Geology and Ground Conditions of the PEIR assesses the effects on land and groundwater quality, land instability and mineral resources as a result of the Project. The assessment includes an evaluation of ground conditions and the nature of any contamination present. Part of the assessment includes a review of existing ground investigation data pertaining to the Project site from which a generic quantitative risk assessment has been carried out in accordance with current guidance and best practice. Chemical analytical data have been compared to published assessment criteria and exceedances identified.
The study area includes the Project site and an additional buffer of up to 500 metres. This is considered to be sufficient to enable the identification of off-site potential sources of contaminants of concern, other factors which may have influenced site conditions and/or sensitive off-site receptors that require consideration.
Baseline information on geology, hydrogeology and ground conditions was collected through a detailed desk review of existing studies and datasets.
A site walkover was also undertaken to validate the information collected from the desk review and to identify any existing sources of potential contamination.
The Project site is underlain by superficial deposits including Alluvium, Head and River Terrace Deposits...

A number of previous investigations have been undertaken on the Project site, the review of which has focused on the areas of the site proposed for redevelopment. Elevated levels of contaminants were detected in soil, leachate and groundwater samples taken from various locations, together with elevated levels of ground gas.
A site walkover was undertaken in 20XX in order to ground truth information from the desk study and to identify potentially contaminating land uses.
The desk study and site walkover information was used to identify potentially contaminating land uses. This information was combined together to identify Potential Areas of Concern.
The approach includes ground investigations, together with implementation of a remediation strategy where necessary. The Code of Construction Practice will include measures to prevent and control spillage of oil, chemicals and other potentially harmful liquids, in addition to measures to protect groundwater during construction.
The assessment has considered potential impacts on the underlying aquifers, surface watercourses, human health (construction workers and future site users) and mineral resources. No significant effects have been identified.
Given the measures in place, the Project is not anticipated to contribute to any significant cumulative effects.
