Witta Circle Noosa Heads.
The results from this investigation indicate that the fill materials across the site have a low likelihood of
containing existing, actual or potential acidity. However, based on the testing carried out to date soils with
actionable levels of potential acidity appear to be limited to the natural soils below 2 m. The calculated liming
rate required for full neutralisation of this potential acidity in the natural material is 31 kg CaCO3/m³
Based on the results of the investigation and the proposed earthwork, the risk of impact to the surrounding
environment is considered low to moderate. Provided that the management measures outlined in Section 7.0
of this report are adhered to and an ASS MP is prepared for the project and implemented, the environmental
risk will be reduced further.
